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:0000000005396545
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 noi se. 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 ra ttle. 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 pr ocedures 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 ar eas 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

POWER DOOR LOCK SYSTEM
When the rear door switch LH is ON (door is OPEN), ground is supplied
• to BCM terminal 48
• through rear door switch LH terminal 1
• through rear door switch LH case ground.
When the rear door switch RH is ON (door is OPEN), ground is supplied
• to BCM terminal 13
• through rear door switch RH terminal 1
• through rear door switch RH case ground.
When the back door switch (hatchback) is ON (back door is OPEN), ground is supplied
• to BCM terminal 43
• through back door switch terminals 3 and 4
• through body grounds B117, B132 and D402.
OUTLINE
Functions available by operating the inside door lock and unlock switches
• Interlocked with the locking operation of door lock and unlock switch, door lock actuators of all doors and
trunk (sedan) are locked.
• Interlocked with the unlocking operation of door lock and unlock switch, door lock actuators of all doors and
trunk (sedan) are unlocked.
Functions available by operating t he front door key cylinder switch LH
• Interlocked with the locking operation of front door key cylinder switch LH, door lock actuators of all doors
and trunk (sedan) are locked.
• When front door key cylinder switch LH is unlo cked, front door lock actuator LH is unlocked.
• When front door key cylinder switch LH is unlocked for the second time within 5 seconds after the first oper- ation, door lock actuators on all doors and trunk (sedan) are unlocked.
Key reminder door system
When door lock and unlock switch is operated to lock doors with ignition key inserted in key cylinder and any
door open, all door lock actuators are locked and then unlocked.
AUTOMATIC DOOR LOCKS (LOCK OPERATION)
The interlock door lock function is the function that locks all doors linked with the vehicle speed.
Vehicle Speed Sensing Auto Door Lock*1
All doors are locked when the vehicle speed reaches 24 km/h (15 MPH) or more.
BCM outputs the lock signal to all door lock actuators when it detects that the ignition switch is turned ON, all
doors are closed and the vehicle speed received from the combination meter via CAN communication
becomes 15 MPH (24 km/h) or more.
If a door is opened and closed at any time during one ignition cycle (OFF → ON), even after initial auto door
lock has taken place, the BCM will relock all doors when the vehicle speed reaches 15 MPH (24 km/h) or more
again.
Setting change of Automatic Door Locks (LOCK) Function
The lock operation setting of the autom atic door locks function can be changed.
With CONSULT-III
The ON/OFF switching of the automatic door locks (LOC K) function and the type selection of the automatic
door locks (LOCK) function can be performed at the WO RK SUPPORT setting of CONSULT-III. Refer to BL-
41, "CONSULT-III Function (BCM)".
Without CONSULT- III
The automatic door locks (LOCK) function can be swit ched ON/OFF by performing the following operation.
1. Close all doors (door switch OFF).
2. Turn ignition switch ON.
3. Within 20 seconds of turning the ignition switch ON, press and hold the door lock and unlock switch to the LOCK position for more than 5 seconds.
4. The switching is completed when the hazard lamps blink.
5. The ignition switch must be turned OFF and ON again between each setting change.
OFF → ON : 2 blinks
ON → OFF : 1 blink
