SUNROOF SYSTEM
INPUT/OUTPUT SIGNAL CHART
SUNROOF OPERATION
 The sunroof motor assembly is supplied with constant battery power. The BCM supplies power while the
ignition switch is ON or retained power is operating.
 The open & close signals from the sunroof switch enable the sunroof motor to move arbitrarily.
AUTO OPERATION
The sunroof AUTO feature makes it possible to slide open and slide close or tilt up and tilt down the sunroof
without holding the sunroof switch in the slide open/tilt down or slide close/tilt up position.
RETAINED POWER OPERATION
Retained power operation is an additional power supply function that enables the sunroof system to operate
up to 45 seconds after the ignition switch is turned OFF.
Retained power function cancel conditions
 When a front door is opened (door switch ON)
 When ignition switch is turned ON again.
 When 45 seconds elapse on the timer.
ANTI-PINCH FUNCTION
The CPU (central processing unit) of the sunroof motor assembly monitors the sunroof motor operatin and the
sunroof position (fully-closed or other) by signals from the sunroof motor.
When the sunroof motor detects an interruption during the slide close or tilt down operation, the sunroof motor
assembly will reverse to slide open or tilt up.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
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 place 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:0000000001724411
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 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
