IPDM E/R AUTO ACTIVE TEST

1. Start IPDM E/R auto active test. Refer to

PCS-9, "Diagnosis Description"

.

2. Check that the front wiper operates at the LO/HI operation.

WITH CONSULT ACTIVE TEST

1. Select "FRONT WIPER" of IPDM E/R active test item.

2. While operating the test item, check front wiper LO/HI operation and OFF.

Is front wiper operation normal?

YES

>> GO TO 5

NO

>> GO TO 2

2.

CHECK FRONT WIPER MOTOR FUSE

1. Turn the ignition switch OFF.

2. Check that the following fuse is not blown.

Is the fuse blown?

YES

>> Replace the fuse after repairing the affected circuit.

NO

>> GO TO 3

3.

CHECK FRONT WIPER MOTOR GROUND OPEN CIRCUIT

2. Check continuity between front wiper motor harness connector and ground.

Does continuity exist?

YES

>> GO TO 4

NO

>> Repair or replace harness.

4.

CHECK FRONT WIPER MOTOR OUTPUT VOLTAGE

< SYMPTOM DIAGNOSIS >

FRONT WIPER DOES NOT OPERATE

1. Turn the ignition switch ON.

2. Select "FRONT WIPER" of IPDM E/R active test item.

3. With operating the test item, check voltage between IPDM E/R

harness connector and ground.

Is the measurement value normal?

YES

>> Replace front wiper motor. Refer to

WW-55, "Wiper Motor and Linkage"

.

NO

>> Replace IPDM E/R. Refer to

PCS-28, "Removal and Installation of IPDM E/R"

.

5.

CHECK FRONT WIPER REQUEST SIGNAL INPUT

WITH CONSULT DATA MONITOR

1. Select "FR WIP REQ" of IPDM E/R data monitor item.

2. Switch the front wiper switch to HI and LO.

3. With operating the front wiper switch, check the status of "FR WIP REQ".

Is the status of item normal?

YES

>> Replace IPDM E/R. Refer to

PCS-28, "Removal and Installation of IPDM E/R"

.

NO

>> GO TO 6

6.

CHECK COMBINATION SWITCH (WIPER AND WASHER SWITCH)

1. Perform the inspection of the combination switch (wiper and washer switch). Refer to

BCS-47, "Symptom

Table"

.

Is combination switch (wiper and washer switch) normal?

YES

>> Replace BCM. Refer to

PRECAUTION

PRECAUTION

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"

INFOID:0000000010138152

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along

with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain

types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS

system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front

air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.

Information necessary to service the system safely is included in the SR and SB section of this Service Man-

ual.

WARNING:

• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision which would result in air bag inflation, all maintenance must be performed by

an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag

Module, see the SR section.

• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this

Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-

ness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a

hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing

serious injury.

• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the

battery and wait at least three minutes before performing any service.

FRONT WIPER ARM

Front Wiper Arms

INFOID:0000000009480087

REMOVAL AND INSTALLATION

Removal

1. Remove wiper arm covers and wiper arm nuts.
2. Remove front RH wiper arm and front LH wiper arm.
3. Remove front RH and LH blade assembly from the front RH and LH arm.

Installation

1. Operate wiper motor one full cycle, then turn "OFF" (Auto Stop).
2. Clean up the pivot area as shown. This will reduce possibility of

wiper arm looseness.

3. Install front RH and LH blade assembly on the front RH and LH arm.
4. Install front RH wiper arm and front LH wiper arm.
5. Ensure that wiper blades stop within proper clearance. Perform "FRONT WIPER ARM ADJUSTMENT".
6. Tighten wiper arm nuts to specified torque, and install wiper arm covers. Refer to

WW-55, "Wiper Motor

and Linkage"

.

FRONT WIPER ARM ADJUSTMENT

1. Operate wiper motor one full cycle, then turn “OFF” (Auto Stop).
2. Lift the wiper blade up and then rest it onto glass surface, check

the blade clearance (A) and (B).

3. Operate the wiper motor one half cycle so that the wiper arms

are in the upright position and stop arms there, then check the

blade clearances at (C) and (D).

4. Remove wiper arm covers and wiper arm nuts.
5. Adjust front wiper arms on wiper motor pivot shafts to obtain above specified blade clearances.
6. Tighten wiper arm nuts to specified torque, and install wiper arm covers. Refer to

WW-55, "Wiper Motor

and Linkage"

.
