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

EIS000OI

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. 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 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 must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit 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.

Precautions for work

CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs.Use the Diagnostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customer's comments; refer BL-11, "Diagnostic Worksheet" . This information is necessary to duplicate the
conditions that exist when the noise occurs.
●
The customer may not be able to provide a detailed description or the location of the noise. Attempt to
obtain all the facts and conditions that exist when the noise occurs (or does not occur).
●
If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer
is concerned about. This can be accomplished by test driving the vehicle with the customer.
●
After identifying the type of noise, isolate the noise in terms of its characteristics.The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
●
Squeak —(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard surfaces=higher pitch noise/softer surfaces=lower pitch noises/edge to surface=chirping
●
Creak—(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch
dependent on materials/often brought on by activity.
●
Rattle—(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
●
Knock —(Like a knock on a door)
Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.
●
Tick—(Like a clock second hand)
Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver
action or road conditions.
●
Thump—(Heavy, muffled knock noise)
Thump characteristics include softer knock/dead sound often drought on by activity.
●
Buzz—(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.
●
Often the degree of acceptable noise level will vary depending upon the person. A noise that you may
judge as acceptable may be very irritating to the customer.
●
Weather conditions, especially humidity and temperature, may have a great effect on noise level.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
DUPLICATE THE NOISE AND TEST DRIVE
If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or location of the noise. This information can be used to
duplicate the same conditions when you confirm the repair.
If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to duplicate the noise with the vehicle stopped by doing one or all of the following:
1) Close a door.
2) Tap or push/pull around the area where the noise appears to be coming from.
3) Rev the engine.
4) Use a floor jack to recreate vehicle "twist".
5) At idle, apply engine load (electrical load, half-clutch on M/T model, drive position on A/T model).
6) Raise the vehicle on a hoist and hit a tire with a rubber hammer.
●
Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.
●
If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the
vehicle body.

CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, check ASIST for Technical Service Bulletins (TSBs) related
to that concern or symptom.
If a TSB relates to the symptom, follow the procedure to repair the noise.

LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE
1.
2.
●

●

●
●

G
Narrow down the noise to a general area.To help pinpoint the source of the noise, use a listening tool
(Chassis Ear: J-39570,Engine Ear: J-39565 and mechanics stethoscope).
Narrow down the noise to a more specific area and identify the cause of the noise by:
H
removing the components in the area that you suspect the noise is coming from.
Do not use too much force when removing clips and fasteners, otherwise clips and fastener can be broken
or lost during the repair, resulting in the creation of new noise.
BL
tapping or pushing/pulling the component that you suspect is causing the noise.
Do not tap or push/pull the component with excessive force, otherwise the noise will be eliminated only
temporarily.
feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the J
noise.
placing a piece of paper between components that you suspect are causing the noise.
K
looking for loose components and contact marks.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
REPAIR THE CAUSE
If the cause is a loose component, tighten the component securely.
●
If the cause is insufficient clearance between components:
–
separate components by repositioning or loosening and retightening the component, if possible.
–
insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or urethane tape. A Nissan Squeak and Rattle Kit (J-43980)is available through your authorized Nissan Parts
Department.

conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.

Generic Squeak and Rattle Troubleshooting

EIS000Z2

Refer to Table of Contents for specific component removal and installation information.

INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. The cluster lid A and instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noise. Most of these incidents can be repaired by applying felt cloth tape or silicon spray (in hard to reach areas).Urethane pads can be used to insulate wiring harness.

2002 Q45

SQUEAK AND RATTLE TROUBLE DIAGNOSES
CAUTION:
Do not use silicone spray to isolate a squeak or rattle. If you saturate the area with silicone, you will
not be able to recheck the repair.

CENTER CONSOLE
B

Components to pay attention to include:
1. Shifter assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation procedures also apply to the center console.

DOORS

Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on starts and stops
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks from
the Nissan Squeak and Rattle Kit (J-43980) to repair the noise.

TRUNK

Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
H
1. Trunk lid dumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The trunk lid torsion bars knocking together
BL
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) causJ
ing the noise.

SUNROOF/HEADLINER
Noises in the sunroof/headliner area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headliner and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.

SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seat back lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the conditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noise can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting securing, or
insulating the component causing the noise.

PROCEDURE 1 (WITHOUT CONSULT-II)

SEL170Y

Revision: 2004 April

BL-82

2002 Q45

REMOTE KEYLESS ENTRY SYSTEM
NOTE:
●
If a electronic key is lost, the ID code of the lost electronic key must be erased to prevent unauthorized
use. A specific ID code can be erased with CONSULT-II. However, when the ID code of a lost electronic
key is not known, all controller ID codes should be erased. After all ID codes are erased, the ID codes of
all remaining and/or new remote controllers must be re-registered. To erase all ID codes in memory, register one ID code (electronic key) four times. After all ID codes are erased, the ID codes of all remaining
and/or new electronic keys must be re-registered.
●
When registering an additional electronic key, the existing ID codes in memory may or may not be erased.
If four ID codes are stored in memory, when an additional code is registered, only the oldest code is
erased. If less than four ID codes are stored in memory, when an additional ID code is registered, the new
ID code is added and no ID codes are erased.
●
If you need to activate more than two additional new electronic keys, repeat the procedure “Additional ID
code entry” for each new electronic key.
●
Entry of maximum four ID codes is allowed. When more than four ID codes are entered, the oldest ID
code will be erased.
●
Even if same ID code that is already in the memory is input, the same ID code can be entered. The code
is counted as an additional code.

PROCEDURE 2 (WITH CONSULT-II)
NOTE:
If a electronic key is lost, the ID code of the lost electronic key must be erased to prevent unauthorized use.
When the ID code of a lost electronic key is not known, all controller ID codes should be erased. After all ID
codes are erased, the ID codes of all remaining and/or new remote controllers must be re-registered.

BL-101

2002 Q45

VEHICLE SECURITY (THEFT WARNING) SYSTEM
INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors, hood and trunk lid.
To activate the vehicle security system, BCM must receive signals indicating the doors, hood and trunk lid are
closed and the doors are locked.
When a door is open, BCM terminal No.33, No.37, No.142 or No.143 receives a ground signal from each door
switch.
When a driver door is unlocked, driver door LCU terminal No.6 receives a ground signal from terminal No.2 of
driver door unlock sensor.
When a passenger, rear LH or RH door is unlocked, passenger, rear LH or RH door control unit terminal No.13
receives a ground signal from terminal No.2 of driver door unlock sensor.
When the hood is open, BCM terminal No.122 receives a ground signal
●
from terminal No.1 of the hood switch
●
through body grounds No.E42 and No.E62.
When the trunk lid is open, BCM terminal No.146 receives a ground signal
●
from terminal No.1 of the trunk room lamp switch
●
through body grounds No.B17, No.B57.
When the doors are locked with electronic key and none of the described conditions exist, the vehicle security
system will automatically shift to armed phase.

VEHICLE SECURITY SYSTEM ACTIVATION (WITH KEY OR ELECTRONIC KEY USED TO LOCK
DOORS)
If the emergency key is used to lock doors, LCU01 terminal No.10 receives a ground signal
●
from terminal No.3 of the driver door key cylinder switch.
●
through body grounds No.M24 and No.M114
If this signal or lock signal from electronic key is received by BCM, the vehicle security system will activate
automatically.
Once the vehicle security system has been activated, BCM terminal No.65 supplies ground to terminal No.19
of the security indicator lamp.
The security lamp will illuminate for approximately 30 seconds and then blink.
Now the vehicle security system is in armed phase.

VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by
●
opening a door
●
opening the trunk lid
●
opening the hood
●
unlocking door without using the electronic key.
The vehicle security system will be triggered once the system is in armed phase,
●
when BCM receives a ground signal at terminal No.33, No.37, No.142, No.143 (door switch),
No.146(trunk room lamp switch) or No.122(hood switch)
●
when driver door LCU receives a ground signal at terminal No.6(driver door unlock sensor)
●
when passenger, rear LH, RH door control unit receives a ground signal at terminal No.13(passenger, rear
LH, RH door unlock sensor)
Power is supplied at all times
●
to head lamp relay-1 terminal No.2 and
●
through 15A fuse (No. 56, located in fuse block (J/B) No.1)
●
to horn relay terminal No.2.
When the vehicle security system is triggered, ground is supplied intermittently
●
from BCM terminal No.5(lamp relay) and No.127(horn relay)
●
to head lamp relay terminal No.1 and
●
to horn relay terminal No.1.
The head lamps flash and the horn sounds intermittently.
The alarm automatically turns off after 2 or 3 minutes but will reactivate if the vehicle is tampered with again.

Revision: 2004 April

BL-102

2002 Q45

VEHICLE SECURITY (THEFT WARNING) SYSTEM
VEHICLE SECURITY SYSTEM DEACTIVATION
To deactivate the vehicle security system, a door or the trunk lid must be unlocked with the key or electronic
key.
When the key is used to unlock a door, LCU01 terminal No.9 receives a ground signal
●
from terminal No.1 of the driver door key cylinder switch.
When the emergency key is used to unlock the trunk lid, BCM terminal No.145 receives a ground signal from
terminal No.1 of the trunk lid key cylinder switch.
When the BCM receives either one of these signals or unlock signal from electronic key, the vehicle security
system is deactivated. (Disarmed phase)

PANIC ALARM OPERATION
Remote keyless entry system may or may not operate vehicle security system (horn and head lamps) as
required.
When the Remote keyless entry system is triggered, ground is supplied intermittently.
●
from BCM terminal No.5(lamp relay) and No.127(horn relay)
●
to lamp relay terminal No.1 and
●
to security horn relay terminal No.1.
The head lamp flashes and the horn sounds intermittently.
The alarm automatically turns off after 30 seconds or when BCM receives any signal from electronic key.

System Description

EIS000O3

Every electronic key (including transponder) has its own key ID No. However, only an electronic key with
the key ID registered in the NATS IMMU and ECM can turn ON while inserted in the ignition key cylinder,
allowing the engine to start.
●
An ignition key (electronic key) with straight contour is adopted to prevent the electronic key from vehicle
theft by abuse of duplicated key etc.
●
If the batteries for the vehicle and handheld transmitter are discharged, using the emergency key integrated into the electronic key, the driver/passenger doors and trunk lid can be operated for open/close,
and the steering wheel lock can be unlocked.
NOTE:
The engine cannot be started with an emergency key.
●
If any of ECM, NATS IMMU, steering lock control unit (integrated in the key cylinder) or ignition key (electronic key) has been replaced, or if the trouble diagnosis requires additional registration, mandatory reregistration procedure and registration of the electronic key ID code (if an ignition-key is added) are
required.
NOTE:
All the keys kept by the vehicle owner re-registration of the key ID (electronic key) shall be necessary.
●
If the vehicle owner requires, electronic key ID codes can be registered for up to four keys (including the
electronic key). In this case, the key IDs shall also be registered.
NOTE:
●
The key ID code and remote controller ID code for the key equipped on the vehicle have already been
registered at factory.
●
When conducting registration of key ID at repair, part replacement, and electronic key addition, even the
registered ignition (standard) key shall be registered again. Therefore, collect all the keys from the vehicle
owner.

OUTLINE OF ELECTRONIC KEY OPERATION
Operation 1 (Insert the key into the ignition key cylinder.)
1.

By inserting the ignition key (electronic key: built-in transponder) into the key cylinder, the key detection
switch is turned to ON.
2. The power is supplied from the immobilizer control module → immobilizer antenna amp → antenna coil.
3. The current through the antenna coil induces a magnetic field.
4. The coil in the transponder induces electromotive force by mutual induction, which is charged in the
capacitor.
5. The transponder uses the charged energy to transmit the built-in key ID signal.
6. The sent key ID signal is received by the antenna coil and transmitted via the immobilizer antenna amp to
NATS IMMU.
7. NATS IMMU compares the stored key ID and received one, and only if the matching result is OK, it transmits the key rotation permission signal to the steering lock control unit (integrated in the key cylinder).
8. When the key rotation permission signal is input, the steering lock control unit activates the electronic key
solenoid valve in the key cylinder to allow the electronic key to turn.
9. Turn ignition switch ON.
10. Only if the key ID matching result is OK, the ECM allows the engine to start.

Operation 2 (Withdraw the key from the ignition key cylinder.)
1.
2.

Return the electronic key to the LOCK position of the steering system lock.
When the key is removed, the electronic key solenoid valve in the key cylinder returns to inhibit the key
from turning. In this case, the steering lock control unit processes the key switch ON → OFF signal by
itself to inhibit the electronic key from turning.
NOTE:
If the A/T selector lever is not in "P" position, the electronic key does not return to LOCK position.

NOTE:
If customer reports a “No start” condition, request ALL ELECTRONIC KEY to be brought to the Dealer is case
of a NATS malfunction.

System Description

EIS00129

IVIS (Infinity Vehicle Immobilizer System – NATS) has the following immobilizer functions:
●
Since only IVIS (NATS) electronic keys, whose ID nos. have been registered into the ECM and IMMU of
IVIS (NATS), allow the engine to run, operation of a stolen vehicle without a IVIS (NATS) registered electronic key is pre-vented by IVIS (NATS).
That is to say, IVIS (NATS) will immobilize the engine if someone tries to start it without the registered
electronic key of IVIS (NATS).
●
All of the originally supplied electronic key IDs (except for card key and emergency key) have been IVIS
(NATS) registered. If requested by the vehicle owner, a maximum of four key IDs can be registered into
the IVIS (NATS) components.
●
The security indicator blinks when the ignition switch is in “OFF” or “ACC” position. Therefore, IVIS
(NATS) warns outsiders that the vehicle is equipped with the anti-theft system.
●
When IVIS (NATS) detects any malfunctions, the security indicator lamp lights up while electronic key is in
the “ON” position.
●
IVIS (NATS) trouble diagnoses, system initialization and additional registration of other IVIS (NATS) electronic key IDs must be carried out using CONSULT- ll hardware and CONSULT- ll IVIS (NATS) software.
When IVIS (NATS) initialization has been completed, the ID of the inserted electronic key is automatically
IVIS (NATS) registered. Then, if necessary, additional registration of other IVIS (NATS) electronic key IDs
can be carried out.
Regarding the procedures of IVIS (NATS) initialization and IVIS (NATS) electronic key ID registration,
refer to CONSULT-II operation manual, IVIS/NVIS.

Revision: 2004 April

2002 Q45

IVIS (INFINITI VEHICLE IMMOBILIZER SYSTEM-NATS)
NOTE:
When servicing a malfunction of the IVIS (NATS) indicated by lighting up of Security Indicator Lamp or registering another IVIS (NATS) electronic key ID no., it is necessary to re-register original key identification. Therefore, be sure to receive ALL ELECTRONIC KEYS from vehicle owner.

System Composition

Corrosion Protection

EIS000K4

DESCRIPTION

To provide improved corrosion prevention, the following anti-corrosive measures have been implemented in
NISSAN production plants. When repairing or replacing body panels, it is necessary to use the same anti-corrosive measures.

ANTI-CORROSIVE PRECOATED STEEL (GALVANNEALED STEEL)
To improve repairability and corrosion resistance, a new type of anticorrosive percolated steel sheet has been adopted replacing conventional zinc-coated steel sheet.
Galvannealed steel is electroplated and heated to form Zinc-iron
alloy, which provides excellent and long term corrosion resistance
with cationic electrode position primer.

PIIA0093E

Nissan Genuine Service Parts are fabricated from galvannealed steel. Therefore, it is recommended that
GENUINE NISSAN PARTS or equivalent be used for panel replacement to maintain the anti-corrosive performance built into the vehicle at the factory.

PHOSPHATE COATING TREATMENT AND CATIONIC ELECTRODEPOSITION PRIMER
A phosphate coating treatment and a cationic electrode position primer, which provide excellent corrosion pro- H
tection, are employed on all body components.
CAUTION:
Confine paint removal during welding operations to an absolute
BL
minimum.
J

PIIA0095E

Nissan Genuine Service Parts are also treated in the same manner. Therefore, it is recommended that GENUINE NISSAN PARTS or equivalent be used for panel replacement to maintain anti-corrosive performance built
into the vehicle at the factory.

BODY REPAIR
ANTI-CORROSIVE WAX
To improve corrosion resistance, anti-corrosive wax is applied inside the body sill and inside other closed sections. Accordingly, when replacing these parts, be sure to apply anti-corrosive wax to the appropriate areas of
the new parts. Select an excellent anti-corrosive wax which will penetrate after application and has a long shelf
life.

UNDERCOATING
The underside of the floor and wheelhouse are undercoated to prevent rust, vibration, noise and stone chipping. Therefore, when such a panel is replaced or repaired, apply undercoating to that part. Use an undercoating which is rust preventive, soundproof, vibration-proof, shock-resistant, adhesive, and durable.

Precautions in undercoating

1.
2.
3.
4.

Do not apply undercoating to any place unless specified (such as the areas above the muffler and three
way catalyst which are subjected to heat).
Do not undercoat the exhaust pipe or other parts which become hot.
Do not undercoat rotating parts.
Apply bitumen wax after applying undercoating.

SP130 is the most commonly used HSS.
SP150 HSS is used only on parts that require much more strength.

Revision; 2004 April

BL-190

2002 Q45

BODY REPAIR
Read the following precautions when repairing HSS:
1. Additional points to consider
● The repair of reinforcements (such as side members) by heating is not recommended since it may weaken the component.
When heating is unavoidable, do not heat HSS parts above
550°C (1,022°F).
Verify heating temperature with a thermometer.
(Crayon-type and other similar type thermometer are appropriate.)

D
PIIA0115E

●

When straightening body panels, use caution in pulling any
HSS panel. Because HSS is very strong, pulling may cause
deformation in adjacent portions of the body. In this case,
increase the number of measuring points, and carefully pull
the HSS panel.

H
PIIA0116E

●

When cutting HSS panels, avoid gas (torch) cutting if possible. Instead, use a saw to avoid weakening surrounding areas
due to heat. If gas (torch) cutting is unavoidable, allow a minimum margin of 50 mm (1.97in).

PIIA0117E

●

When welding HSS panels, use spot welding whenever possible in order to minimize weakening surrounding areas due to
heat.
If spot welding is impossible, use M.I.G. welding. Do not use
gas (torch) welding because it is inferior in welding strength.

PIIA0144E

Revision; 2004 April

BL-191

2002 Q45

BODY REPAIR
●

●

The spot weld on HSS panels is harder than that of an ordinary steel panel.
Therefore, when cutting spot welds on a HSS panel, use a
low speed high torque drill (1,000 to 1,200 rpm) to increase
drill bit durability and facilitate the operation.
SP150 HSS panels with a tensile strength of 785 to 981 N/
mm2 (80 to 100 kg/mm2 , 114 to 142 klb/sq in), used as reinforcement in the door guard beams, is too strong to repair.
When these HSS parts are damaged, the outer panels also
sustain substantial damage; therefore, the assembly parts
must be replaced.

PIIA0145E

Precautions in spot welding HSS
This work should be performed under standard working conditions. Always note the following when spot welding HSS:
● The electrode tip diameter must be sized properly according
to the metal thickness.

PIIA0146E

●

The panel surfaces must fit flush to each other, leaving no
gaps.

PIIA0147E

●

Follow the specifications for the proper welding pitch.
