< SYSTEM DESCRIPTION >

SYSTEM

• 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 power 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 3

times.

Washer linked operating condition of rear wiper

- Power switch ON

- Rear washer switch ON (0.4 second or more)

• The washer motor is grounded through the combination switch with the rear washer switch ON.

• Rear window defogger

• Front wiper motor

• Parking lamp

• License plate lamp

• Tail lamp

• Front fog lamp

• Side marker lamp

• Headlamp (LO, HI)
