GENERAL INFORMATION

GENERAL PRECAUTIONS

Dangerous substances

WARNING: Many liquids and other substances used in motor vehicles are poisonous and should not be consumed
under any circumstances.
As far as possible, try to prevent skin contact with any potentially harmful materials. Substances to be treated with particular caution include (but is not limited to): acid, anti-freeze, asbestos, brake fluid, fuel, windscreen washer additives, lubricants, refrigerant and various adhesives.
Always read the instructions printed on labels or stamped on components carefully. Such instructions should be strictly complied with; they are included to ensure your health and personal safety is not compromised through the incorrect use of the materials to which they relate.
Synthetic rubber
WARNING: Many ’O’ rings, seals, hoses, flexible pipes and other similar items
which appear to be natural rubber, are in fact, made of synthetic materials called Fluoroelastomers. Under normal operating conditions this material is safe and does not present a health hazard. However, if the material is damaged by fire or excessive heating, it can break down and produce highly corrosive Hydrofluoric acid which can cause serious burns on contact with skin.
If skin contact does occur:
Remove any contaminated clothing immediately.
Irrigate effected area of skin with a copious
amount of cold water or limewater for 15 to 60 minutes.
Obtain medical assistance immediately Should any material be in a burnt or over-heated
condition, handle with extreme caution and wear protective clothing (seamless industrial gloves, protective apron etc.). Decontaminate and dispose of gloves immediately after use.

GENERAL PRECAUTIONS AND FITTING INSTRUCTIONS 1

GENERAL INFORMATION

Engine oils

WARNING: Prolonged and repeated contact with mineral oil can result in the removal of natural fats from the skin; this
may cause dryness, irritation and dermatitis.
In particular, used engine oil contains potentially harmful carcinogenic contaminants. Adequate means of skin protection (barrier creams etc.) and washing facilities must be provided.
Avoid excessive skin contact with used engine oils and always adhere to the following health protection recommendations:

Health Protection Precautions

Avoid prolonged and repeated contact with oils, particularly used engine oils.
Wear protective clothing, including impervious gloves where practicable.
Do not put oily rags in pockets.
Avoid contaminating clothes (particularly
underpants) with oil.
Overalls must be cleaned regularly. Discard heavily soiled clothing and oil impregnated footwear.
First aid treatment should be obtained immediately for open cuts and wounds.
Use barrier creams: apply before each work period to help removal of engine oil from the
skin.
Wash with soap and water to ensure all oil is removed (propriety skin cleansers and nail brushes will help).
Use moisturisers after cleaning; preparations containing lanolin help replace the skin’s natural oils which have been removed.
Do not use petrol, kerosene, diesel fuel, gas, oil, thinners or solvents for cleaning skin.
If skin disorders develop, obtain medical advice without delay.
Where practicable, degrease components prior to handling.
Wear eye protection (e.g. goggles or face shield) if there is a risk of eye contamination. Eye wash facilities should be provided in the close vicinity of the work area.

Environmental Protection Precautions

It is illegal to pour used oil on to the ground, down sewers or drains, or into water courses.
Burning of used engine oil in small space heaters or boilers should only be considered for units of approved design and in compliance with the equipment manufacturer’s recommendations. The heating system must meet the regulatory standards of HMIP for small burners of less than 0.4 MW. If in doubt check with the appropriate local authority and/or manufacturer of the approved appliance.
Dispose of used oil and filters through authorised waste disposal contractors and licensed waste disposal sites, or through the waste oil reclamation trade. If in doubt, contact the Local Authority for advice on disposal facilities.

GENERAL INFORMATION
Precautions against damage
CAUTION: Always fit wing and seat covers before commencing work. Avoid spilling brake fluid or battery acid on paintwork;
immediately wash off with water if this occurs.
CAUTION: Disconnect the battery earth lead before starting work, see ELECTRICAL PRECAUTIONS.
CAUTION: Always use the recommended service tool or a satisfactory equivalent where specified.
CAUTION: Protect exposed bearing surfaces, sealing surfaces and screw threads from damage.

SAFETY INSTRUCTIONS

Whenever possible, use a lift or pit when working beneath vehicle, in preference to jacking. Chock wheels as well as applying parking brake.
Jacking
The recommended jacking points are shown in the LIFTING AND TOWING sub-section of the INFORMATION section. Always ensure that any lifting apparatus has sufficient load capacity for the weight to be lifted.
Ensure the vehicle is standing on level ground prior to lifting or jacking.
Apply the handbrake and chock the wheels.
WARNING: Never rely on a jack as the sole means of support when working beneath the vehicle. Use additional safety supports
beneath the vehicle.
Do not leave tools, lifting equipment, spilt oil, etc., around or on the work bench area. Always keep a clean and tidy work area.
Brake shoes and pads
WARNING: Always fit the correct grade and specification of brake linings.
When renewing brake pads and brake shoes always replace as complete axle sets only.
GENERAL PRECAUTIONS AND FITTING INSTRUCTIONS 3
Page 13
GENERAL INFORMATION
Brake hydraulics
WARNING: It is imperative that the correct brake fittings are used and that threads of components are compatible.
Always use two spanners when loosening or tightening brake pipe or hose connections.
Ensure that hoses run in a natural curve and are not kinked or twisted.
Fit brake pipes securely in their retaining clips and ensure that the pipe run cannot contact a potential chafing point.
Containers used for hydraulic fluid must be kept absolutely clean.
Do not store hydraulic fluid in an unsealed container, it will absorb water and in this condition would be dangerous to use due to a lowering of its boiling point.
Do not allow hydraulic fluid to be contaminated with mineral oil, or use a container which has previously contained mineral oil.
Do not re-use fluid from the system.
Always use clean brake fluid or a recommended
alternative to clean hydraulic components.
Fit a blanking cap to an hydraulic union and a plug to its socket after removal to prevent the ingress of dirt.

GENERAL FITTING INSTRUCTIONS

Component removal
Whenever possible, clean components and surrounding area before removal.
Blank off openings exposed by component removal.
Immediately seal fuel, oil or hydraulic lines when apertures are exposed; use plastic caps or plugs to prevent loss of fluid and ingress of dirt.
Close open ends of oilways exposed by component removal with tapered hardwood plugs or conspicuous plastic plugs.
Immediately a component is removed, place it in a suitable container; use a separate container for each component and its associated parts.
Clean bench and provide marking materials, labels, containers and locking wire before dismantling a component.
CAUTION: Absolute cleanliness must be
observed with hydraulic components.
Engine coolant caps and plugs
WARNING: Extreme care is necessary when removing engine coolant caps and
plugs when the engine is hot and especially if it is overheated. To avoid the possibility of scalding allow the engine to cool before attempting coolant cap or plug removal.

GENERAL INFORMATION
Dismantling
Observe scrupulous cleanliness when dismantling components, particularly when brake, fuel or hydraulic system parts are being worked on.
CAUTION: A particle of dirt or a cloth
fragment could cause a serious
malfunction if trapped in these systems.
Blow out all tapped holes, crevices, oilways and
fluid passages with an air line. Ensure that any O-rings used for sealing are correctly replaced or renewed, if disturbed during the process.
Use marking ink to identify mating parts and
ensure correct reassembly. Do not use a centre punch or scriber to mark parts, they could initiate cracks or distortion in marked components.
Wire together mating parts where necessary to
prevent accidental interchange (e.g. roller bearing components).
Wire labels on to all parts which are to be
renewed, and to parts requiring further inspection before being passed for reassembly; place these parts in separate containers from those containing parts for rebuild.
Do not discard a part due for renewal until after
comparing it with a new part, to ensure that its correct replacement has been obtained.
Cleaning components
Always use the recommended cleaning agent or equivalent.
WARNING: Ensure that adequate ventilation is provided when volatile degreasing agents are being used.
CAUTION: Do not use degreasing equipment for components containing items which could be damaged by the use
of this process.
General Inspection
Never inspect a component for wear or dimensional check unless it is absolutely clean; a slight smear of grease can conceal an incipient failure.
When a component is to be checked dimensionally against recommended values, use the appropriate measuring equipment (surface plates, micrometers, dial guages etc.). Ensure the measuring equipment is calibrated and in good serviceable condition.
Reject a component if its dimensions are outside the specified tolerances, or if it appears to be damaged. A part may be refitted if its critcal dimension is exactly to its tolerance limit and it appers to be in satisfactory condition.
Use ’Plastigauge’ 12 Type PG-1 for checking bearing surface clearances.
GENERAL PRECAUTIONS AND FITTING INSTRUCTIONS 5

GENERAL INFORMATION

BALL AND ROLLER BEARINGS

CAUTION: Never refit a ball or roller bearing without first ensuring that it is in a fully serviceable condition.
CAUTION: When hub bearings are removed or displaced, NEW bearings must be fitted; do not attempt to refit the old
hub bearings.
Remove all traces of lubricant from bearing under inspection by cleaning with a suitable degreaser; maintain absolute cleanliness throughout operations.
Conduct a visual inspection for markings on rolling elements, raceways, outer surface of outer rings or inner surface of inner rings. Reject any bearings found to be marked, since marking in these areas indicates onset of wear.
Hold inner race of bearing between finger and thumb of one hand and spin outer race to check that it revolves absolutely smoothly. Repeat, holding outer race and spinning inner race.
Rotate outer ring gently with a reciprocating motion, while holding inner ring; feel for any check or obstruction to rotation. Reject bearing if action is not perfectly smooth.
Lubricate bearing with generous amounts of lubricant appropriate to installation.
Inspect shaft and bearing housing for discoloration or other markings which indicate
movement between bearing and seatings.
Ensure that shaft and housing are clean and free from burrs before fitting bearing.
If one bearing of a pair shows an imperfection, it is advisable to replace both with new bearings; an exception could be if the faulty bearing had covered a low mileage, and it can be established that damage is confined to only one bearing.
When fitting a bearing to a shaft, only apply force to the inner ring of the bearing. When fitting a bearing into a housing, only apply force to the outer ring of the bearing.
In the case of grease lubricated bearings (e.g. hub bearings) fill the space between bearing and outer seal with the recommended grade of grease before fitting seal.
Always mark components of separable bearings (e.g. taper roller bearings) when dismantling, to ensure correct reassembly. Never fit new rollers in a used outer ring; always fit a complete new bearing assembly.

GENERAL INFORMATION

OIL SEALS

Always renew oil seals which have been removed from their working location (whether as an individual component or as part of an assembly).
Carefully examine seal before fitting to ensure that it is clean and undamaged.
Ensure the surface on which the new seal is to run is free of burrs or scratches. Renew the component if the original sealing surface cannot be completely restored.
Protect the seal from any surface which it has to pass when being fitted. Use a protective sleeve or tape to cover the relevant surface.
Lubricate the sealing lips with a recommended lubricant before use to prevent damage during initial use. On dual lipped seals, smear the area between the lips with grease.
If a seal spring is provided, ensure that it is fitted correctly.
Place lip of seal towards fluid to be sealed and slide into position on shaft. Use fitting sleeve where possible to protect sealing lip from damage by sharp corners, threads or splines. If a fitting sleeve is not available, use plastic tube or tape to prevent damage to the sealing lip.
Grease outside diameter of seal, place square to housing recess and press into position using great care, and if possible a ’bell piece’ to ensure that seal is not tilted. Never let weight of unsupported shaft rest in seal.
NOTE: In some cases it may be preferable to fit seal to housing before fitting to shaft.
Use the recommended service tool to fit an oil seal. If the correct service tool is not available, use a suitable tube approximately 0.4 mm (0.015 in.) smaller than the outside diameter of the seal. Use an hammer VERY GENTLY on drift if a suitable press is not available.
Press or drift the seal in to the depth of its housing with the sealing lip facing the lubricant to be retained if the housing is shouldered, or flush with the face of the housing where no shoulder is provided. Ensure that the seal does not enter the housing in a tilted position.
NOTE: Most cases of failure or leakage of oil seals are due to poor fitting, which can
result in damage to both seals and sealing surfaces. NEVER use a seal which has been improperly stored or handled, such as hung on a hook or nail.
GENERAL PRECAUTIONS AND FITTING INSTRUCTIONS 7

GENERAL INFORMATION

JOINTS AND JOINT FACES

Fit joints dry unless specified otherwise.
Always use the correct gaskets as specified.
When jointing compound is used, apply in a thin
uniform film to metal surfaces; take care to prevent jointing compound from entering oilways, pipes or blind tapped holes.
If gaskets and/or jointing compound is recommended for use; remove all traces of old jointing material prior to reassembly. Do not use a tool which will damage the joint faces and smooth out any scratches or burrs using an oil stone. Do not allow dirt or jointing material to enter any tapped holes or enclosed parts.
Prior to reassembly, blow through any pipes, channels or crevices with compressed air.

LOCKING DEVICES

Tab Washers
CAUTION: Always release locking tabs and fit new locking washers, do not re-use locking tabs. Ensure the new tab washer
is the same design as that replaced.
Locking Nuts
Always use a backing spanner when slackening or tightening brake and fuel pipe unions.
Roll Pins
Always fit new roll pins of an interference fit in the hole.
Circlips
Always fit new circlips of the correct size for the groove.
Locking wire
Always fit locking wire of the correct type. Arrange wire so that its tension tends to tighten the bolt heads or nuts to which it is fitted.
Keys and Keyways
Remove burrs from edges of keyways with a fine file and clean thoroughly before attempting to refit key.
Clean and inspect key closely; keys are suitable for refitting only if indistinguishable from new, as any indentation may indicate the onset of wear.
Fitting a split pin
CAUTION: Always fit new split-pins of the correct size for the hole in the bolt or stud. Do not slacken nut to enter split-pin.
8
GENERAL PRECAUTIONS AND FITTING INSTRUCTIONS
Page 18
GENERAL INFORMATION

SCREW THREADS

Metric threads to ISO standards are used. Damaged nuts, bolts and screws must always be
discarded.
NOTE: Cleaning damaged threads with a die or tap impairs the strength and closeness of fit of the threads and is not
recommended.
CAUTION: Always ensure that replacement bolts are at least equal in strength to those replaced.
Castellated nuts must not be slackened to accept a split-pin, except in recommended cases when this forms part of an adjustment.
Do not allow oil or grease to enter blind threaded holes. The hydraulic action on screwing in the bolt or stud could split the housing.
Always tighten a nut or bolt to the recommended torque figure. Damaged or corroded threads can affect the torque reading.
To check or re-tighten a bolt or screw to a specified torque figure, first slacken a quarter of a turn, then retighten to the correct torque figure.
Oil thread lightly before tightening to ensure a free running thread, except in the case of threads treated with sealant / lubricant, and self-locking nuts.

BOLT IDENTIFICATION

An ISO metric bolt or screw made of steel and larger than 6 mm in diameter can be identified by either of the symbols ISO M or M embossed or indented on top of the bolt head.
In addition to marks identifying the manufacturer, the top of the bolt head is also marked with symbols indicating the strength grade, e.g. 8.8; 10.9; 12.9;
14.9. As an alternative, some bolts and screws have
the M and strength grade symbol stamped on the flats of the hexagon.
Encapsulated bolts and screws
Encapsulated bolts and screws have a micro-encapsulated locking agent pre-applied to the thread. They are identified by a coloured section which extends 360° around the thread. The locking agent is released and activated by the assembly process and is then chemically cured to provide the locking action.
GENERAL PRECAUTIONS AND FITTING INSTRUCTIONS 9
Page 19
GENERAL INFORMATION
Unless a specific repair procedure states otherwise, encapsulated bolts may be re-used providing the threads are undamaged and the following procedure is adopted:
Remove loose adhesive from the bolt and housing threads.
Ensure threads are clean and free of oil and grease.
Apply an approved locking agent.
NOTE: Always fit a new encapsulated bolt when replacing; or if not available, a bolt of equivalent specification treated with an
approved locking agent.
Self-locking bolts and screws

NUT IDENTIFICATION

A nut with an ISO metric thread is marked on one face or on one of the flats of the hexagon with the strength grade symbol 8, 12, or 14. Some nuts with a strength grade 4, 5 or 6 are also marked and some have the metric symbol M on the flat opposite the strength grade marking.
Self-locking bolts and screws, i.e. nylon patched or trilobular thread can be re-used providing resistance can be felt when the locking portion enters the female thread.
Nylon patched bolts and screws have a locking agent pre-applied to the threads. They are identified by the presence of a coloured section of thread which extends for up to 180° around the thread.
Trilobular bolts (i.e. Powerlok) have a special thread form which creates a slight interference in the tapped hole or threads of the nut into which it is screwed.
CAUTION: DO NOT re-use self-locking fasteners in critical locations (e.g. engine
bearings, flywheel). Always use the correct replacement self-locking nut, bolt or screw.
A clock face system is sometimes used as an alternative method of indicating the strength grade. The external chamfers or a face of the nut is marked in a position relative to the appropriate hour mark on a clock face to indicate the strength grade.
A dot is used to locate the 12 o’clock position and a dash to indicate the strength grade. If the grade is above 12, two dots identify the 12 o’clock position.
10
CAUTION: DO NOT fit non self-locking
fasteners in applications where a
self-locking nut, bolt or screw is specified.
GENERAL PRECAUTIONS AND FITTING INSTRUCTIONS
Page 20
GENERAL INFORMATION
Self-locking nuts
Self-locking nuts, i.e. nylon insert or deferred thread nuts can be re-used providing resistance can be felt when the locking portion of the nut passes over the thread of the bolt or stud.
CAUTION: Do not apply heat in an attempt
to free deferred thread nuts or fittings; as
well as causing damage to protective coatings, there is a risk of damage to electronic equipment and brake linings from stray heat.
When tightening a slotted or castellated nut, never loosen it to insert a split pin or locking wire except where recommended as part of an adjustment. If difficulty is experienced, alternative washers or nuts should be selected, or the washer thickness reduced.
Where self-locking nuts have been removed, it is advisable to replace them with new ones of the
same type.

FLEXIBLE HYDRAULIC PIPES AND HOSES

WARNING: Do not disconnect any pipes in an air conditioning refrigeration system
unless trained and instructed to do so. A refrigerant is used which can cause blindness if allowed to contact eyes.
Before removing any brake or power steering
hose, clean end fittings and area surrounding them as thoroughly as possible.
Obtain appropriate plugs or caps before
detaching hose end fittings, so that the ports can be immediately covered to prevent the ingress of dirt.
Clean hose externally and blow through with
airline. Examine carefully for cracks, separation of plies, security of end fittings and external damage. Reject any faulty hoses.
When refitting a hose, ensure that no
unnecessary bends are introduced, and that hose is not twisted before or during tightening of union nuts.
Fit a cap to seal a hydraulic union and a plug to
its socket after removal to prevent ingress of dirt.
Absolute cleanliness must be observed with
hydraulic components at all times.
After any work on hydraulic systems, carefully
inspect for leaks underneath the vehicle while a second operator applies maximum brake pressure to the brakes (engine running) and operates the steering.
NOTE: Where bearing pre-load is involved nuts should be tightened in accordance with special instructions.
GENERAL PRECAUTIONS AND FITTING INSTRUCTIONS 11
Page 21
GENERAL INFORMATION
Fuel System Hoses
CAUTION: All fuel hoses are made up of two laminations, an armoured rubber
outer sleeve and an inner viton core. If any of the fuel system hoses have been disconnected, it is imperative that the internal bore is inspected to ensure that the viton lining has not become separated from the armoured outer sleeve. A new hose must be fitted if separation is evident.

DYNAMOMETER TESTING - NON ANTI-LOCK BRAKE VEHICLES

The front and rear wheels cannot be driven independently due to the viscous coupling. This eliminates the need for differential lock by progressively applying more torque to the rear wheels if the front wheels start to slip.
WARNING: DO NOT attempt to drive individual wheels with vehicle supported on floor jacks or stands.
Four wheel dynamometers
Provided that front and rear dynamometer rollers are rotating at identical speeds and that normal workshop safety standards are applied, there is no speed restriction during testing, except any that may apply to the tyres.
Two wheel dynamometers
IMPORTANT: Use a four wheel dynamometer for brake testing if possible.

SERVICE TOOLS AND GARAGE EQUIPMENT

Special service tools have been developed to facilitate removal, dismantling and assembly of
mechanical components in a cost effective and time efficient manner. The use of such special tools also helps prevent the potential for damage to components. Some operations described in this Manual cannot be carried out properly without the aid of the relevant service tools.
Where specific garage equipment is required for diagnosis and repair, reference should be made to the Service Tools and Equipment Programme where details of the equipment recommended by Land Rover Service may be found.
If brake testing on a single rig is necessary, the following procedures should be ensured:
propeller shaft to the rear axle is removed
neutral selected in gearbox
hill descent control not selected.
When checking brakes, run engine at idle speed to maintain servo vacuum.

GENERAL INFORMATION

FUEL HANDLING PRECAUTIONS

General
The following information provides basic precautions which must be observed if petrol (gasoline) is to be handled safely. It also outlines other areas of risk which must not be ignored. This information is issued for basic guidance only, if in doubt consult your local Fire Officer.
Petrol - Gasoline
Petrol/gasoline vapour is highly flammable and in confined spaces is also explosive and toxic.
When petrol/gasoline evaporates it produces 150 times its own volume in vapour, which when diluted with air becomes a readily ignitable mixture. The vapour is heavier than air and will always fall to the lowest level. The vapour can be easily distributed throughout a workshop by air currents; consequently, even a small spillage of petrol/gasoline is potentially very dangerous.
WARNING: Do not use a pit when
removing fuel system components.
Always have a fire extinguisher containing FOAM, CO2, GAS or POWDER close at hand when handling or draining fuel or when dismantling fuel systems. Fire extinguishers should also be located in areas where fuel containers are stored.
Always disconnect the vehicle battery before carrying out dismantling or draining work on a fuel system.
Fuel tank drainage
WARNING: Petrol/gasoline must not be extracted or drained from any vehicle
whilst it is standing over a pit. Draining or extraction of petrol/gasoline from a vehicle fuel tank must be carried out in a well ventilated area. The receptacle used to contain the petrol/gasoline must be more than adequate for the full amount of fuel to be extracted or drained. The receptacle should be clearly marked with its contents, and placed in a safe storage area which meets the requirements of local authority regulations.
WARNING: When petrol/gasoline has been
extracted or drained from a fuel tank the
precautions governing naked lights and ignition sources should be maintained.
Fuel tank removal
When the fuel line is secured to the fuel tank outlet by a spring steel clip, the clip must be released before the fuel line is disconnected or the fuel tank is removed. This procedure will avoid the possibility of residual petrol fumes in the fuel tank being ignited when the clip is released.
As an added precaution fuel tanks should have a ’PETROL (GASOLINE) VAPOUR’ warning label attached to them as soon as they are removed from the vehicle.
Whenever petrol/gasoline is being handled, drained or stored, or when fuel systems are being dismantled, all forms of ignition must be extinguished or removed; any leadlamps must be flameproof and kept clear of spillage.
WARNING: No one should be permitted to repair components associated with petrol/gasoline without first having
specialist training.

FUEL HANDLING PRECAUTIONS 1

Page 25
GENERAL INFORMATION
Fuel tank repairs
Under no circumstances should a repair to any fuel tank be carried out without first rendering the tank SAFE, by using one of the following methods:
a. STEAMING: With the filler cap and tank unit removed, empty the tank. Steam the tank for at least two hours with low pressure steam. Position the tank so that condensation can drain away freely, ensuring that any sediment and sludge not volatized by the steam is washed out during the steaming process.
b. BOILING: With the filler cap and tank unit removed, empty the tank. Immerse the tank completely in boiling water containing an effective alkaline degreasing agent or a detergent, with the water filling and also surrounding, the tank for at least two hours.
After steaming or boiling, a signed and dated label to this effect should be attached to the tank.
Body repairs
WARNING: When body repairs involve the use of heat, all fuel pipes which run in the
vicinity of the repair area must be removed, and the tank outlet plugged, BEFORE HEAT IS APPLIED. If the repair is in the vicinity of the fuel tank, the tank must be removed.
Plastic fuel pipes are particularly susceptible to heat,
even at relatively low temperature, and can be melted by heat conducted from some distance away.
Fuel lines or tanks must not be removed whilst the vehicle is over an inspection pit.

GENERAL INFORMATION

ELECTRICAL PRECAUTIONS

General
The following guidelines are intended to ensure the safety of the operator whilst preventing damage to the electrical and electronic components fitted to the vehicle. Where necessary, specific precautions are detailed in the relevant sections of this Manual which should be referred to prior to commencing repair operations.
Equipment
Prior to commencing any test procedure on the vehicle ensure that the relevant test equipment is working correctly and any harness or connectors are in good condition. It is particularly important to ensure the propriety of the lead and plugs of mains operated equipment.
Polarity
Never reverse connect the vehicle battery and always ensure the correct polarity when connecting test equipment.
High Voltage Circuits
Whenever disconnecting live ht-circuits always use insulated pliers and never allow the open end of the ht-lead to contact other components - particularly ECU’s.
CAUTION: Exercise caution when
measuring the voltage on the coil
terminals while the engine is running, high voltage spikes can occur on these terminals.
Connectors and Harnesses
The engine compartment of a vehicle is a particularly hostile environment for electrical components and connectors. Always ensure electrically related items are dry and oil free before disconnecting and connecting test equipment.
Ensure that any protection (covers, insulation etc.) is replaced if disturbed.
Having confirmed a component to be faulty:
switch off the ignition and disconnect the battery.
remove the component and support the
disconnected harness.
when replacing the component keep oily hands away from electrical connection areas and push connectors home until any locking tabs fully engage.
Battery disconnection
Before disconnecting the battery, disable the alarm system and switch off all electrical equipment. If the radio is to be serviced, ensure the security code has been deactivated.
CAUTION: To prevent damage to electrical components ALWAYS disconnect the
battery when working on the vehicle electrical system. The earth lead must be disconnected first and reconnected last. Always ensure that battery leads are routed correctly and are not close to any potential chafing points.
Battery charging
Only recharge the battery with it removed from the vehicle.
Always ensure any battery charging area is well ventilated and that every precaution is taken to avoid naked flames and sparks.
CAUTION: Ensure disconnected multiplugs and sensors are protected from
being contaminated with oil, coolant or other solutions. Contamination could impair performance or result in catastrophic failure.
Never force connectors apart using tools to prise apart or by pulling on the wiring harness.
Always ensure locking tabs are disengaged before disconnection, and match orientation to enable correct reconnection.

GENERAL INFORMATION
Ignition system safety precautions
WARNING: Before commencing work on
an ignition system, all high tension
terminals, adapters and diagnostic equipment should be inspected.
Ensure all cables, connectors and components are adequately insulated and shielded. Accidental contact with a poorly insulated ignition system component could result in a severe electrical shock.
Wearers of surgically implanted pacemaker devices should not be in close proximity to ignition circuits or diagnostic equipment.
Disciplines
Switch off the ignition prior to making any connection or disconnection in the system to prevent electrical surges caused by disconnecting ’live’ connections damaging electronic components.
Grease for electrical connectors
Some under bonnet and under body connectors may be protected against corrosion by the application of a special grease during vehicle production. Should connectors be disturbed in service, or repaired or replaced, additional grease should be re-applied: Part No. BAU 5811, available in 150 gm tubs.
NOTE: The use of greases other than BAU 5811 must be avoided as they can migrate
into relays, switches etc. contaminating the contacts and leading to intermittent operation or failure.
Ensure hands and work surfaces are clean and free of grease, swarf, etc. Grease collects dirt which can cause electrical tracking (short-circuits) or high-resistance contacts.
When handling printed circuit boards, treat with care and hold by the edges only; note that some electronic components are susceptible to body static.
Connectors should never be subjected to forced removal or refit, especially inter-board connectors. Damaged contacts can cause short-circuit and open-circuit fault conditions.
Prior to commencing test, and periodically during a test, touch a good vehicle body earth to discharge static charge. Some electronic components are vulnerable to the static electricity that may be generated by the operator.

SUPPLEMENTARY RESTRAINT SYSTEM PRECAUTIONS

General
The Supplementary Restraint System (SRS) provides active protection for vehicle occupants in the event of a serious collision. The system components include airbags and pre-tensioner seatbelts which are automatically deployed when a severe frontal crash condition is detected.
WARNING: Do not use rear facing child seats in the front passenger seat if the vehicle is fitted with a passenger airbag.
In order to assure system integrity, it is essential that the SRS system is regularly checked and maintained so that it is ready for operation in the event of an accident.
The SRS system contains components which could be potentially hazardous to the service engineer if not serviced and handled correctly. The following guidelines are intended to alert the service engineer to potential sources of danger and emphasise the importance of ensuring integrity of the SRS components fitted to the vehicle.
It should be noted that these precautions are not restricted to operations performed when servicing the SRS system, the same care should be exercised when working on ancilliary systems and components located in the vicinity of SRS components; these include but are not limited to steering system (steering wheel airbag), body and trim components (passenger airbag and seat belt pre-tensioners) and electrical system components (SRS harnesses etc.).
WARNING: Always follow the Safety
Guidelines and correct procedures for
working on SRS components.
NOTE: Airbag modules should be replaced
every ten years.
Where necessary, additional specific precautions are detailed in the relevant sections of this Manual which should be referred to prior to commencing repair operations.

SRS PRECAUTIONS 1

Page 29
GENERAL INFORMATION
Preliminary Procedures
WARNING: Always remove the ignition key from the starter switch, disconnect the vehicle battery and wait 10 minutes before
and commencing work on the SRS system.
The SRS system uses energy reserve capacitors that keep the system active in the event of electrical supply failure under crash conditions. It is necessary to allow the capacitor sufficient time to discharge (10 minutes) in order to avoid the risk of accidental deployment.
CAUTION: Always disconnect both battery leads before beginning work on the SRS
system. Disconnect the negative battery cable first. Never reverse connect the vehicle battery and always ensure the correct polarity when connecting test equipment.
CAUTION: Always disconnect the vehicle
battery before carrying out any electric
welding on a vehicle fitted with an SRS system.

AIR CONDITIONING SYSTEM PRECAUTIONS

General
The air conditioning system contains fluids and components which could be potentially hazardous to the service engineer or the environment if not serviced and handled correctly. The following guidelines are intended to alert the service engineer to potential sources of danger and emphasise the importance of ensuring the integrity of the Air Conditioning operating conditions and components fitted to the vehicle.
Where necessary, additional specific precautions are detailed in the relevant sections of this Manual which should be referred to prior to commencing repair operations.
The refrigerant used in the air conditioning system is HFC-134a (Hydrofluorocarbon) R134a.
WARNING: The air conditioning system is charged with a high pressure, potentially
toxic refrigerant. Repairs or servicing must only be carried out by a trained operator familiar with both the vehicle system and the charging and testing equipment.
WARNING: All operations pertaining to the
air conditioning system must be carried
out in a well ventilated area. Always observe the following precautions:
R134a is odourless and colourless. Do not
handle or discharge in an enclosed area, or any area where the vapour and liquid can come into contact with a naked flame or hot metal. R134a is not flammable, but it can cause a highly toxic gas.
Do not smoke or weld in areas where R134a
is in use.
Inhalation of concentrations of vapour can
cause dizziness, disorientation, incoordination, narcosis, nausea or vomiting.
Refrigerant R134a from domestic and
commercial sources must not be used in motor vehicle air conditioning systems.
WARNING: HFC-134a (R134a) is a hazardous liquid which if handled
incorrectly can cause serious injury. The following precautions should be adhered to at all times when working on an air conditioning system:
Suitable protective clothing must be worn
when carrying out service operations on the air conditioning system.
Air conditioning connections should be
opened carefully to allow any liquid or pressure to bleed off slowly.
Do not allow a refrigerant container to be
heated by direct flame or to be placed near any heating appliance. A refrigerant container must not be heated above 50°C.
Do not leave a refrigerant container without
its cap fitted.
Do not transport a refrigerant container that
is unrestrained (especially in the luggage compartment of a car).
Do not allow fluids, other than R134a or
compressor lubricant, to enter the air conditioning system; spontaneous combustion could occur.
R134a splashed onto exposed skin will cause
immediate freezing of that area.
Refrigerant cylinders and replenishment
trolleys can become cooled when discharging, this could cause skin to become frozen to them if contact is made.
The refrigerant used in an air conditioning
system must be reclaimed in accordance with the recommendations stipulated by a Refrigerant Recovery, Recycling & Recharging Station.

AIR CONDITIONING PRECAUTIONS 1

Page 39
GENERAL INFORMATION
Protective Clothing
NOTE: Suitable protective clothing comprises:
Wrap round safety glasses or helmet
Heat proof gloves
Rubber apron, or waterproof overalls
Rubber boots.

REMEDIAL ACTIONS

If an accident involving R134a should occur, conduct the following remedial actions:
If liquid R134a enters the eye, do not rub it.
Gently run large quantities of eye wash over affected eye to raise the temperature. If an eye wash is not available, cool, clean water may be used to flush the eye. After rinsing, cover the eye with a clean pad and seek immediate medical attention.
If liquid R134a is splashed onto the skin, run
large quantities of water over the affected area to raise the temperature. Implement the same action if the skin comes in contact with discharging cylinders. Wrap the contaminated body parts in blankets (or similar materials) and seek immediate medical attention.
If the debilitating effects of inhalation of R134a
vapour is suspected, seek fresh air. If the affected person is unconscious, move them away from the contaminated area to fresh air and apply artificial respiration and/or oxygen and seek immediate medical attention.
WARNING: Due to its low evaporating
temperature of -30°C, R134a should be
handled with extreme care.

AIR CONDITIONING PRECAUTIONS
Page 40
GENERAL INFORMATION

SERVICE PRECAUTIONS

CAUTION: Observe the following precautions when handling components used in the air conditioning system:
Air conditioning units must not be lifted by their hoses, pipes or capillary lines.
Hoses and lines must not be subjected to any twist or stress - the efficiency of the system will be impaired by kinks or restrictions. Ensure that hoses are correctly positioned before tightening couplings, and ensure that all clips and supports are utilised.
Flexible hoses should not be postioned close to the exhaust manifold (less than 100mm) unless protected by heat shielding.
Completed assemblies must be checked for refrigeration lines touching metal panels. Any direct contact of components and panels may transmit noise and so must be eliminated.
The appropriate torque wrench must be used when tightening refrigerant connections to the stipulated value. An additional spanner must be used to hold the union to prevent twisting of the pipe when tightening connections.
Before connecting any hose or pipe, ensure that refrigerant oil is applied to the seat of the new ’O’ ring seals, BUT NOT to the threads of the connection.
All protective plugs must remain in place to
seal the component until immediately prior to connection.
Ensure components are at room temperature before uncapping, to prevent condensation of moisture from the air that enters it.
Components must not remain uncapped for longer than 15 minutes. In the event of a delay, the caps must be fitted.
When disconnecting, immediately cap all air conditioning pipes to prevent ingress of dirt and moisture into the system.
The receiver/dryer contains desiccant which absorbs moisture. It must be positively sealed at all times. A receiver/drier that has been left uncapped must not be used, fit a new unit.
The receiver/drier should be the last component connected to the system to ensure optimum dehydration and maximum moisture protection of the system.
Whenever the refrigerant system is opened, the receiver/dryer must be renewed immediately before evacuating and recharging the system.
Use alcohol and a clean lint-free cloth to clean dirty connections.
Ensure that all new parts fitted are marked for use with R134a.
When a major repair has been completed, a leak test should be conducted; refer to the air conditioning section of this manual for the correct procedure.
AIR CONDITIONING PRECAUTIONS 3
Page 41
GENERAL INFORMATION
Refrigerant oil
Use an approved refrigerant lubricating oil: ND Oil 8
CAUTION: Do not use any other type of refrigerant oil.
CAUTION: Refrigerant oil easily absorbs water and must not be stored for long periods. Do not pour unused oil back into
the container.
When renewing system components, add the quantities of refrigerant oil recommended in the Air Conditioning section of this manual.
Compressor
A new compressor is sealed and pressurised with Nitrogen gas. When fitting a new compressor, slowly release the sealing cap; gas pressure should be heard to vent as the seal is broken.
Rapid refrigerant discharge
CAUTION: If the air conditioning system is involved in accident damage and the
system is punctured, the refrigerant will discharge rapidly. The rapid discharge of refrigerant will also result in the loss of most of the oil from the system. The compressor must be removed and all the remaining oil in the compressor drained and refilled as instructed in the air conditioning section of this manual.
CAUTION: A new compressor should always have its sealing cap in place and
must not be removed until immediately prior to fitting the compressor air conditioning pipes.

PRECAUTIONS FOR REFRIGERANT RECOVERY, RECYCLING AND RECHARGING

WARNING: Refrigerant must always be
recycled before reuse to ensure that the
purity of the refrigerant is high enough for safe use in the air conditioning system.
WARNING: Recycling should always be
carried out with equipment which is
design certified by Underwriter Laboratory Inc. for compliance with SAE-J1991. Other equipment may not recycle refrigerant to the required level of purity.
A R134a Refrigerant, Recovery, Recycling and Recharging Station must not be used with any other type of refrigerant.
CAUTION: When using an air conditioning
portable Refrigerant, Recovery, Recycling
and Recharging Station the operator must adhere to the equipment manufacturer’s instructions.
GENERAL INFORMATION
CAUTION: The system must be evacuated
immediately before recharging

ELECTRONIC CONTROL UNITS

The electronic control units (ECU) fitted to vehicles make it advisable to follow suitable precautions prior to carrying out welding repair operations. Harsh conditions of heat and vibration may be generated during these operations which could cause damage to the units.
Electrical precautions.
In particular, it is essential to follow the appropriate precautions when disconnecting or removing the airbag ECU.

BODY REPAIRS

General
Body shells are of monocoque construction. Front and rear sections of the shell are designed as ’energy absorbing’ zones. This means they are designed to deform progressively when subjected to impact in order to minimise the likelihood of injury to vehicle occupants.
It is essential that design dimensions and strength are restored in accident rectification. It is important that neither structural weakness nor excessive local stiffness are introduced into the vehicle during body repair.
Repairs usually involve a combination of operations ranging from straightening procedures to renewal of individual panels or panel assemblies. The repairer will determine the repair method and this decision will take into account a balance of economics between labour and material costs and the availability of repair facilities in both equipment and skills. It may also involve considerations of the vehicles’ downtime, replacement vehicle availability and repair turn-around time.
Body repairs often involve the removal of mechanical and electrical units and associated wiring. Where necessary, refer to the relevant section of the Workshop Manual for removal and refitting instructions. Component removal and refitting instructions for the BODY and SRS sections are also included in this Manual.
Body components
Taking into consideration the differences in body styles, suspension systems and engine and transmission layouts, the location of the following components as applicable to a particular vehicle is critical:
Front suspension upper damper mountings.
Front suspension or sub frame mountings.
Rear suspension upper damper mountings.
Rear suspension mountings or lower pivots.
Additional points which can be used to check alignment and assembly are:
Inner holes in crossmember - side - main floor.
Holes in front longitudinals.
Holes in side member.
Holes in rear longitudinals.
Holes in rear lower panels or extension rear floor.
It is expected that a repairer will select the best and most economic repair method possible, making use of the facilities available. The instructions given are intended to assist a skilled body repairer by expanding approved procedures for panel replacement. The objective is to restore the vehicle
to a safe running condition by carrying out a repair which is as close as is feasible to original standard. The results should not advertise to the experienced eye that the vehicle has been damaged, although the repair might not be identical in all respects to the original factory build. Commercial bodyshop repair facilities cannot always duplicate methods of construction used during production.
Operations covered in this Manual do not include reference to testing the vehicle after repair. It is essential that work is inspected and suspension geometry checked after completion. Where necessary a road test of the vehicle should be carried out, particularly where safety-related items are concerned.
Where major units have been disconnected or removed it is necessary to ensure that fluid levels are checked and topped up where necessary. It is also necessary to ensure that the repaired vehicle is in a roadworthy condition in respect of tyre pressures, lights, washer fluid etc.
Apertures for windscreen, backlight, bonnet and doors can be measured and checked using the dimensional information provided and also by offering up an undamaged component as a gauge.

BODY REPAIRS 1

Page 59
INFORMATION
Straightening
Whenever possible, structural members should be cold straightened under tension. Do not attempt to straighten with a single pull but rework the damaged area using a series of pulls, releasing tension between each stage and using the opportunity to check alignment.
Body jig
Unless damage is limited to cosmetic panels, all repair work to body members must be carried out on a body jig, to ensure that impact damage has not spread into more remote parts of the structure. Mounting on a jig will also ensure that the straightening and panel replacement procedures do not cause further distortion.
If original dimensions cannot be satisfactorily restored by these methods, damaged structural members should be replaced. Damaged areas should be cut away using a high speed saw, NOT an oxy-acetylene torch.
As a rule, body dimensions are symmetrical about the centre line. A good initial check for distortion is therefore to measure diagonally and to investigate apparent differences in dimensions.
Inspection
Every accident produces individual variations in damage. Each repair is influenced by the extent of
the damage and the facilities and equipment available for its rectification.
Most accident damage can be visually inspected and the approximate extent of damage assessed. Sometimes deformation will extend beyond the directly damaged area, and the severity of this must be accurately established so that steps can be taken to restore critical body components to their original dimensions. An initial check can be carried out by means of drop checks or, preferably, trammels. Gauges are available which will accurately check for body twist.

DIMENSIONAL INFORMATION

The following dimensional information is shown so as to assist the technician in the diagnosis and repair of body panels. The information is shown in two different ways. There are X,Y,Z dimensions and actual point to point dimensions.
The X,Y,Z dimensions are the measuring planes used within Rover Group for the measurement of body panels. The whole bodyshell is within a parallel grid system.
The X plane is an imaginary vertical line starting at the front of the vehicle. It is parallel to the body and measures the length of the vehicle.
The Y plane is an imaginary line through the center of the vehicle. All Y dimensions start from this line. As a rule, body dimensions are symmetrical about the centre line.
INFORMATION
The Z plane is set at a fixed distance parallel and perpendicular to the underside of the vehicle. All Z dimensions start from this plane.
The point to point measurements are actual distances between two points. These points can be holes or intersection points. Where holes are taken, the point of measurement is always from the hole centre.
All measurements shown are in millimetres.

INFORMATION
When re-treating wax-injected areas which have been disturbed during repairs, it is necessary to use a compressed air spray gun with integral pressure cup and a selection of interchangeable lances.
The following points must be observed during use, according to the attachments fitted:
Use the rigid or flexible lance attachments with 360° spray dispersal when treating enclosed areas, to ensure maximum coverage.
Where openings are restricted, use the hook nozzle to provide a more directional spray (e.g. inside narrow or short box sections).
Spray exposed underbody surfaces directly from the gun less lance attachment and without disconnecting the fluid coupling.
1100mm rigid lance
The nozzle on the rigid lance produces a 360° circular spray pattern combined with a forward-directed spray. Although wax is distributed to all box section surfaces in a single stroke, effective and complete coverage is obtained in long straight structures and box section cavities by spraying on both inward and outward strokes of the lance.
Hook nozzle on flexible lance
The rigid hook produces a highly atomised, forward-directed, fully conical spray pattern having long range and good dispersion characteristics. This combination has good directional capabilities for treating short, narrow sections, and may also be used for direct spraying of inner wheel arches etc.
In use, position the flat area at the end of the lance at 180° to the nozzle spray direction. This will help to guide the spray more accurately when it is concealed in a box section or access hole.
For general spraying, move the nozzle in an arc from side to side as required, to ensure full coverage.
NOTE: Ensure that all wax injection/application equipment is kept clean. Use white spirit for this purpose
immediately after wax injection operations.
The rigid lance also provides the positional accuracy required in shaped sections, by allowing visual assessment.
CAUTION: Do not force the lance into access holes when using this attachment.
1100mm flexible nylon lance
This lance is similar in pattern to the rigid version, but provides the additional penetration required for curved sections or in places where access is difficult. Its main limitation is a lack of positional accuracy inside box sections.
Carry out all spraying on the outward stroke of the lance. Withdraw the lance slowly to ensure sufficient coverage. Do not withdraw the lance too quickly.
Ensure that the nylon tube of the lance is kept away from the edges of the access hole to eliminate abrasion and extend the life of the tube. Take care to ensure that spraying ceases just before the nozzle emerges from the access hole. To assist in this process paint the final 30mm of the nozzle with RED paint.

WATER LEAKS

Where water leakage is involved, always adopt a logical approach to the problem using a combination of skill, experience and intuition. Do not reach a conclusion based only on visual evidence, such as assuming that a wet footwell is caused by a leak emanating from the windscreen. It will often be found that the source of the leak is elsewhere. Use of the correct procedure will increase the chance of locating a leak, however obscure it may seem.
Tools and equipment
The following tools and equipment are recommended for the purpose of detection and rectification of water leaks:
1. Garden sprayer (hand-operated).
2. Wet/dry vacuum cleaner.
3. Dry, absorbent cloths.
4. Battery torch.
5. Small mirror.
6. Weatherstrip locating tool.
7. Trim panel remover.
8. Small wooden or plastic wedges.
9. Dry compressed air supply.
10. Hot air blower.
11. Sealer applicators.
12. Ultrasonic leak detector.
During leak detection, the vehicle should be considered in three basic sections:
The front interior space.
The rear passenger space.
The loadspace or boot.
Testing
From the information supplied by the customer it should be possible for the bodyshop operator to locate the starting point from which the leak may be detected. After the area of the leak has been identified, find the actual point of entry into the vehicle.
The sequence of testing is particularly important. Start at the lowest point and work slowly upwards, to avoid testing in one area while masking the leak in another. For example, if testing started at the level of the windscreen, any water cascading into the plenum chamber could leak through a bulkhead grommet and into the footwells. Even at this point it could still be wrongly assumed that the windscreen seal was at fault.
Another important part of identifying a water leak is by visual examination of door aperture seals, grommets and weatherstrips for damage, deterioration or misalignment, together with the fit of the door itself against the seals.
Sealing
When the point of the leak has been detected, it will then be necessary to rectify it using the following procedure:
1. Renew all door aperture seals and weatherstrips which have suffered damage, misalignment or deterioration.
2. Check all body seals to ensure that they are correctly located on their mounting flanges/faces using a lipping tool if necessary.
3. Dry out body seams to be treated using compressed air and/or a hot air blower as necessary.
4. Apply sealant on the outside of the joint wherever possible to ensure the exclusion of water.
5. When rectifying leaks between a screen glass and its weatherstrip (or in the case of direct glazing, between the glass and bodywork), avoid removing the glass if possible. Apply the approved material at the appropriate location (i.e. glass to weatherstrip or glass to body).
A simple and effective means in the first instance is an ordinary garden spray with provision for pressure and jet adjustment, which will allow water to be directed in a jet or turned into a fine spray. Use a mirror and a battery-powered torch (NOT a mains voltage inspection lamp) to see into dark corners.

SUPPLEMENTARY RESTRAINT SYSTEM (SRS)

Precautions
Making the system safe
Before working on, or in the area of, the SRS, make the system safe as follows:
1. Remove the key from ignition switch.
2. Disconnect both battery leads, earth lead first.
3. Wait 10 minutes to allow the SRS back-up power to fully discharge.
General
Carefully inspect SRS parts before installation. Do not install a part that shows signs of being dropped or improperly handled, such as dents, cracks or deformation.
The airbag ECU is a shock sensitive device and must be handled with extreme care. Because the crash sensor is incorporated inside the airbag ECU, it is imperative that the bolts securing the airbag ECU and its bracket are tightened to their correct torque.
When carrying an airbag module, hold it by the cover, with the cover uppermost and the base away from your body. Do not wrap your arms around the module.
Do not try to disassemble an airbag module or seat belt pretensioner. They have no serviceable parts and, once deployed, cannot be repaired or reused.
Do not expose an airbag module or seat belt pretensioner to heat exceeding 85°C/185°F) or allow it to be contaminated with oil, grease, detergent or water.
For temporary storage of an airbag module or seat belt pretensioner during service, place in a designated storage area or, if no designated storage area is available, in the loadspace of the vehicle; always lock the vehicle and inform the workshop supervisor.
Airbag modules and seat belt pretensioners are classed as explosive articles. For overnight and longer term storage, they must be stored in an approved, secure steel cabinet which has been registered by the local authority.
Do not install used SRS parts from another vehicle. When repairing a SRS, use only new parts.
Always use new fixings when replacing SRS parts. Do not use a multimeter or other general test
equipment to check SRS parts or connectors.
After completing work, check that the electrical connectors are installed correctly.
Handling and storage
WARNING: If the airbag is improperly stored face down, accidental deployment could propel the unit with enough force to
cause serious injury.
CAUTION: Improper handling or storage can internally damage the airbag module,
making it inoperative. If you suspect the airbag module has been damaged, install a new unit and refer to the Workshop Manual for Deployment/Disposal Procedures.
Do not allow anything to rest on an airbag module.

SRS wiring
Never attempt to modify, splice or repair SRS wiring. Never install electronic equipment such as a mobile
telephone, two way radio or in car entertainment system in such a way that it interferes electrically with the SRS wiring.
Always ensure SRS wiring is routed correctly. Be careful to avoid trapping or pinching the SRS wiring. Ensure the are no possible chafing points.
Always use specified earth fixings tightened to the correct torque. Poor earthing can cause intermittent problems that are difficult to diagnose.
Ensure all SRS wiring connectors are mated correctly and securely fastened. Do not leave the connectors hanging loose.
Warning labels

DESCRIPTION AND OPERATION
Page 90
RESTRAINT SYSTEMS
The SRS is an electronically controlled, single point sensing system. The system comprises an airbag Electronic Control Unit (ECU), a driver’s airbag module, a passenger’s airbag module (optional), two seat belt pretensioners and a warning lamp. Interconnecting wiring for the system is contained in yellow sleeving and integrated into the vehicle harnesses. A rotary coupler connects the vehicle harness to the driver’ airbag module. On vehicles with a passenger’s airbag module, a link lead connects the module to the vehicle harness. An ISO 9141 K line (bi-directional) serial communication link connects the airbag ECU to the vehicle’s diagnostic socket.
SRS schematic
The system is operational only while the ignition is on. With the ignition on, any frontal collision is detected by the airbag ECU. If the impact is above the preset severity, the ECU sends out simultaneous fire signals to the airbag modules and the seat belt pretensioners. The airbag modules then deploy protective airbags in front of the driver and front seat passenger, and the seat belt pretensioners retract to tighten the front seat belts. Collision detection to full deployment of the airbags and pretensioners takes approximately 45 milliseconds.
WARNING: All the SRS parts, including the wiring harness, link lead (where fitted) and rotary coupler, must be renewed after the
airbags and pretensioners have deployed.

Airbag ECU
The airbag ECU controls the operation of the system and also contains the collision detection sensors. The airbag ECU is attached to a bracket on the transmission tunnel, directly below the heater. A vehicle earth output connects to one of the fixings. A 30 pin connector provides the airbag ECU connection with the vehicle harness.
Incorporated into the airbag ECU is a mechanical safing sensor, an electronic single point sensor and integrated circuits for control and diagnostics. The mechanical safing sensor is a normally open switch that closes at the preset deceleration limit. The single point sensor is an accelerometer that produces an output proportional to the vehicle’s deceleration .
Airbag ECU
Power back-up
The airbag ECU incorporates capacitors to ensure the system will function if the external power supply is disconnected during a collision:
A hardware capacitor provides power for 200 milliseconds to enable system operation and collision recording.
Individual capacitors for each fire signal output provide power for 150 milliseconds.
The capacitors are kept charged while the ignition is on by a dc-dc voltage converter incorporated into the airbag ECU. It can take up to 10 minutes from the ignition being switched off for the energy stored in the capacitors to fully dissipate and make the system inert.

DESCRIPTION AND OPERATION
Page 92
RESTRAINT SYSTEMS
Operation
When the ignition is switched on, the airbag ECU performs a bulb check of the SRS warning lamp as part of the power up procedure. The lamp should be extinguished after approximately 5 seconds, indicating that the system is fully operational. If the lamp remains illuminated, a fault has been detected and repair action is required.
While the ignition is on, data from the single point sensor is continuously monitored by the airbag ECU. If the data from the single point sensor indicates vehicle deceleration is at or above the preset limit, and the mechanical safing sensor is closed, the ECU interprets this as a collision that requires deployment of the airbags and retraction of the seat belt pretensioners. It then activates transistors to send fire signals to the airbag modules and the seat belt pretensioners. Simultaneously, the airbag ECU records in memory the following information:
The error code of the last permanent fault (if any) detected before the collision.
Internal program information about the collision as seen by the airbag ECU.
The diagnostic status of the airbag and seat belt pretensioner circuits before deployment.
The voltage of each power backup capacitor before deployment.
Information on the airbag ECU internal program status.
If external power is lost during the collision, recording of the last three above items only occurs if
there is sufficient power in the backup capacitors after outputting the fire signals.
Diagnostics
While the ignition is on the diagnostic function of the airbag ECU monitors the SRS for faults. If a fault is detected, the airbag ECU stores a related fault code in memory and switches the earth output to illuminate the SRS warning lamp. With a supply voltage range fault, the warning lamp is illuminated only for the duration of the fault. With all other faults, including intermittent faults, the warning lamp is illuminated for the remainder of the drive cycle. At the next ignition on, if the fault is still present the warning lamp remains illuminated after the lamp check; if the fault does not recur, the warning lamp extinguishes but the fault code remains stored in memory. An intermittent fault will be cleared from memory if 40 drive cycles are completed without its recurrence.
After detecting a fault, the system may retain some operational capability:
If a fault is detected in an airbag or pretensioner circuit, only that circuit is disabled; the other airbag and pretensioner circuits remain operational and their related components will still be deployed in a collision.
If an internal or power supply fault is detected, the complete system will be disabled.
If a fault exists in the SRS warning lamp circuit, the lamp will not illuminate during the lamp check at ignition on, but, provided there are no other faults, the system will otherwise be fully operational.
When deployment and collision event recording has been completed, the airbag ECU enters crash locked mode and illuminates the SRS warning lamp. In crash locked mode the airbag ECU is permanently disabled and must be replaced during subsequent repair action. Crash locked mode cannot be cleared using Testbook.
DESCRIPTION AND OPERATION 9

RESTRAINT SYSTEMS
Fault code retrieval and fault diagnosis of the SRS can only be done using Testbook. Additional SRS information that can be read using Testbook is the:
Airbag ECU bar code.
Evolution number of the hardware, software and
diagnostic protocol.
Status of the crash locked mode.
Vehicle identification number (VIN) data.
Diagnostic checks performed by the airbag ECU include:
Monitoring of the airbag and pretensioner circuits for open/short circuits.
Internal errors.
Supply voltage (limits are 8.6 to 19.0 V at power
up, 6.0 to 19.0 V during drive cycle).
Airbag modules
During a frontal collision each airbag module deploys a gas filled bag to form a protective cushion between the front seat occupant and the steering wheel or fascia/windshield. The driver’s airbag module is attached to the centre of the steering wheel. Where fitted, the passenger’s airbag module is installed in the fascia, above the glovebox.
Each airbag module has a gas generator attached to a folded airbag installed in a housing. The driver’s airbag has an inflated volume of 45 litres; the passenger’s airbag has an inflated volume of 120 litres. The gas generator of the driver’s airbag module is filled with a nitrocellulose based material; the gas generator of the passenger’s airbag module is filled with a sodium azide based material. The outlet of the gas generators incorporates a filter screen to prevent solid combustion by-products entering the airbag during deployment. An igniter (squib) in each generator provides an ignition source when triggered by a fire signal from the airbag ECU. A 2 pin connector provides the interface between the igniter and the vehicle wiring.
On the driver’s airbag module, the housing is closed by a cover that forms the steering wheel centre pad; split lines are formed in the inner surface of the cover to direct the airbag through the required exit point during deployment. On the passenger’s airbag module, the housing is closed by a trim panel profiled to match the fascia; a tethered deployment door forms an integral part of the trim panel.
10
DESCRIPTION AND OPERATION
Page 94
Both airbag modules operate in the same way. On receipt of a fire signal from the airbag ECU, the igniter ignites the material in the gas generator. The burning material rapidly produces a large amount of nitrogen gas which passes through the filter screen into the airbag, forcing the airbag to unfold. On the driver airbag module, the unfolding airbag ruptures the cover along the split lines; on the passenger airbag module, the unfolding airbag breaks the deployment door fixings to the module housing and trim panel, and the deployment door lifts off the fascia (but remains tethered to the module housing). Once free of the housing the airbag inflates to its full extent. Vents in the airbag prevent excess pressure bursting the bag and, as soon as the material in the gas generator is exhausted, allows the airbag to instantly deflate.

Seat belt pretensioners
During a frontal collision the seat belt pretensioners tighten the front seat belts to ensure the occupants are securely held in their seats. A pretensioner is integrated into the buckle assembly of each front seat belt.
The two pretensioners are handed, but otherwise identical. Each pretensioner has a tube containing propellant and a piston. The piston is attached to a steel cable, the opposite end of which is attached to the seat belt buckle. An igniter (squib) in the base of tube provides an ignition source when triggered by a fire signal from the airbag ECU. A fly lead with a 2 pin connector links the igniter to the vehicle wiring.
On receipt of a fire signal from the airbag ECU, the igniter ignites the propellant. The burning propellant rapidly produces nitrogen gas that drives the piston along the tube, pulling on the cable and drawing the buckle towards the buckle assembly fixing point on the seat.
SRS warning lamp
The SRS warning lamp provides system status information for the driver. The lamp consists of a bulb behind a red SRS graphic at the base of the tachometer in the instrument pack. The bulb is a serviceable item that can be renewed from the rear of the instrument pack.

Rotary coupler
The rotary coupler is installed on the steering column to provide the interface between the fixed wiring harness and the moveable driver airbag module and horn buttons on the steering wheel.
A rotating link harness is encapsulated into a plastic cassette comprising outer and inner housings with integral connectors. Screws attach the outer housing to the steering column switch assembly and the inner housing is keyed to the steering wheel by its connector. The inner housing can turn a maximum of six revolutions in relation to the outer housing. For maintenance purposes the outer housing incorporates a position indicator wheel; a white tab is visible on the wheel when the rotary coupler is centralised. To prevent breaking the rotating link harness, both the steering and the rotary coupler must be centralised when removing and installing the steering wheel.
