Nissan Maxima. Manual — part 1221
WW-8
< SYSTEM DESCRIPTION >
FRONT WIPER AND WASHER SYSTEM
• 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 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 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 front washer motor is grounded through the combination switch when the front washer switch is ON.
FRONT WIPER FAIL
−SAFE OPERATION
When the front wiper auto stop circuit is malfunctioning, IPDM E/R performs the fail-safe function. Refer to
