PRECAUTIONPFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BKS001TD
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 SRS 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 per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS 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
harness connectors.

FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationBKS001TF
System DescriptionBKS001TG

BCM (Body Control Module) controls front wiper low, high and intermittent operation.

IPDM E/R (Intelligent Power Distribution Module Engine Room) operates front wiper motor according to
CAN communication signals from BCM.
Power is supplied at all times

to ignition relay (located in IPDM E/R), from battery direct,

through 50 A fusible link (letter M, located in fuse and fusible link block)

to BCM terminal 55,

through 15 A fuse [No. 17, located in fuse block (J/B)]

to BCM terminal 42,

through 20 A fuse (No. 73, located in IPDM E/R)

to front wiper relay (located in IPDM E/R),

through 15 A fuse (No. 78, located in IPDM E/R)

to CPU (central processing unit) located in IPDM E/R,

through 15 A fuse (No. 71, located in IPDM E/R)

to CPU located in IPDM E/R.
When the ignition switch ON or START position, power is supplied

to ignition relay (located in IPDM E/R),

through 10 A fuse [No. 1, located in fuse block (J/B)]

to BCM terminal 38,

Front Wiper Does Not Return to Stop Position (After Front Wipers Operate for
10 Seconds, They Stop for 20 Seconds, and after repeating the operations five
times, they become inoperative)
BKS001TS
CAUTION:

When auto-stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front
wipers, IPDM E/R considers that front wipers are locked, and stops front wiper output. That
causes this symptom.

This status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIP PROT” item shows
“BLOCK”.
1. CHECK BCM DATA MONITOR
With CONSULT-II
1. Select “BCM” on CONSULT-II, and select “WIPER” on “SELECT TEST ITEM” screen.
2. Select “DATA MONITOR” on “SELECT DIAG MODE” screen.
Make sure that “FR WIPER STOP” turns ON-OFF according to
front wiper operation.
Without CONSULT-II
GO TO 2.
OK or NG
OK >> Replace IPDM E/R. Refer to PG-28, "Removal and
Installation of IPDM E/R" .
NG >> GO TO 2.
2. CHECK CIRCUIT BETWEEN IPDM E/R AND FRONT WIPER MOTOR
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connector and front wiper motor connector.
3. Check continuity between IPDM E/R harness connector (A) and
front wiper motor harness connector (B).
4. Check continuity between IPDM E/R harness connector (A) and
ground.
OK or NG
OK >> GO TO 3.
