PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951588
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service t he system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied 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 Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 three mi nutes before performing any service.
Precaution for Procedure without Cowl Top CoverINFOID:0000000009464598
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.

1. Combination meter 2. BCM (v iew with combination meter
removed) 3. IPDM E/R
4. Combination switch (wiper and wash- er switch) 5. Front wiper motor (with the wiper cowl re-
moved) 6. Front washer motor (with front
bumper removed)
7. Rear view camera washer control unit* (with rear trunk finisher removed)
Part Description
Combination meter Transmits the vehicle speed signal to BCM with CAN communication.
BCM • Judges the switch status by the combination switch reading function.
• Requests (with CAN communication) the front wiper relay and the front wiper high
relay ON to IPDM E/R.
IPDM E/R • Controls the integrated relay according to the request (with CAN communication)
from BCM.
• Performs the auto stop control of the front wiper.
• Supplies power to the rear view camera washer control unit.
Combination switch
(Wiper and washer switch) • Provides input for wiper and washer control to the BCM.
• Refer to WW-6, "System Description"
.
• Supplies signal to the rear view camera washer control unit.
Front washer motor Washer fluid is sprayed according to combination switch signal.
Front wiper motor • IPDM E/R controls front wiper operation.
• Front wiper stop position is transmitted to IPDM E/R.
Rear view camera washer control unit
(with rear view ca mera wash system) • Judges the signal status from the combination switch for washer operation.
• Supplies signal to the front washer motor.

OUTLINE
The front wiper is controlled by each function of BCM and IPDM E/R.
Control by BCM
• Combination switch reading function
• Front wiper control function
Control by IPDM E/R
• Front wiper control function
• Relay control function
FRONT WIPER BASIC OPERATION
• BCM detects the combination switch conditi on by the combination switch reading function.
• BCM transmits the front wiper request signal to IPDM E/R with CAN communication depending on each
operating condition of the front wiper.
• IPDM E/R turns ON/OFF the integrated front wiper rela y and the front wiper high relay according to the front
wiper request signal. IPDM E/R provides the power supply to operate the front wiper HI/LO operation.

• BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication according to the
front wiper LO operating condition.
Front wiper LO operating condition- Ignition switch ON
- Front wiper switch LO or front wiper switch MIST (while pressing)
• IPDM E/R turns ON the integrated front wiper rela y according to the front wiper request signal (LO).
FRONT WIPER HI OPERATION
• BCM transmits the front wiper request signal (HI) to IPDM E/R with CAN communication according to the
front wiper HI operating condition.
Front wiper HI operating condition
- Ignition switch ON
- Front wiper switch HI
• IPDM E/R turns ON the integrated front wiper relay and the front wiper high relay according to the front wiper
request signal (HI).
FRONT WIPER INT OPERATION
• BCM transmits the front wiper request signal (INT ) to IPDM E/R with CAN communication depending on the
front wiper INT operating condition and intermittent operati on delay interval according to the wiper intermit-
tent dial position.
Front wiper INT operating condition
- Ignition switch ON
- Front wiper switch INT
• IPDM E/R turns ON the integrated front wiper relay so that the front wiper is operated only once according to
the front wiper request signal (INT).
• BCM detects stop position/except stop position of the front wiper motor according to the front wiper auto stop
signal received from IPDM E/R with CAN communication.
• BCM transmits the front wiper request signal (INT) again after the intermittent operation delay interval.
NOTE:
Front wiper intermittent operation can be set to the operation with vehicle speed by CONSULT. Refer to BCS-
20, "WIPER : CONSULT Function (BCM - WIPER)".
Front wiper intermittent operation with vehicle speed
• BCM calculates the intermittent operation delay interval from the following
- Vehicle speed signal (received from the combination meter with CAN communication)
- Wiper intermittent dial position

SYSTEM
*: When without vehicle speed setting
FRONT WIPER AUTO STOP OPERATION
• BCM stops transmitting the front wiper request signal when the front wiper switch is turned OFF.
• IPDM E/R detects the front wiper auto stop signal fr om the front wiper motor and detects the front wiper
motor position (stop position/except stop position).
• When the front wiper request signal is stopped, IPDM E/R turns ON the front wiper relay until the front wiper
motor returns to the stop position.
NOTE:
• BCM stops the transmitting of the front wi per request signal when the ignition switch OFF.
• IPDM E/R turns the front wiper rela y OFF when the ignition switch OFF.
FRONT WIPER OPERATION LINKED WITH WASHER
• BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication according to the
washer linked operating condition of the front wiper.
• BCM transmits the front wiper request signal (LO) so that the front wiper operates approximately 2 times
when the front washer s witch OFF is detected.
Washer linked operating condition of front wiper- Ignition switch ON
- Front washer switch ON (0.4 second or more)
• IPDM E/R turns ON the integrated front wiper rela y according to the front wiper request signal (LO).
• The front washer motor is grounded through the combinat ion switch when the front washer switch is ON.
REAR VIEW CAMERA WASHER CONTROL UNIT (if equipped)
• Rear view camera washer control unit detects the co mbination switch condition by the combination switch
reading function.
• Rear view camera washer control unit supplies power and ground to operate the front washer motor.
