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 TroubleshootingEIS002Y2
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.

FRONT WIPER AND WASHER SYSTEM
Revision: August 20072004 QX56

BCM detects ON/OFF status of intermittent wiper dial position

BCM calculates operation interval from wiper dial position and vehicle speed signal received through CAN
communications.

BCM sends front wiper request signal (INT) to IPDM E/R at calculated operation interval.
When the IPDM E/R receives a front wiper request signal (INT), it supplies ground to energize the front wiper
relay. It then sends an auto-stop signal to the BCM, and conducts intermittent front wiper motor operation.
AUTO STOP OPERATION
When the wiper arms are not located at the base of the windshield, and the wiper switch is turned OFF, the
wiper motor will continue to operate until the wiper arms reach the windshield base. When the wiper arms
reach the base of windshield, front wiper motor terminals 6 and 1 are connected.
Ground is supplied

to IPDM E/R terminal 43

through front wiper motor terminal 6

through front wiper motor terminal 1

through grounds E9, E15 and E24.
The IPDM E/R sends an auto stop operation signal to the BCM through CAN communication lines.
When the BCM receives an auto stop operation signal, the BCM sends wiper stop signal to the IPDM E/R over
CAN communication lines. The IPDM E/R then de-energizes the front wiper relay.
The wiper motor will then stop the wiper arms at the STOP position.
FRONT WASHER OPERATION
When the ignition switch is in the ON or START position, and the front and rear washer switches are OFF, the
front and rear washer motor is supplied power

through 10A fuse (No. 9, located in the fuse block J/B)

through combination switch (wiper switch) terminal 14

through combination switch (wiper switch) terminal 13

to front and rear washer motor terminal 1, and

through combination switch (wiper switch) terminal 11

to front and rear washer motor terminal 2.
When the front wiper switch is in the front washer position, the BCM detects a front washer signal request
through the combination switch (wiper switch) reading function.
Combination switch ground is supplied

to front and rear washer motor terminal 2

through combination switch (wiper switch) terminal 11

through combination switch (wiper switch) terminal 12

through grounds M57, M61 and M79.
With ground supplied, the front and rear washer motor is operated in the front direction.
When the BCM detects that front washer motor has operated for 0.4 seconds or longer, the BCM uses CAN
communication and sends a wiper request signal to the IPDM E/R for low speed operation of wipers.
When the BCM detects that the washer switch is OFF, low speed operation cycles approximately 3 times and
then stops.
MIST OPERATION
When the wiper switch is temporarily placed in the mist position, wiper low speed operation cycles once and
then stops. For additional information about wiper operation under this condition, refer to WW-5, "
LOW
SPEED WIPER OPERATION" .
If the switch is held in the mist position, low speed operation continues.
FAIL -S AFE F UN CTI ON
The BCM includes fail-safe function to prevent malfunction of electrical components controlled by CAN com-
munications if a malfunction in CAN communications occurs.
The BCM uses CAN communications to stop output of electrical components it controls.
Until the ignition switch is turned off, the front wiper system remains in same status as just before fail-safe con-
trol was initiated. (If wiper was in low speed operation just before fail-safe, it continues low speed operation
until ignition switch is turned OFF.)
When fail-safe status is initiated, the BCM remains in standby until normal signals are received.

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 starts the timing function of 7 sec-
onds. After approximately 7 seconds the BCM turns on output circuit 1. This process repeats until the rear
wiper switch or ignition switch is turned off.
AUTO STOP OPERATION
When the rear wiper switch is turned off, the BCM will continue the cycle of output circuit 1 or output circuit 2
until auto stop switch 1 and auto stop switch 2 are both in the closed position. When the BCM receives ground
signals from auto stop switch 1 and auto stop switch 2 simultaneously, output circuit 1 and output circuit 2 are
both turned off.
REAR WASHER OPERATION
When the ignition switch is in the ON or START position, and the front and rear washer switches are OFF, the
front and rear washer motor is supplied power

through 10A fuse [No. 9, located in the fuse block (J/B)]

through combination switch (wiper switch) terminal 14

through combination switch (wiper switch) terminal 11

to front and rear washer motor terminal 2, and

through combination switch (wiper switch) terminal 13

to front and rear washer motor terminal 1.
When the rear wiper switch is in rear washer position, the BCM detects a rear washer signal by BCM wiper
switch reading function. Combination switch ground is supplied

to front and rear washer motor terminal 1

through combination switch (wiper switch) terminal 13

through combination switch (wiper switch) terminal 12

through grounds M57, M61 and M79.
With ground supplied, the front and rear washer motor is operated in the rear direction.
When the BCM detects that the rear washer motor has operated for 0.4 seconds or longer, BCM operates the
rear wiper motor.
When the BCM detects that the rear washer switch is in OFF, the rear wiper motor cycles approximately 3
times and then stops.
