PRECAUTIONS

PRECAUTIONS PFP:00001

Description EAS0019D

Observe the following precautions to ensure safe and proper servicing. Thes e precautions are not
described in each individual section.

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

The Supplemental Rest raint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, us ed along
with a front seat belt, helps to redu ce th e risk or se verit y of i njury to the driv er and front passenge r for ce rtain
types of collision. This sys tem includes seat belt switch inputs and dual s tage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man­ual.

WARNING:

● To avoid rendering the SRS inopera tive, which c ould increa se the risk of perso nal injury or dea th

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

● Improper maintenance, inc luding incorrect removal and installation of the SRS, can lead to per-

sonal injury ca use d by unintentional ac tiv atio n o f the system. For remo va l of Spiral Cable and Air
Bag Module, see the SRS section.

● Do not use electrical test equ ipment o n any circu it related to the SRS unless in structed to in this

Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

Precautions for NVIS/IVIS (NISSAN/INFINITI VEHICLE IMMOBILIZER SYSTEM ­NATS) (If Equipped)

NVIS/IVIS (N ATS) will immob il iz e th e e ng ine if s ome on e tri es t o s t ar t it wit h ou t t he r e gi ste re d ke y o f NVI S /IV I S
(NATS).
Both of the originally supplied ignition key IDs have been NVIS/IVIS (NATS) registered.
The security indic ator i s lo cated on the in strum ent panel. T he in di cato r blin ks wh en th e im mobi lizer sys tem i s
functioning.
Therefore, NVIS/IVIS (NATS) warns outsi ders that the ve hicle is equipped with the anti -theft system .

● When NVIS/IVIS (NATS) detects trouble, the security i ndicator lamp lights up while ignition switch is in

"ON" position.
This lighting up indicates that the anti-theft is not functioning, so prompt service is required.

● When servicin g NVIS/IVIS (NATS) (trouble diag noses, syst em initializatio n and addition al registration of

other NVIS/IVIS (NATS) ignition key IDs), CONSULT-II hardware and CONSULT-II NVIS/IVIS (NATS)
software is necessary.
Regarding the procedures of NVI S/IVIS (NATS) initialization and NVIS/I VIS (NATS) ignition key ID re gis­tration, refer to CONSULT-II operation manual, NVIS/IVIS (NATS).

Therefore, CONSULT-II NVIS/IVIS (NAT S) software (pro gram card an d operatio n manual) m ust be kept
strictly confidential to maintain the integrity of the anti-theft function.

● When servicin g NVIS/IVIS (NATS) (trouble diag noses, syst em initializatio n and addition al registration of

other NVIS/IVIS (NATS) ignition key IDs), it may be necessary to re-register original key identification.
Therefore, be sure to receive all keys from vehicle owner. A maximum of four or five key IDs can be regis­tered into NVIS/IVIS (NATS).

● When failing to start the engine first time using the key of NVIS/IVIS (NATS), start as follows.

1. Leave the ignition key in "ON" position for approximately 5 seconds.

2. Turn ignition key to "OFF" or "LOCK" position and wait approximately 5 seconds.

3. Repeat step 1 and 2 again.

4. Restart the engine while keeping the key separate from any others on key-chain.

PRECAUTIONS

General Precautions EAS0019G

● Do not ope rate t he en gine f or an exte nded perio d of t ime wi thou t

proper exhaust ventilation.
Keep the work area well ventilated and free of any inflammable
materials. Special care should be taken when handling any
inflammable or pois onous materials, suc h as gasoline, refrig er­ant gas, etc. When working in a pit or other enclosed area, be
sure to properly ventila te the area before working with haza rd­ous materials.
Do not smoke while working on the vehicle.

SGI285

● Before jacking up the vehicle, apply wheel chocks or other tire

blocks to the wheel s to prevent the vehicle from movin g. After
jacking up the vehicle, support the vehicle weight with safety
stands at the points designat ed for proper lifting be fore working
on the vehicle.
These operations should be done on a level surface.

● When removing a heavy component such as the en gin e or tra n-

saxle/transmiss io n, be care fu l not to los e yo ur ba la nc e an d dro p
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.

SGI231

● Before starting repairs which do not require battery power:

Turn off ignition switch.
Disconnect the negative battery terminal.

● If the battery termin als are disconnected, recorded memory of

radio and eac h control unit i s erased.

SEF289H

● To prevent serious burns:

Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.

● Dispose of drained oil or the solvent us ed for cleaning parts in

an appropriate manner.

● Do not attempt to top off the fuel tank aft er th e f ue l pu m p n ozzl e

shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel
spray and poss ibly a fire.

● Clean all disassembled parts in the designated liquid or solvent

prior to inspection or assembly.

● Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new

SGI233

ones.

● Replace inner and outer races of tapered roller bearings and needle bearings as a set.

● Arrange the disassembled parts in accordance with their assembled locations and sequence.

● Do not touch the terminals of electrical components which use microcomputers (such as ECM).

Static electricity may damage internal electronic components.

● After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.

● Use only the fluids and lubricants specified in this manual .

● Before servici ng the vehicle:

Protect fenders, u pholstery and carp eting with appropriat e cov­ers.
Take caution that keys, buckles or buttons do not scratch paint.

SGI234

WARNING:

To prevent ECM from storing the diagnostic trouble codes, do not carelessly d isconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.

Precautions for Three Way Catalyst EAS0019H

If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the ins tru cti on s.

● Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst .

● When checki ng for ignition spark or m easuring engine com pression, make tests q uickly and only whe n

necessary.

● Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to

the catalyst.

Do not place the vehicle on flammable ma terial. Keep flamm able material off the exha ust pipe and the thre e
way catalyst.

Use unleaded pr emi um ga soline with an oct a ne rat ing of at l east 91 AKI ( Anti -Kno ck Ind ex) nu mber (Resea rch
octane number 96).

If unleaded premium gasoline is not available, unleaded regular gasoline with an octane rating of at least 87
AKI number (Research octane number 91) can be used, bu t only under th e following precautions:

● have the fuel tank filled only partially with unleaded regular gasoline, and fill up with unleaded premium

gasoline as soon as possible.

● avoid full throttle drivin g and abrupt acceleration.

However, for maximum vehicle performanc e, the use of unleaded prem ium gasoline is recommended.

CAUTION:

Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel
other than that specified cou ld adversel y affect the emis sion control de vices and systems, and could
also affect the warranty coverage validi ty.

Precautions for Hoses EAS0019K

HOSE REMOVAL AND INSTALLATION

● To prevent damage to rubber hose, do not pry off rubber hose

with tapered tool or screwdriver.

● To reinstall the rubber ho se securely, make sure that hose inser-

tion length and orientation is correct. (If tube is equipped with
hose stopper, insert rubber hose into tube until it butts up
against hose stopper.)

HOSE CLAMPING

● If old rubber hose is re-used, install hose clamp in its original

position (at the ind entation whe re the ol d clamp wa s). If ther e is
a trace of tube bulging left on the old rubber hose, align rubber
hose at that position.

● Discard old clamps; replace with new ones.

Precautions for Engine Oils EAS0019L

Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact
with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.

HEALTH PROT EC TION 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.

● Heavily soil ed c l o thi ng a nd oil-impregnate d foo tw e ar s h ou ld not be worn. Ove r al ls m us t b e cleaned regu-

larly.

● First aid treatment should be obtained immediately for open cuts and wounds.

● Use barrier creams, applying them before each work period, to help the removal of oil from the skin.

● Wash with soap and water to ensu re all oil is removed (ski n clea nse rs a nd nail b rus hes will he lp) . Prepa-

rations containing la nolin replace the natural skin oils which have been re moved.

● Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.

● If skin disorders develop, obtain medical advice without delay.

● Where practical, degrease components prior to handling.

● Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles or face

shields; in addition an eye wash facility should be provided.

ENVIRONMENTAL PROTECTION PRECAUTIONS

Dispose of used oil and used oil filters through authorized waste disposal contractors to licensed waste dis­posal sites, or to the waste oil reclamation trade. If in doubt, contact the local authority for advice on disposal
facilities.
It is illegal to pour used oil on to the ground, down sewers or drains, or into water sources.

HOW TO PROBE CONNECTORS

Connector damage and an intermittent connection can result from improperly probing of the connector during
circuit checks.
The probe of a digital multimeter (DMM) may not correctly fit the connector cavity. To correctly probe the con­nector, follow the procedures belo w using a “T” pin. For the b est contact grasp the “T” pin using an alligat or
clip.

Probing from Harness Side

Standard type (not waterproof type) connector should be probed
from harness side with “T” pin.

● If the connector has a rear cover such as a ECM connector,

remove the rear cover before probing the terminal.

● Do not probe waterproof connector from harness side. Damage

to the seal between wire and co nnector may result.

SGI841

Probing from Terminal Side

FEMALE TERMINAL

● There is a small notch abov e each fe male te rminal. Pro be each

terminal with the “T” pin through the notch.
Do not insert any ob ject other th an the same type male termin al
into female terminal.

How to Check Enlarged Contact Spring of Terminal

An enlarged contact spring of a terminal may create intermittent signals in the circuit.
If the intermittent open circuit occurs, follow the procedure below to inspect for open wires and enlarged con­tact spring of female terminal.

1. Assemble a male terminal and approx. 10 cm (3.9 in) of wire.

Use a male terminal which matches the female terminal.

2. Disconnect the suspected faulty connector and hold it terminal
side up.

Waterproof Connector Inspection

If water enters the connector, it can short interior circuits. This may lead to intermittent problems.
Check the following items to maintain the original waterproof characteristics.

RUBBER SEAL INSPECTION

● Most waterproof connectors are provided with a rubber seal

between the male and female connectors. If the seal is missing,
the waterpro of performanc e may not meet spec ifications .

● The rubber seal may come off when connectors are discon-

nected. Whenev er connectors are reco nnected, make sure the
rubber seal is properly installed on either side of male or female
connector.

Determine which con necto rs an d wirin g ha rness woul d affect t he elec trical s yste m yo u are insp ecti ng. G entl y
shake each connect or and harness while monit oring the system for the inciden t you are trying to duplicate.
This test may indicate a loose or poor electrical connection.

HINT

Connectors can be exposed to moi sture. It is possibl e to get a thin film of corrosion on the co nnector termi­nals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs inter­mittently, perhaps the problem is ca used by corrosi on. It is a good i dea to disco nnect, inspec t and clean the
terminals on related connectors in the system.

SENSORS & RELAYS
Gently apply a slight vibration to sensors and relays in the system you are inspecting.

This test may indicate a loose or poorly mounted sensor or relay.

ENGINE COMPARTMENT

There are several reasons a vehicle or engine vibration could cause an electrical complaint. Some of the
things to check for are:

● Connectors not full y se ate d.

● Wiring harness not long enough and is being stressed due to engine vibrations or rocking.

● Wires laying across brackets or moving components.

● Loose, dirty or corroded ground wires.

● Wires routed too clos e to ho t components.

To inspect componen t s u nd er th e ho od, start by ve rif yi ng t h e i nte gr it y o f gro un d conne ct i on s. ( Re fer t o Gr ou nd
Inspection described later.) First check that the system is properly grounded. Then check for loose connection
by gently shak ing the wiring or comp onents as previously explained. Using th e wiring diagrams inspe ct the
wiring for continuity.

BEHIND THE INSTRUMENT PANEL

An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehi­cle vibration can aggravate a harness which is routed along a bracket or near a screw.

UNDER SEATING AREAS

An unclamped or loose harness can cause wiring to be pinched by seat components (such as slide guides)
during vehicle vibrat ion. If the wiring runs under seating are as, inspect wire routing for possible damage or
pinching.

Heat Sensitive

The customer's concern may occur during h ot weather or after car
has sat for a short time. In such cases you will want to check for a
heat sensitiv e condition.
To determine if an electrical component is heat sensitive, heat the
component with a heat gun or equivalent.
Do not heat compo nents above 60°C (140°F). If incident occurs
while heating th e unit, either repla ce o r p rop erly insulate the c om p o­nent.

SGI842

Freezing

The customer may indicate the incident goes away after the car
warms up (wint e r tim e) . T he c au se co ul d be r el a ted to wa te r fr ee zi ng
somewhere in the wiring/electrical system.
There are two me thods to check for this. The first is to arra nge for
the owner to leave his car overnight. Make sure it will get cold
enough to demonstrate his complaint. Leave the car parked outside
overnight. In the morning, do a quick and thorough diagnosis of
those electrical components which could be affected.
The second m ethod is to put the sus pect component int o a freezer
long enough for any water to freeze. Reinstall the part into the car
and check for the re occurrence of the inci dent. If it o ccurs, repair or
replace the compone nt .

SGI843

Water Intrusion

The incident may occur only during high humidity or in rainy/snowy
weather. In such cases the in cident could be c aused by wa ter intru­sion on an electrical part. This can be simulated by soaking the car
or running it through a car wash.

Do not spray water directly on any electrical components.

Electrical Load

The incident may be electrical load sensitive. Perform diagnosis with
all accessories (including A/C, rear window defogger, radio, fog
lamps) turned on.

CIRCUIT INSPECTION
Introduction

In general, testing electrical circuits is an easy task if it is approached in a logical and organized method.
Before beginning it is important to have all available information on the system to be tested. Also, get a thor­ough understanding of system opera tion. Then you will be able to use the approp riate equipm ent and follow
the correct test procedure.
Yo u may hav e to sim ulate vehi cle v ibr ation s whil e test ing e lectri cal c ompo nents. Ge ntly s hak e the wi ring h ar­ness or electrical component to do this.

OPEN A circ ui t is open when there is no continuity through a section of the circuit.

There are two types of shorts.

SHORT

● SHORT CIRCUIT

● SHORT TO GROUND When a circuit contacts a ground source and grounds the circuit.

When a circuit contacts another circuit and causes the norm al resistanc e to
change.

NOTE:

Refer to “How to Check Terminal” to probe or check terminal.

Testing for “Opens” in the Circuit

Before you begin to diagnose and test the system, you should rough sketch a schematic of the system. This
will help you to logically walk through the diagnosis process. Drawing the sketch will also reinforce your work­ing knowledge of the system.

SGI846-A

CONTINUITY CHECK METHOD

The continuity check is used to find an open in the circuit. The digital multimeter (DMM) set on the resistance
function will indicate an open circuit as over limit (no beep tone or no ohms symbol). Make sure to always start
with the DMM at the highest resistance level.
To help in understanding the diagnosis of open circuits, please refer to the previous schematic.

● Disconnect the ba tte ry ne gative cable.

● Start at one end of the circuit and work your way to the other end. (At the fuse block in this example)

● Connect one probe of the DMM to the fuse block terminal on the load side.

● Connect the ot her probe to the fuse b lock (power) side of SW1. Little or no resis tance will indicate th at

portion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an
over limit or infinite resistance condition. (point A)

● Connect the prob es be tw ee n SW 1 an d th e re la y. Little or no resistance wil l ind ic at e th at p ort ion of th e c ir-

cuit has good conti nuity. If there were an open in the circuit, the DMM would in dicate an over limi t or infi­nite resist ance condition. (point B)

● Connect the probes between the relay and the solenoid. Little or no resistance will indicate that portion of

the circuit ha s g oo d co nt inu it y. If there were an open in t he cir cu it , th e DM M w o uld i n di ca te an ov er l im it o r
infinite resi stance condition. (point C)

Any circuit can be diagnosed using the approach in the previous example.

VOLTAGE CHECK METHOD

To help in understanding the diagnosis of open circ uits please refer to the previous schematic.
In any powered circu it, an open can b e fou nd by method ical ly ch ecki ng the syste m for t he p res ence of volt a ge.
This is done by switching the DMM to the voltage function.

● Connect o ne probe of the DMM to a known good gr ound.

● Begin probing at one end of the circuit and work your way to the other end.

● With SW1 open, probe at SW1 to check for voltage.

voltage; open is further down the ci rcuit than SW1.
no voltage; open is between fuse block and SW1 (point A).

● Close SW1 and probe at relay.

voltage; open is further down the circuit than the relay.
no voltage; open is between SW1 and relay (point B).

● Close the relay and probe at the solenoid.

Testing for “Shorts” in the Circuit

To simplify the discussion of shorts in the system, please refer to the following schematic.

SGI847-A

RESISTANCE CHECK METHOD

● Disconnect the battery negative cable and remove the blown fuse.

● Disconnect all loads (SW1 open, relay disconnected and solenoid disconnected) powered through the

fuse.

● Connect one probe of the DMM to the load side of the fuse terminal. Connect the other probe to a known

good ground.

● With SW1 open, check for continuity.

continuity; short is between fuse terminal and SW1 (point A).
no continuity; short is further down the circuit than SW1.

● Close SW1 and disconn ect the relay. Put probes at the lo ad side of fuse terminal and a known good

Ground Inspection

Ground connections are very important to the proper operation of electrical and electronic circuits. Ground
connections are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can
become an unwant ed resistance. This unwant ed resistance can change the way a circuit works.
Electronical ly cont rol l ed ci rcui t s a r e ve ry se ns it ive to prop er gr ou ndin g. A lo ose or co r rod ed gro un d ca n d rast i­cally affect an elec tronically controlled circui t. A poor or corroded ground c an easily affect the circuit. Eve n
when the groun d connection lo oks clean, there can be a thin fil m of rust on the su rface.
When inspecting a ground connection follow these rules:

● Remove the ground bolt or screw.

● Inspect all mating surfaces for tarnish, dirt, rust, etc.

● Clean as required to assure good contact.

● Reinstall bolt or screw securely.

● Inspect for “add-on” acce ssories which may be interfering with the ground circuit.

● If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the

wires are clean, securely fastened and providing a good ground path. If multiple wires are cased in one
eyelet make sure no ground wires have excess wire insulation.

For detailed ground distribution information, refer to “Ground Distribution” in PG section.

Vo ltage Drop Tests

Voltage drop tests are often used to find co mponents or circuits whic h have excessiv e resistance. A voltage
drop in a circuit is caused by a resistance when the circuit is in operation.
Check the wire in the illustration. When measuring resistance with DMM, contact by a single strand of wire will
give reading of 0 ohms. This would indicate a good circuit. When the circuit operates, this single strand of wire
is not able to carry the current. The single strand will have a high resistance to the current. This will be picked
up as a slight voltage drop.
Unwanted resistance can be caused by many situations as follows:

● Undersized wiring (single strand example)

● Corrosion on switch contacts

● Loose wire connec tions or splices.

Revision: 2005 March 2005 Q45

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

If repairs are needed always use wire that is of the same or larger gauge.

MEASURING VOLTAGE DROP — ACCUMULATED METHOD

● Connect the DMM ac ross the co nnector or part of the circ uit you wa nt to check. The posit ive lead of t he

DMM should be closer to power and the negative lead closer to ground.

● Operate the circuit.

● The DMM will indicate how many volts are being used to “p ush” current through that part of the circuit.

Note in the illustration that there is an excessive 4.1 volt drop between the battery and the bulb.

SGI974

MEASURING VOLTAGE DROP — STEP-BY-STEP

The step-by-step method is most useful for isolating excessive drops in low voltage systems (such as those in
“Computer Controlled Systems”).
Circuits in the “Computer Controlled System” operate on very low amperage.
The (Computer Controlled) system operations can be adversely affected by any variation in resistance in the
system. Such resistance variation may be caused by poor connection, improper installation, improper wire
gauge or corros ion.
The step by step v oltage drop test can identify a component or wire with too much resistance.

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front sea t belt , helps t o redu ce th e r isk or s everi ty of injury to th e driv er an d front passenge r for c ertain
types of collisi on . Thi s s ys te m in cludes seat belt swi tch inp uts an d du al stage front air bag modules . The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information ne ce ss ary t o se rvi ce th e sy stem saf e ly is i nclu de d in th e SR S and SB se ct i on of th is Ser vic e Man­ual.

WARNING:

● To avoid rendering the SRS inoperative, wh ich could increa se the risk of personal injury or de ath

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

● Improper maintenance, incl uding incorrect removal and installation of the SRS, can lead to pe r-

sonal injury caused by unintentional activation of the system. For rem ova l of Sp iral Ca ble an d Air
Bag Module, see the SRS section.

● Do not use electrical test equipment on any circ uit related to the SRS unless instructed to in this

Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors .

DESCRIPTION PFP:00000
Outline EKS00GFA

The Intelligent Cruise Control (ICC) system automatically maintains a selected distance from the vehicle
ahead accordi ng to that vehicle's speed, or at the set speed, if the road ahead is clear.
The ICC function has two cruise control mode s and brake assi st (with preview function).

VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE

Vehicle-to-vehicle distance control mode, the driver can maintain the same speed as other vehicles without
the constant need to adjust the set speed as you would with a normal cruise control system.
The system is in tended to enhance the op eration of the vehicle when f ollowing the vehicle trave ling in the
same lane and direction.

The system automatically controls the throttle and applies the brakes (up to 25% of vehicle braking power) if
necessary.
The detection range of the sensor is approximately 390 ft (120 m) ahead.
Refer to Owner's Manual for Intelligent Cruise Control System operating instructions.

CONVENTIONAL (FIXED SPEED) CRUISE CONTROL MODE

Conventional (fixed speed) cr uise control mode is cruising at preset speeds.
Refer to Owner's Manual for Intelligent Cruise Control System operating instructions.

BRAKE ASSIST (WITH PREVIEW FUNCTION)

When the force applie d to brake p edal exc eeds a certain lev el, the Brak e Assist is activated and gene rates a
greater braking force than that of a conventional brake booster even with light pedal force.
When the Preview Fun ct ion identifies the nee d to app ly the sudden brake by se ns in g th e ve hicle ahead in the
same lane and the distance and relative speed from it, it applies the brake pre-pressure before driver depress
the brake peda l and improves b rake response by reducing its free play.

CAN Communication EKS003OR

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul­tiplex communication line with high data communication speed and excellent error detection ability. Many elec­tric control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during opera tion (not independent). In CA N communication, cont rol units are connected with 2
communicatio n lines ( CAN H lin e, CAN L li ne) all owi ng a high ra te of in forma tion tr ans missi on wit h less wir ing.
Each control unit transmits/receives data but selectively reads required dat a only.
