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.

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-70, "Removal and Installation"
NO
>> Replace IPDM E/R. Refer to
PCS-29, "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-29, "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
.
Is combination switch (wiper and washer switch) normal?
YES
>> Replace BCM. Refer to
BCS-55, "Removal and Installation"
NO
>> Repair or replace the affected parts.

PRECAUTION
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000006247933
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 Instruction. 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 3 minutes before performing any service.
Precaution Necessary for Steering Wheel Rotation After Battery Disconnect
INFOID:0000000006247934
NOTE:
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
• Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″
LOCK
″
position.
• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the
″
ACC
″
position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
