PRECAUTIONS

PRECAUTIONS PFP:00001

Description NAS00073

Observe the following precautions to ensure safe and proper servicing. These 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 system includes seat belt switch inputs and dual s tage front ai r 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 activ ation of the system. For removal of Spiral Cable and A ir 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.

NAS00074

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 outsiders 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 approximat ely 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

Precautions Necessary for Steering Wheel Rotation After Battery Disconnect

NAS0008J

NOTE:

● This Procedure is appl ied only to models with Intel ligent Key system and NVI S/IVIS (NISSAN/INFINITI

VEHICLE IMMOBILIZER SYSTEM - NATS).

● Remove and install all control units after disconnect ing both battery cables with the ignition knob in the

″LOCK″ position.

● Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing

work. If DTC is detected, perform trouble diagnosis according to self- diagnostic results.

For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lock mechanism is adopted on the key cylinder. For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and steering whee l rotation will become impossible. If steering wh eel rotation is required when battery power is interrupted, follow th e procedure below before starting the repair operation.

OPERATION PROCEDURE

1. Connect both battery cables.

NOTE:

Supply power using jumper cables if battery is discharged .

2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the steering lock will be released.

3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be rotated.

4. Perform the necessary repair operation.

5. When the repair work is completed, return t he ignition switch to the ″LOCK″ positi on before connec ting the battery cables. (At this time, the steering lock mechanism will engage.)

6. Perform a self-diagnosis check of all control units using CONSULT-II.

Precautions for Procedures with out Cowl Top Cover NAS00077

When performi ng the pr oced ure af ter remo ving cowl t op cove r, cover the lower end of windshield with uretha ne, etc.

PIIB3706J

General Precautions NAS00078

● 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 flammable materials. S pecia l car e sh ould be t ake n when hand lin g any flammable or poisonous materials, such as gasoline, refrigerant gas, etc. When working in a pit or other enclosed area, be sure to properly ventilate the area before working with hazardous materials.

● Dispose of or recy cle dr a in ed oi l or th e solv en t us ed fo r cle an in g

parts in an appropriat e manner.

● Do not attempt to top off the fuel tank after the fuel pu mp no zz le

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

● Clean all disassembled parts in the designated liquid or solvent

prior to inspection or assemb ly.

● 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 elec tronic components.

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

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

● Use approved bonding agent, sealants or their equivalents when required.

● Use hand tools, power tools (disassembly only) and recom-

mended special tools where specified for safe and efficient service repairs.

● When repairing the fu el, oil, wate r, vacuum or exhaust sys tems,

check all affected lines for leaks.

PRECAUTIONS

● Before servicing the vehicle:

Protect fenders, uph olstery and carpet ing with appropria te covers. Take caution that keys, buckles or buttons do not scratch paint.

SGI234

WARNING:

To prevent ECM from storing the diagnostic tro uble codes, d o not carelessly disconnect th e 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 NAS00079

If a large amount of un bu rne d fu el flows into the catalys t, th e c ataly st te m pe r atu re wi ll b e ex c es si ve ly high. To prevent this, follow the instructions.

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

● When checking for i gnition spark or measuri ng engine compressio n, make tests quickly a nd only when

necessary.

● Do not run engine when the fuel tank level is lo w, otherwise the engine may m isfire, causin g damage to

the catalyst.

Do not place the vehi cle on flammab le material. Keep flam mable material off the exhaust pipe and the three way catalyst.

Precautions for Fuel (Unleaded Premium Gasoline Recommended) NAS0007A

Use unleaded reg ular gaso line with an oc tane rati ng of at le ast 8 7 AKI (Anti-Kn ock Index ) num ber (Re searc h octane numb er 91).

For improved ve hicle performance, NISSAN/INFINITI recommend the use o f unleaded premium gasoline with an octane rating of at least 91 AKI number (Research octane number 96).

CAUTION:

Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Do not use E-85 fuel (85% fuel ethanol, 15% unleaded gasoline) unless the vehicle is specifically designed for E-85 fuel (i.e. Flexible Fuel Vehicle - FFV models). Using a fuel othe r than that specified could ad versely affect the emission control devices and systems, and could also affect the warranty coverage validity.

Precautions for Fuel (Unleaded Premium Gasoline Required) NAS0007B

Use unleaded premiu m gas olin e wit h an o ct ane ratin g of at le ast 91 A KI ( Anti- Knoc k Ind ex) numbe r (Res ear ch octane numb er 96).

If unleaded premium gasoline is not avai lable, unleade d regular gasoli ne with an octane rating of at least 87 AKI number (Research oct ane number 91) can be used, but only under the following p recautions:

● have the fuel tank filled on ly partially with unleaded re gular gasoline, and fil l up with unleaded prem ium

gasoline as soon as possible.

● avoid full throttle driving and abrupt acceleration.

However, for maximum vehicle performance, the use of unleade d premi um ga sol ine is recom mende d.

CAUTION:

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 connector 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.

4. While moving the connector, check whether the male terminal can be easily inserted or not.

● If the male terminal can be easily inserted into the female termi-

nal, replace the female terminal.

SEL272V

SEL273V

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 specifications.

● 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.

INCIDENT SIMULATION TESTS Introduction

Sometimes the symptom is not present when the vehicle is brought in for service. If possible, re-create the conditions present at the time of the incident. Doing so may help avoid a No Trouble Found Diagnosis. The following section illustrates ways to simulate the conditions/environment under which the owner experiences an electrical incident. The section is broken into the six following topics:

● V ehicle vibration

● Heat sensitive

Revision: 2006 January 2006 M35/M45

GI-28

Page 35

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

● Freezing

● Water intrusion

● Electrical load

● Cold or hot start up

Get a thorough description of the incident from the customer. It is important for simulating the conditions of the problem.

Vehicle Vibration

The problem may occu r or be com e wors e wh ile dr iving on a roug h road or whe n eng ine i s vibrat in g (idl e with A/C on). In such a case , you w ill wan t to ch eck f or a vib rati on rel ated con ditio n. Re fer to th e foll owing i llu stration.

CONNECTORS & HARNESS

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.

SGI839

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 enou gh and is being st ressed 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 con ne ct i ons. ( 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.

Revision: 2006 January 2006 M35/M45

GI-29

Page 36

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

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 erl y ins u late the component.

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.

SGI844

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

Cold or Hot Start Up

On some occas ions an elec trical incide nt may occur on ly when the ca r is started col d, or it may oc cur when the car is restarted hot shortly after being turned off. In these cases you may have to keep the car overnight to make a proper diagno sis.

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.

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 unwanted 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 film of rust on the surface. 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” accessories 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.

SGI853

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 splic es.

Revision: 2006 January 2006 M35/M45

GI-33

Page 40

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 “push” current through that p art 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 identi fy a component or wire with too much resistance.

DESCRIPTION

[ICC]

DESCRIPTION PFP:00000 Outline NKS004CF

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 modes and brake assist (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 adjus t the set speed as the driver 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. If the ICC sens or in te gra ted un it detects a slower m oving vehicle ahea d, t he sy st em will reduce speed so that the vehicle ahead can be followed at the select ed distance. 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 sud de n b r ak e by se ns in g th e vehicle ahead in the same lane and the distance and relative speed from it, it applies the brake pre-pressure before driver depresses the brake pedal and improves brake response by reducing its free play. Refer to Owner's Manual for BRAKE ASSIST (WITH PREVIEW FUNCTION) operating instructions.

CAN Communication NKS004CI

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 transmit s/receives data but selectively reads required data on ly.
