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 condition 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 relay 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.
FRONT WIPER 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 relay 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 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 from the front wiper motor and detects the front wiper                                 N
  motor position (stop position/except stop position).
JPLIA0095GB
NOTE:
• BCM stops the transmitting of the front wiper request signal when the ignition switch is OFF.
• IPDM E/R turns the front wiper relay OFF when the ignition switch is 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 3 times
  when the front washer switch 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 relay according to the front wiper request signal (LO).
•   The front washer motor is grounded through the combination switch with the front washer switch ON.
FRONT WIPER DROP WIPE OPERATION
• BCM controls the front wiper to operate once according to the conditions of front wiper drop wipe operation.
Front wiper drop wipe operating condition
- Ignition switch ON
- Front wiper switch OFF
- Front washer switch OFF
• BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication so that the front
  wiper operates once three seconds after front wiper operation linked with washer.
• IPDM E/R turns ON the integrated front wiper relay according to the front wiper request signal (LO).
FRONT WIPER FAIL−SAFE OPERATION
• IPDM E/R performs the fail-safe function when the front wiper auto stop circuit is malfunctioning. Refer to
  PCS-21, "Fail Safe".

  Details of time display
• CRNT: Displays when there is a malfunction now or after returning to the normal condition until turning igni-
  tion switch OFF → ON again.
• 1 - 39: Displayed if any previous malfunction is present when current condition is normal. It increases like 1
  → 2 → 3...38 → 39 after returning to the normal condition whenever ignition switch OFF → ON. The counter
  remains at 39 even if the number of cycles exceeds it. It is counted from 1 again when turning ignition switch
  OFF → ON after returning to the normal condition if the malfunction is detected again.

1. CHECK WIPER RELAY OPERATION
  IPDM E/R AUTO ACTIVE TEST
1.  Start IPDM E/R auto active test. Refer to PCS-11, "Diagnosis Description".                                   E
2.  Check that the front wiper operates at the LO/HI operation.
  WITH CONSULT ACTIVE TEST
1. Select "FRONT WIPER" of IPDM E/R active test item.                                                            F

  YES >> Replace front wiper motor. Refer to WW-55, "Wiper Motor and Linkage".
  NO     >> Replace IPDM E/R. Refer to PCS-29, "Removal and Installation of IPDM E/R".
5. CHECK FRONT WIPER REQUEST SIGNAL INPUT
     WITH CONSULT 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".
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along                                  C
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.                      D
Information necessary to service the system safely is included in the SR and SB section of this Service Man-
ual.
WARNING:                                                                                                                       E
• 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.
                                                                                                                               F
• 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                          G
  Service Manual. 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                                                               H
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                        I
  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                            J
  battery, and wait at least 3 minutes before performing any service.
