SQUEAK AND RATTLE TROUBLE DIAGNOSES

FELT CLOTHTAPE
Used to insulate where movement does not occur. Ideal for instrument panel applications.
68370-4B000: 15 × 25 mm (0.59 × 0.98 in) pad/68239-13E00: 5 mm (0.20 in) wide tape roll
The following materials, not available through NISSAN Parts Department, can also be used to repair
squeaks and rattles.
UHMW(TEFLON) TAPE
Insulates where slight movement is present. Ideal for instrument panel applications.
SILICONE GREASE
Used in of UHMW tape that will be visible or not fit.
Note: Will only last a few months.
SILICONE SPRAY
Use when grease cannot be applied.
DUCT TAPE
Use to eliminate movement.
CONFIRM THE REPAIR
Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.
Generic Squeak and Rattle TroubleshootingEIS008PS
Refer to Table of Contents for specific component removal and installation information.
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. 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 apply-
ing felt cloth tape or silicon spray (in hard to reach areas). Urethane pads can be used to insulate wiring har-
ness.
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
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 to
repair the noise.

System DescriptionEIS001RR
NATS (Nissan Anti-Theft System) has the following immobilizer functions:

Since only NATS ignition keys, whose ID Nos. have been registered into the ECM and IMMU of NATS,
allow the engine to run, a vehicle operation without registered key in NATS is prevented by NATS.
That is to say, NATS will immobilize the engine if someone tries to start it without the registered key of
NATS.

This version of NATS has dongle unit to improve its anti-theft performance (RHD models). Dongle unit has
its own ID which is registered into NATS IMMU. So if dongle unit is replaced, initialization must be carried
out.

When malfunction of dongle unit is detected:
The security indicator lamp illuminates for about 15 minutes after ignition switch is turned to ON.
–When dongle unit has a malfunction and the indicator lamp is illuminated, engine can not be started. How-
ever engine can be started only one time when security indicator lamp turns off in about 15 minutes after
ignition switch is turned to ON.

All of the originally supplied ignition key IDs have been registered in NATS.
If requested by the vehicle owner, a maximum of five key IDs can be registered into the NATS compo-
nents.

The security indicator blinks when the ignition switch is in “OFF” or “ACC” position. Therefore, NATS
warns outsiders that the vehicle is equipped with the anti-theft system.

When NATS detects trouble, the security indicator lamp lights up as follows.

NATS trouble diagnoses, system initialization and additional registration of other NATS ignition key IDs
must be carried out using CONSULT-II hardware and CONSULT-II NATS software.
When NATS initialzation has been completed, the ID of the inserted ignition key is auto matically registerd
in NATS. Then, if necessary, additional registration of other NATS ignition key IDs can be carried out.
Regarding the procedures of NATS initialization and NATS ignition key ID registration, refer to CONSULT-
II operation manual, NATS.

When servicing a malfunction of the NATS (indicated by lighting up of Security Indicator Lamp) or
registering another NATS ignition key ID No., it may be necessary to re-register original key identi-
fication. Therefore, be sure to receive ALL KEYS from vehicle owner.

NATS (NISSAN ANTI-THEFT SYSTEM)

System CompositionEIS001RS
The immobilizer function of the NATS consists of the following:

NATS ignition key

NATS immobilizer control unit (IMMU) located in the ignition key cylinder

Engine control module (ECM)

Dongle unit (RHD models)

Security indicator
ECM Re-communicating FunctionEIS008F1
Performing following procedure can automatically perform re-communication of ECM and NATS IMMU, but
only when the ECM has been replaced with a new one (*1).
*1: New one means a virgin ECM which has never been energized on-board.
(In this step, initialization procedure by CONSULT-II is not necessary)
NOTE:

When registering new Key IDs or replacing the ECM other than brand new, refer to CONSULT-II
Operation Manual, NATS.

If multiple keys are attached to the key holder, separate them before work.

Distinguish keys with unregistered key ID from those with registered ID.
1. Install ECM.
2. Using a registered key (*2), turn ignition switch to “ON”.
*2: To perform this step, use the key (except for card plate key) that has been used before performing
ECM replacement.
3. Maintain ignition switch in “ON” position for at least 5 seconds.
4. Turn ignition switch to “OFF”.
5. Start engine.
If engine can be started, procedure is completed.
If engine cannot be started, refer to CONSULT-II Operation Manual NATS and initialize control unit.

8. Perform each diagnostic test mode according to each service
procedure.
For further information, see the CONSULT-II Operation Manual,
NATS.
CONSULT-II DIAGNOSTIC TEST MODE FUNCTION
NOTE:

When any initialization is performed, all ID previously registered will be erased and all NATS igni-
tion keys must be registered again.

The engine cannot be started with an unregistered key. In this case, the system may show “DIFFERENCE
OF KEY” or “LOCK MODE” as a self-diagnostic result on the CONSULT-II screen.

When initialization is performed for RHD models, security indicator will flash six times to demonstrate rec-
ognition of the dongle unit ID.

In rare case, “CHAIN OF ECM-IMMU” might be stored as a self-diagnostic result during key registration
procedure, even if the system is not malfunctioning.
