NORMAL OPERATING CONDITION
DescriptionINFOID:0000000001366641
FRONT WIPER MOTOR PROTECTION FUNCTION
IPDM E/R may stop the front wiper to protect the front wiper motor if any obstruction (operation resistance)
such as a large amount of snow is detected during the front wiper operation.
At that time turn OFF the front wiper and remove the foreign object. Then wait for approximately 20 seconds
or more and reactivate the front wiper. The wiper will operate normally.
REAR WIPER MOTOR PROTECTION FUNCTION
BCM may stop rear wiper to protect the rear wiper motor when the rear wiper is stopped for 5 seconds or
more due to a snowfall.
Rear wiper operates normally one minute after the obstacles are removed with rear wiper OFF.

The front wiper does not operate under any operation conditions.
Diagnosis ProcedureINFOID:0000000001366643
1. CHECK WIPER RELAY OPERATION
IPDM E/R AUTO ACTIVE TEST
1. Start IPDM E/R auto active test. Refer to PCS-10, "
Diagnosis Description".
2. Check that the front wiper operates at the LO/HI operation.
CONSULT-III ACTIVE TEST
1. Select "FRONT WIPER" of IPDM E/R active test item.
2. While operating the test item, check front wiper operation.
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 applicable circuit.
NO >> GO TO 3
3. CHECK FRONT WIPER MOTOR GROUND OPEN CIRCUIT
1. Disconnect front wiper motor.
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

5. CHECK FRONT WIPER REQUEST SIGNAL INPUT
CONSULT-III 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 xxx.
NO >> GO TO 6
6. CHECK COMBINATION SWITCH
1. Perform the inspection of the combination switch. Refer to BCS-55, "
Symptom Table".
Is combination switch normal?
YES >> Replace BCM. Refer to BCS-57, "Removal and Installation of BCM".
NO >> Repair or replace the applicable parts.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001538893
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. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
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.
Precaution for Procedure without Cowl Top CoverINFOID:0000000001366647
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
