Description
INFOID:0000000001712175
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.

Description
INFOID:0000000001712176
The front wiper does not operate under any operation conditions.
Diagnosis Procedure
INFOID:0000000001712177
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
CONSULT-III ACTIVE TEST
LO
: Front wiper LO operation
HI
: Front wiper HI operation
OFF
: Stop the front wiper.

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-49, "Removal and Installation"
NO
>> Replace IPDM E/R. Refer to
PCS-30, "Removal and Installation of IPDM E/R"
.
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
PCS-30, "Removal and Installation of IPDM E/R"
.
NO
>> GO TO 6
6.
CHECK COMBINATION SWITCH
1.
Perform the inspection of the combination switch. Refer to
Is combination switch normal?
YES
>> Replace BCM. Refer to
BCS-54, "Removal and Installation"
NO
>> Repair or replace the applicable parts.

PRECAUTION
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001691120
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.
