SILICONE GREASE
Used instead 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 TroubleshootingINFOID:0000000003533154
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 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 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 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

AUTOMATIC DRIVE POSITIONER
NOTE:
• Disconnecting the battery erases the stored memory.
• After connecting the battery, insert the key into the ignition cylinder and turn the front door switch LH ON (open)→OFF (close)→ON
(open), the entry/exiting function becomes possible.
• After Exiting operation is carried out, return operation can be operated.
NOTE:
During automatic operation, if the ignition switch is turned ON→START, the automatic operation is suspended. When the ignition switch
returns to ON, it resumes.
FA I L - S A F E M O D E
When any manual and automatic operations are not performed, if any motor operations of seats or pedals are
detected for T2 or more, status is judged “Output error”.
CANCEL OF FAIL-SAFE MODE
The mode is cancelled when the A/T selector lever is shifted to P position from any other position.
NOTE:
The front seat LH position and pedal adjustment functions (see the following table) operate simultaneously in
the order of priority.
*: In conjunction with sliding the seat, the door mirrors are positioned.Function Description
Memory operation The front seat LH, steering wheel, pedals (accelerator, brake) and door mirrors move
to the stored driving position by pushing seat memory switch (1 or 2).
Entry/exit-
ing functionExiting operation At exit, the seat moves backward and the steering wheel raises. (Exiting position)
Entry operationAt entry, the seat and steering wheel return from exiting position to the previous driving
position before the exiting operation.
Keyfob interlock operationPerform memory operation, turnout operation and return operation by pressing keyfob
unlock button.
Auto operation temporary stop
conditions.When ignition switch is turned to START during seat memory switch operation and return
operation, seat memory switch operation and return operation is stopped.
Auto operation stop conditions.• When the vehicle speed becomes 7 km/h (4 MPH) or higher (memory switch operation
and entry operation).
• When the setting switch, seat memory switch 1, or 2 are pressed.
• When A/T selector lever is in any position other than P.
• When the door mirror remote control switch is operated (when ignition switch turned to
ON).
• When power seat switch turned ON.

• through BCM terminal 54
• through BCM terminal 67
• through grounds M57, M61 and M79.
With output circuit 1 power and ground supplied, the rear wiper motor operates in a counterclockwise sweep
direction until auto stop switch 1 closes (full sweep position). Auto stop switch 1 supplies ground
• to BCM terminal 44
• through rear wiper motor terminal 2
• through rear wiper motor terminal 5
• through grounds B117 and B132.
When the BCM receives this ground signal it turns off output circuit 1 and turns on output circuit 2.
Power is supplied to output circuit 2 for reverse operation (clockwise sweep),
• through BCM terminal 54
• to rear wiper motor terminal 6.
Ground is supplied
• to rear wiper motor terminal 4
• through BCM terminal 55
• through BCM terminal 67
• through grounds M57, M61 and M79.
With output circuit 2 power and ground supplied the rear wiper motor operates in a clockwise sweep direction
until auto stop switch 2 closes (full sweep position). Auto stop switch 2 supplies ground
• to BCM terminal 26
• through rear wiper motor terminal 1
• through rear wiper motor terminal 3
• through grounds B117 and B132.
When the BCM receives this ground signal it turns off output circuit 2 and turns on output circuit 1. This pro-
cess repeats until the rear wiper switch or ignition switch is turned off.
If the ignition switch is turned to OFF during operation, the rear wiper motor will immediately stop. If the igni-
tion switch is turned ON after this condition, and the BCM does not receive a rear wiper switch ON or INT sig-
nal, the BCM will operate the rear wiper to the auto stop position.
If the BCM does not receive a change in status in either auto stop switch 1 or auto stop switch 2 within a 5 sec-
ond period of output circuit 1 or output circuit 2 operation, the BCM will turn off output circuit 1 and output cir-
cuit 2.
If the BCM detects the rear door glass ajar signal during rear wiper motor operation, the BCM will operate the
rear wiper motor to the auto stop position. Once the rear door glass ajar signal returns to open (not grounded)
for 5 or more seconds, the BCM will resume rear wiper motor operation.
INTERMITTENT OPERATION
The rear wiper motor operates the wiper arm at low speed approximately every 7 seconds.
When the wiper switch is in the rear wiper INT position, the BCM detects a rear wiper INT request through the
combination switch (wiper switch) reading function.
The BCM controls rear wiper motor operation by switching direction of current flow between the two rear wiper
motor output circuits.
Power is supplied to output circuit 1 for forward operation (counterclockwise sweep),
• through BCM terminal 55
• to rear wiper motor terminal 4.
Ground is supplied
• to rear wiper motor terminal 6
• through BCM terminal 54
• through BCM terminal 67
• through grounds M57, M61 and M79.
With output circuit 1 power and ground supplied, the rear wiper motor operates in a counterclockwise sweep
direction until auto stop switch 1 closes (full sweep position). Auto stop switch 1 supplies ground
• to BCM terminal 44
• through rear wiper motor terminal 2
• through rear wiper motor terminal 5
• through grounds B117 and B132.
When the BCM receives this ground signal it turns off output circuit 1 and turns on output circuit 2.
Power is supplied to output circuit 2 for reverse operation (clockwise sweep),
• through BCM terminal 54
• to rear wiper motor terminal 6.
Ground is supplied
• to rear wiper motor terminal 4
