• BCM reads an auto stop signal from the rear wiper motor to detect a rear wiper motor position.
• When the rear wiper motor is at other than the stopping position, BCM continues to supply power to the rear

wiper motor until it returns to the stopping position.

NOTE:
BCM stops supplying power to the rear wiper motor when the ignition switch is turned OFF.

REAR WIPER OPERATION LINKED WITH WASHER 

• BCM supplies power to the rear wiper motor according to the washer linked operating condition of rear

wiper. When the rear washer switch is turned OFF, BCM controls rear wiper to operate approximately three
times.

Washer linked operating condition of rear wiper

- Ignition switch ON
- Rear washer switch ON (0.4 second or more)
• Front and rear washer motor becomes grounded through the combination switch when the rear washer

switch is turned ON.

REAR WIPER DROP WIPE OPERATION

• BCM controls the rear wiper to operate once according to the rear wiper drop wipe operating condition.

Rear wiper drop wipe operating condition

- Ignition switch ON
- Rear wiper switch OFF
- Rear washer switch OFF
• BCM controls the rear wiper so that it operates once time approximately three seconds later after the washer

interlocking operation of the rear wiper.

REAR WIPER FAIL

SAFE OPERATION

BCM performs the fail-safe function when the rear wiper auto stop circuit is malfunctioning. Refer to 

WW-40,

"Fail Safe"
