NORMAL OPERATING CONDITION

Description

INFOID:0000000003591484

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.

PCS-11, "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.

With operating the test item, check that front wiper LO/HI operation and OFF.

Does the front wiper operate?

YES

>> GO TO 5.

NO

PRECAUTIONS

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

INFOID:0000000003139006

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 “SRS AIRBAG” and “SEAT BELT” 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 “SRS AIRBAG”.

• 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 Cover

INFOID:0000000003139007

When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
