SQUEAK AND RATTLE TROUBLE DIAGNOSES
Revision: 2007 April2007 M35/M45
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 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 (electrical load, half-clutch on M/T models, drive position on A/T models).
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
temporarily.

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 SE-7, "
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 loosening and retightening the component, if possible.
–insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or ure-
thane tape. A Nissan Squeak and Rattle Kit (J-43980) is available through your authorized Nissan Parts
Department.
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.
The following materials are contained in the Nissan Squeak and Rattle Kit (J-43980). Each item can be
ordered separately as needed.

INTELLIGENT KEY INTERLOCK OPERATION
When pressing unlock button on Intelligent Key or request switch, the system performs memory operation,
exiting operation and entry operation.
Operation procedure
1. Press unlock button on Intelligent Key or request switch.
2. The system performs MEMORY OPERATION, and then performs EXITING OPERATION continually.
NOTE:
If the seat position is in memorized position before push unlock button, MEMORY OPEPATION dose not per-
form.
3. Turn ignition switch ON or close driver side door when ignition switch is in “ACC” position.
4. The system performs ENTRY OPERATION. (Seat and steering positions are moved to memorized posi-
tions. The memorize position is related to key ID.)
Operation Condition
If the following conditions are not satisfied, memory switch operation is not performed.

Ignition switch is in OFF position.

Driver side power seat switch and door mirror control switch are not operated.

Seat memory switch and set switch are not operated.

Output malfunction is not detected.

CAN and UART communications are normal.

A/T selector lever position is in P position.

Detention position switch malfunction is not detected.
[Detention position switch malfunction is sensed when detention switch remains OFF and vehicle speed is
higher than 7 km/h (4 MPH).]
Linking Intelligent Key to the Stored Memory Procedure
NOTE:

If ignition switch turns ON in the middle of memory operation, the system does not perform exiting opera-
tion after memory operation.

If ignition switch turns ON in the middle of exiting operation, entry operation starts at that time.

If entry / exiting operation is cancelled, perform memory operation only.
FAIL-SAFE MODE
If any of the parts move more than a period “T” without any switch operation, MEMORY OPERATION, EXIT-
ING OPERATION, ENTRY OPERATION, INTELLIGENT KEY INTERLOCK OPERATION and the malfunction
part of manual operations are not operated (output malfunction).
Canceling Fail-safe Mode
The mode is cancelled by either of the following operations.

When the selector lever is shifted to P position from any other position (detention switch is turned OFF).
