PRECAUTIONS

Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER” used along with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. The SRS system composition which is available to INFINITI I30 is as follows:

! For a frontal collision

The Supplemental Restraint System consists of driver air bag module (located in the center of the steering wheel), front passenger air bag module (located on the instrument panel on passenger side), seat belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.

! For a side collision

The Supplemental Restraint System consists of front side air bag module (located in the outer side of front seat), satellite sensor, diagnosis sensor unit (one of components of air bags for a frontal collision), wiring harness, warning lamp (one of components of air bags for a frontal collision).

Information necessary to service the system safely is included in the RS section of this Service Manual.

WARNING:

! To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death

in the event of a collision which would result in air bag inflation, all maintenance should be performed by an authorized INFINITI dealer.

! Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-

sonal injury caused by intentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the RS section.

! Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this

Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just before the harness connectors or for the complete harness are related to the SRS.

NHST0001

Precautions for Steering System

! Before disassembly, thoroughly clean the outside of the unit. ! Disassembly should be done in a clean work area. It is important to prevent the internal parts from

becoming contaminated by dirt or other foreign matter.

! Place disassembled parts in order, on a parts rack, for easier and proper assembly. ! Use nylon cloths or paper towels to clean the parts; common shop rags can leave lint that might

interfere with their operation.

! Before inspection or reassembly, carefully clean all parts with a general purpose, non-flammable

solvent.

! Before assembly, apply a coat of recommended power steering fluid* to hydraulic parts. Vaseline

may be applied to O-rings and seals. Do not use any grease.

! Replace all gaskets, seals and O-rings. Avoid damaging O-rings, seals and gaskets during instal-

lation. Perform functional tests whenever designated. *: Genuine Nissan PSF II or equivalent. Refer to MA-11, “Fluids and Lubricants”.

Checking Steering Wheel Turning Force

NHST0015

1. Park vehicle on a level, dry surface and set parking brake.

2. Start engine.

3. Bring power steering fluid up to adequate operating temperature. [Make sure temperature of fluid is approximately 60 to 80°C (140 to 176°F).]

Tires need to be inflated to normal pressure.

4. Check steering wheel turning force when steering wheel has been turned 360° from the neutral position.

Steering wheel turning force:

39 N (4 kg, 9 lb) or less

5. If steering wheel turning force is out of specification, check rack sliding force.

a. Disconnect steering column lower joint and knuckle arms from

the gear.

b. Start and run engine at idle to make sure steering fluid has

reached normal operating temperature.

c. Pull tie-rod slowly to move it from neutral position to ±11.5 mm

(±0.453 in) at speed of 3.5 mm (0.138 in)/s. Check that rack sliding force is within specification.

Average rack sliding force:

216 - 284 N (22 - 29 kg, 49 - 64 lb)

Maximum force deviation:

98 N (10 kg, 22 lb)

d. Check sliding force outside the above range at rack speed of

40 mm (1.75 in)/s.

Rack sliding force:

Not more than 294 N (30 kg, 66 lb)

Maximum force deviation:

147 N (15 kg, 33 lb)

6. If rack sliding force is not within specification, overhaul steering gear assembly.

7. If rack sliding force is OK, inspect steering column. Refer to ST-13.

Checking Hydraulic System

SST834-F

Checking Hydraulic System

Before starting, check belt tension, driving pulley and tire pressure.

1. Set Tool. Open shut-off valve. Then bleed air. Refer to “Bleeding Hydraulic System”, ST-7.

2. Run engine at idle speed or 1,000 rpm.

Make sure temperature of fluid in tank rises to 60 to 80°C (140 to 176°F).

WARNING:

Warm up engine with shut-off valve fully opened. If engine is started with shut-off valve closed, fluid pressure in oil pump increases to maximum. This will raise oil temperature abnormally.

3. Check pressure with steering wheel fully turned to left and right positions with engine idling at 1,000 rpm.

CAUTION:

Do not hold the steering wheel in a locked position for more than 15 seconds.

Oil pump maximum standard pressure:

8,140 - 8,728 kPa (83 - 89 kg/cm

! If pressure reaches maximum operating pressure, system is

OK.

! If pressure increases above maximum operating pressure,

check power steering pump flow control valve. Refer to ST-25.

4. If power steering pressure is below the maximum operating pressure, slowly close shut-off valve and check pressure again.

CAUTION:

Do not close shut-off valve for more than 15 seconds.

! If pressure increases to maximum operating pressure, gear is

damaged. Refer to “Removal and Installation”, ST-16.

! If pressure remains below maximum operating pressure, pump

is damaged. Refer to “Disassembly”, ST-26.

5. After checking hydraulic system, remove Tool and add fluid as necessary. Then completely bleed air out of system. Refer to ST-7.

! For a frontal collision

! For a side collision

Information necessary to service the system safely is included in the RS section of this Service Manual.

WARNING:

! To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death

in the event of a collision which would result in air bag inflation, all maintenance should be performed by an authorized INFINITI dealer.

! Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-

sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the RS section.

! Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this

Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just before the harness connectors or for the complete harness are related to the SRS.

How to Handle Battery

CAUTION:

! If it becomes necessary to start the engine with a booster

battery and jumper cables, use a 12-volt booster battery.

! After connecting battery cables, ensure that they are

tightly clamped to battery terminals for good contact.

! Never add distilled water through the hole used to check

specific gravity.

METHODS OF PREVENTING OVER-DISCHARGE

The following precautions must be taken to prevent over-discharging a battery.

! The battery surface (particularly its top) should always be kept

clean and dry.

! The terminal connections should be clean and tight. ! At every routine maintenance, check the electrolyte level.

This also applies to batteries designated as “low maintenance” and “maintenance-free”.

! When the vehicle is not going to be used over a long period of

time, disconnect the negative battery terminal. (If the vehicle has an extended storage switch, turn it off.)

NHSC0003

NHSC0003S01

MEL041F

MEL042F

! Check the charge condition of the battery.

Periodically check the specific gravity of the electrolyte. Keep a close check on charge condition to prevent over-discharge.

CHECKING ELECTROLYTE LEVEL

WARNING:

Do not allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touching a battery, do not touch or rub your eyes until you have thoroughly washed your hands. If acid contacts eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention.

BATTERY

! Remove the cell plug using a suitable tool. ! Add distilled water up to the MAX level.

Sulphation

A battery will be completely discharged if it is left unattended for a long time and the specific gravity will become less than

1.100. This may result in sulphation on the cell plates.

To determine if a battery has been “sulphated”, note its voltage and current when charging it. As shown in the figure, less current and higher voltage are observed in the initial stage of charging sulphated batteries. A sulphated battery may sometimes be brought back into service by means of a long, slow charge, 12 hours or more, followed by a battery capacity test.

SPECIFIC GRAVITY CHECK

1. Read hydrometer and thermometer indications at eye level.

System Description

CHARGING SYSTEM

System Description

The alternator provides DC voltage to operate the vehicle’s electrical system and to keep the battery charged. The voltage output is controlled by the IC regulator. Power is supplied at all times to alternator terminal 3 (S) through:

! 120A fusible link (letter a, located in the fuse and fusible link box), and ! 10A fuse (No. 70, located in the fuse and fusible link box).

Terminal B supplies power to charge the battery and operate the vehicle’s electrical system. Output voltage is controlled by the IC regulator at terminal 3 (S) detecting the input voltage. The charging circuit is protected by the 120A fusible link. The alternator is grounded to the engine block. With the ignition switch in the ON or START position, power is supplied

! through 10A fuse [No. 30, located in the fuse block (J/B)] ! to combination meter terminal 66 for the charge warning lamp.

Ground is supplied to terminal 68 of the combination meter through terminal 2 (L) of the alternator. With power and ground supplied, the charge warning lamp will illuminate. When the alternator is providing sufficient voltage with the engine running, the ground is opened and the charge warning lamp will go off. If the charge warning lamp illuminates with the engine running, a fault is indicated.

Precautions

SUPPLEMENTAL RESTRAINT SYSTEM (SRS) “AIR BAG” AND “SEAT BELT PRE-TENSIONER”

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER” used along with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. The SRS composition which is available to INFINITI I30 is as follows:

! For a frontal collision

! For a side collision

WARNING:

! To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death

in the event of a collision which would result in air bag inflation, all maintenance should be performed by an authorized INFINITI dealer.

! Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-

sonal injury caused by unintentional activation of the system.

! Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this

Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just before the harness connectors or for the complete harness are related to the SRS.

PRECAUTION FOR SEAT BELT SERVICE

CAUTION:

! Before removing the seat belt pre-tensioner assembly, turn the ignition switch off, disconnect both

battery cables and wait at least 3 minutes.

! Do not use electrical test equipment for seat belt pre-tensioner connector. ! After replacing or reinstalling seat belt pre-tensioner assembly, or reconnecting seat belt pre-ten-

sioner connector, check the system function. Refer to “SRS Operation Check” for details. (RS-41)

! Do not use disassemble buckle or seat belt assembly. ! Replace anchor bolts if they are deformed or worn out. ! Never oil tongue and buckle. ! If any component of seat belt assembly is questionable, do not repair. Replace the whole seat belt

assembly.

! If webbing is cut, frayed, or damaged, replace seat belt assembly. ! When replacing seat belt assembly, use a genuine seat belt assembly.

After A Collision

WARNING:

Inspect all seat belt assemblies including retractors and attaching hardware after any collision. NISSAN recommends that all seat belt assemblies in use during a collision be replaced unless the collision was minor and the belts show no damage and continue to operate properly. Failure to do so could result in serious personal injury in an accident. Seat belt assemblies not in use during a collision should also be replaced if either damage or improper operation is noted. Seat belt pre-tensioner should be replaced even if the seat belts are not in use during a frontal collision in which the air bags are deployed.

Replace any seat belt assembly if: ! The seat belt was in use at the time of a collision (except for minor collisions and the belts, retractors and

buckles show no damage and continue to operate properly).

! The seat belt was damaged in an accident. (i.e. torn webbing, bent retractor or guide, etc.) ! The seat belt attaching point was damaged in an accident. Inspect the seat belt attaching area for dam-

age or distortion and repair as necessary before installing a new seat belt assembly.

! Anchor bolts are deformed or worn out. ! The seat belt pre-tensioner should be replaced even if the seat belts are not in use during the collision in

! Anchor bolts are deformed or worn out. ! The seat belt pre-tensioner should be replaced even if the seat belts are not in use during the collision in

which the air bags are deployed.

PRELIMINARY CHECKS

1. Check the air bag warning lamp/chime for proper operation as follows:

a. Switch ignition ON. The air bag warning lamp should illuminate. Also, the air bag warning chime should

sound for about seven seconds.

b. Fasten driver’s seat belt. The seat belt warning lamp should go out and the chime (if sounding) should

stop.

c. If the air bag warning lamp is blinking, conduct self-diagnosis using CONSULT-II, and air bag warning lamp.

Refer to “SRS Operation Check”, RS-41.

2. Check that the seat belt retractor, seat belt anchor and buckle bolts are securely attached.

3. Check the shoulder seat belt guide and shoulder belt height adjuster for front seats. Ensure guide swivels freely and that belt lays flat and does not bind in guide. Ensure height adjuster operates properly and holds securely.

4. Check retractor operation:

a. Fully extend the seat belt webbing and check for twists, tears or other damage. b. Allow the seat belt to retract. Ensure that belt returns smoothly and completely into the retractor. If the seat

belt does not returns smoothly, wipe the inside of the loops with a clean paper cloth etc. because dirt built up in the loops of the upper anchors can cause the seat belts to retractor slowly.

c. Fasten the seat belt. Pull firmly on belt and buckle to ensure belt remains latched. Unfasten seat belt.

Ensure belt releases freely and buckle button returns to original position.

SEAT BELT RETRACTOR ON-VEHICLE CHECK Emergency Locking Retractors (ELR) and Automatic Locking Retractors (ALR)

NHRS0052S03

NHRS0052S0301

NOTE:

All seat belt retractors are of the Emergency Locking Retractors (ELR) type. In an emergency (sudden stop) the retractor will lock and prevent the belt from extending any further. All 3-point type seat belt retractors except the driver’s seat belt also have an Automatic Locking Retractors (ALR) mode. The ALR mode (also called child restraint mode) is used when installing child seats. The ALR mode is activated when the seat belt is fully extended. When the belt is then retracted partially, the ALR mode automatically locks the seat belt in a specific position so the belt cannot be extended any further. To cancel the ALR mode, allow the seat belt to fully wind back into the retractor.

Check the seat belt retractors using the following test(s) to determine if a retractor assembly is operating properly.

ELR Function Stationary Check

NHRS0052S0302

Grasp the shoulder belt and pull forward quickly. The retractor should lock and prevent the belt from extending further.

ALR Function Stationary Check

NHRS0052S0303

1. Pull out entire length of seat belt from retractor until a click is heard.

2. Retract the belt partially. A clicking noise should be heard as the belt retracts indicating that the retractor is in the Automatic Locking Retractors (ALR) mode.

3. Grasp the seat belt and try to pull out the retractor. The belt must lock and not extend any further. If NG, replace the retractor assembly.

4. Allow the entire length of the belt to retract to cancel the automatic locking mode.

ELR Function Moving Check

NHRS0052S0304

WARNING:

Perform the following test in a safe, open area clear of other vehicles and obstructions (for example, a large, empty parking lot). Road surface must be paved and dry. DO NOT perform the following test on wet or gravel roads or on public streets and highways. This could result in an accident and serious personal injury. The driver and passenger must be prepared to brace themselves in the event the retractor does not lock.

1. Fasten driver’s seat belt. Buckle a passenger into the seat for the belt that is to be tested.

2. Proceed to the designated safe area.

3. Drive the vehicle at approximately 16 km/h (10 MPH). Notify any passengers of a pending sudden stop and the driver and passenger must be prepared to brace themselves in the event the retractor does not lock, apply brakes firmly and make a very hard stop.

During stop, seat belts should lock and not be extended. If the seat belt retractor assembly does not lock, perform the retractor off-vehicle check.

SEAT BELT RETRACTOR OFF-VEHICLE CHECK

NHRS0052S04

1. Remove the seat belt retractor assembly.

2. Slowly pull out belt while tilting the retractor assembly forward from the mounted position without twisting the retractor assembly as shown in the illustration.

! Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual. ! Before servicing the SRS, turn ignition switch “OFF”, disconnect both battery cables and wait at least 3

minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.

! Diagnosis sensor unit must always be installed with their arrow marks “g” pointing towards the front of

the vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before installation and replace as required.

! The spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to

turn steering wheel or column after removal of steering gear.

! Handle air bag module carefully. Always place driver and passenger air bag modules with the pad side

facing upward and place side air bag module (built-in type) standing with stud bolt side setting bottom.

! Conduct self-diagnosis to check entire SRS for proper function after replacing any components. ! After air bag inflates, the front instrument panel assembly should be replaced if damaged.

SRS Configuration

SRS585-B

The air bag deploys if the diagnosis sensor unit activates while the ignition switch is in the “ON” or “START” position. The collision modes for which supplemental restraint systems are activated are different among the SRS systems. For example, the driver air bag module and passenger air bag module are activated in a frontal collision but not in a side collision. SRS configurations which are activated for some collision modes are as follows;

SRS configuration Frontal collision Left side collision Right side collision

Seat Belt Pre-tensioner with Load Limiter

SRS444

Seat Belt Pre-tensioner with Load Limiter

=NHRS0034

The seat belt pre-tensioner system with load limiter is installed to both the driver’s seat and the front passenger’s seat. It operates simultaneously with the SRS air bag system in the event of a frontal collision with an impact exceeding a specified level. When the frontal collision with an impact exceeding a specified level occurs, seat belt slack resulting from clothing or other factors is immediately taken up by the pre-tensioner. Vehicle passengers are securely restrained. When passengers in a vehicle are thrown forward in a collision and the restraining force of the seat belt exceeds a specified level, the load limiter permits the specified extension of the seat belt by the twisting of the ELR shaft, and a relaxation of the chest-area seat belt web tension while maintaining force.

Built-in Type Side Air Bag
