Description

BCM

• Judges 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

System Description

OUTLINE

The rear wiper is controlled by each function of BCM.

Control by BCM

• Combination switch reading function
• Rear wiper control function

REAR WIPER BASIC OPERATION

• BCM detects the combination switch condition by the combination switch reading function.
• BCM controls the rear wiper to start or stop.

REAR WIPER ON OPERATION

• BCM supplies power to the rear wiper motor according to the rear wiper ON operating condition.

Rear wiper ON operating condition

- Ignition switch ON
- Rear wiper switch ON

REAR WIPER INT OPERATION

• BCM supplies power to the rear wiper motor according to the INT operating condition.

Rear wiper INT operating condition

- Ignition switch ON
- Rear wiper switch INT
• BCM controls the rear wiper to operate once.
• BCM detects the rear wiper motor stopping position.
• BCM supplies power to the rear wiper motor after an intermittent from the stop of the rear wiper motor.

REAR WIPER AUTO STOP OPERATION

• BCM stops supplying power to the rear wiper motor when the rear wiper switch is turned OFF.

• BCM reads a stop position 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 3
times.

Washer linked operating condition of rear wiper

- Ignition switch ON
- Rear washer switch ON (0.4 second or more)
• The washer pump is grounded through the combination switch with the rear washer switch ON.

SAFE OPERATION

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

BCS-

80, "Fail-safe"
