Infiniti G37 Coupe. Manual — part 1433
WW-6
< FUNCTION DIAGNOSIS >
FRONT WIPER AND WASHER SYSTEM
• 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 operation 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-III. Refer to
WW-11, "WIPER : CONSULT-III 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 unified meter and A/C amp. with CAN communication)
- Wiper intermittent dial position
*: 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 from 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 wiper request signal when the ignition switch OFF.
• IPDM E/R turns the front wiper relay 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 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 washer pump is grounded through the combination switch when the front washer switch ON.

SAFE OPERATION
When the front wiper auto stop circuit is malfunctioning, IPDM E/R performs the fail-safe function. Refer to

Component Description
INFOID:0000000001629606
Part
Description
BCM
• Judges the each 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.
Combination switch
(Wiper & washer switch)
Refer to
Unified meter and A/C amp.
Transmits the vehicle speed signal to BCM with CAN communication.
