INSULATOR (Light foam block)
80845-71L00: 30 mm (1.18 in) thick, 30×50 mm (1.18×1.97 in)
FELT CLOTHTAPE
Used to insulate where movement does not occur. Ideal for instrument panel applications.
68370-4B000: 15×25 mm (0.59×0.98 in) pad/68239-13E00: 5 mm (0.20 in) wide tape roll
The following materials, not found in the kit, 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. 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 TroubleshootingNIS0021C
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 silicon 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.

POWER WINDOW SYSTEM
Revision: 2007 April2007 M35/M45
ANTI-PINCH SYSTEM
Power window main switch and each power window sub-switch recognizes and controls the door glass condi-
tion by reading encoder signals 1 and 2.
If a door glass is subject to a certain resistance due to a foreign material obstruction during the following close
operation.
automatic close operation when ignition switch is in the “ON” position
automatic close operation during retained power operation
Key cylinder switch close operation during retained power operation
The power window switch reads encoder signal 1, It stops UP operation of the motor, and sends a signal for
down operation to lower the window by a certain amount (150mm, 5.91 in)
INITIALIZATION
Perform the initialization when the following operations are performed or when the auto up operation is not
performed. Refer to GW-63
(Front door), GW-68 (Rear door).
When the power supply to the power window main switch, power window sub-switch or each power win-
dow motor is cut off by the removal of battery terminal or the battery fuse is blown.
Disconnection and connection of power window main switch or each power window sub-switch harness
connector.
Removal and installation of regulator assembly.
Removal and installation of motor from regulator assembly.
Operation of regulator assembly as an independent unit.
Removal and installation of glass.
Removal and installation of door glass run.
CAUTION:
The following operations are not performed under the condition that the initialization is not per-
formed yet.
Auto up operation
Anti-pinch function
Key cylinder switch close operation

FAIL-SAFE CONTROL
The encoder signal detects the up / down speed / detection of door glass. If the malfunction is detected to the
encoder signal or the difference between the glass fully closed position (memorized in power window main
switch or power window sub-switch) and the actual glass position is detected, it shifts into the fail-safe control
It is shifts into the fail-safe control, the initialization is not performed and the following function is not activated
Auto up operation
Anti-pinch function
It is shifts into the fail-safe control, performed the initialization to resume normal operation condition.
POWER WINDOW CONTROL BY THE KEY CYLINDER SWITCH
When ignition key switch is OFF, front power window can be opened or closed by turning the key cylinder
switch UNLOCK / LOCK position more than 1.5 second over condition.
Power window can be opened as the door key cylinder is kept fully turning to the UNLOCK position.
Power window can be closed as the door key cylinder is kept fully turning to the LOCK position.
The power window DOWN stops when the following operations are carried out.
While performing open / close the window, power window is stopped at the position as the door key cylin-
der is placed on NEUTRAL.
When the ignition switch is turned ON while the power window DOWN is operated.
CAN Communication System DescriptionNIS0021H
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNIS0021I

glass fully closed position (memorized in power window main switch or
power window sub-switch) and the actual glass position is detected for
the specified values or more.
Glass recognized position malfunction 2During the glass opening/closing operation, a pulse count is detected that
is above the glass full stroke
Glass fully closed position not updated malfunctionContinuously perform the glass open/close operation (with the glass not
fully closed) at the specified value (approx. 10 time) or more

During the reverse interlock door mirror system, if all of the above conditions are not satisfied, mirror face
returns to original angle.
MIRROR UNGLE MEMORY FUNCTION
During the reverse interlock door mirror operation, the mirror angle can be changed. After adjustment, the
mirror face positions can be memorized (2 positions). For memory setting, Refer to SE-12, "
MEMORY

REVERSE INTERLOCK DOOR MIRROR SYSTEM OPERATION
When the ignition switch is in ON position, A/T control device into R position. Then TCM (in A/T assembly)
detects it and sends the A/T shift position signal to the driver seat control unit via DATA LINE (CAN H,
CAN L).
When selecting either left and right changeover switch, the automatic drive position control unit judges
which door mirror is selected according to the voltage of terminals 2 and 18. And then, it sends the signal
to driver seat control unit via communication signal.
When the driver seat control unit receives the A/T shift position signal and changeover switch signal, it
sends the operation signal to the automatic drive positioner control unit using the communication signal so
that the each mirror sensor voltage stays in a specified value.
Door mirror (RH) selected
Supply the power from terminals 14, 15 and 30 to door mirror (RH) terminals 5, 6 and 7 so that the voltage
of terminals 5 and 21 stays in a specified value. Then, adjust the mirror angle.
Door mirror (LH) selected
Supply the power from terminals 16, 31 and 32 to door mirror (LH) terminals 5, 6 and 7 do that the voltage
of terminals 6 and 22 is the specified value. Then, adjust the mirror angle.
