If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to dupli-
cate 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. With brakes appllied, place A/T shift selector in drive position.
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. 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 and mechanics stethoscope).
2. Narrow down the noise to a more specific area and identify the cause of the noise by:
• 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.
• 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 tem-
porarily.
• feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the
noise.
• placing a piece of paper between components that you suspect are causing the noise.
• looking for loose components and contact marks. Refer to RF-46, "
Generic Squeak and Rattle Troubleshooting".
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 loos ening 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 av ailable through your authorized Nissan Parts Depart-
ment.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
NOTE:
Always check with the Parts Department for the latest parts information.

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 TroubleshootingINFOID:0000000005286314
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 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 silicone 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 ar ea 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

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 wh ile 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:
1. Trunk lid bumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket

• Intelligent Key has 2 IDs (for Intelligent Key and for NATS). It can perform the door lock/unlock operation and
the engine start operation when the registered Intelligent Key is carried.
• When the Intelligent Key battery is discharged, it can be used as emergency back-up by inserting the
mechanical key set in the Intelligent Key to the ignition key cylinder. At that time, perform the NATS ID verifi-
cation. If it is used when the Intelligent Key is carried, perform the Intelligent Key ID verification.
• If the ID is successfully verified, and when the igniti on knob switch is pressed, steering lock will be released
and initiating the engine will be possible.
• The door lock/unlock operation can be performed when t he Intelligent Key battery is discharged, by operat-
ing the driver door key cylinder using the mechanical key set in the Intelligent Key.
• Up to 4 Intelligent Keys can be registered (including the standard Intelligent Key) on request from the owner.
NOTE:
• Refer to DLK-21, "
INTELLIGENT KEY : S ystem Description" for any functions other than engine start func-
tion of Intelligent Key system.
PRECAUTIONS FOR INTELLIGENT KEY SYSTEM
• For vehicles equipped with the In telligent Key system, the transponder [the chip for NATS ID verifi-
cation] is integrated into the Inte lligent Key. Therefore, the Intelligent Key alone is capable of provid-
ing security clearance for the engine to start. Al so, when the mechanical key alone is inserted into
the key cylinder, performs the NATS ID verification to allow the engine to start. For vehicles without
Intelligent Key system, the transponder is integrated into the mechanical key which must be inserted
into the key cylinder to perform the NATS ID verification to allow the engine to start.
OPERATION WHEN INTELLIGENT KEY IS CARRIED
1. When the ignition knob switch is ON, the Intelligent Key unit transmits the request signal to the Intelligent
Key.
2. The Intelligent Key receives the request signal and transmits the Intelligent Key ID signal to the Intelligent Key unit.
3. The Intelligent Key unit receives the Intelligent Ke y ID signal and verifies it with the registered ID.
4. Intelligent Key unit transmits the steering lock/unlock signal to steering lock solenoid if the verification
results are OK. For detail of key warning message operation, refer to DLK-38, "
System Description".
5. Release of the steering lock.
6. BCM transmits the starter request signal via CAN communication to IPDM E/R and turns the starter relay in IPDM E/R ON if BCM judges that the engine start condition is satisfied.
7. IPDM E/R turns the starter control relay ON when receiving the starter request signal.
8. When shift position is in P or N position, battery power is supplied through the starter relay and operate the starter motor and to start the cranking.
CAUTION:
If a malfunction is detected in the Intelligen t Key system, the “KEY” warning message will be dis-
played in the combination meter. At th at time, the engine cannot be started.
OPERATION RANGE
Engine can be started when Intelligent Key is inside the vehicle. However, sometimes engine might not start
when Intelligent Key is on instrument panel or in glove box.
OPERATION WHEN MECHANICAL KEY IS USED
When the Intelligent Key battery is discharged, performs the NATS ID verification between the integrated tran-
sponder and BCM by inserting the mechanical key into the key cylinder, and then the engine can be started.
For details relating to starting the engine using mechanical key, refer to SEC-14, "
System Description".
STEERING LOCK OPERATION
Steering is locked by steering lock solenoid when ignition switch is in the LOCK position (the ignition knob is
released) and key switch is OFF (key is removed from ignition key cylinder).
