- Front washer switch OFF
• BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication so that the front

wiper operate once three seconds after front wiper operation linked with washer.

• IPDM E/R turns ON the integrated front wiper relay according to the front wiper request signal (LO).

SAFE OPERATION

• IPDM E/R performs the fail-safe function when the front wiper auto stop circuit is malfunctioning. Refer to

WW-52, "Fail Safe"

.

• BCM performs fail-safe operation when light and rain sensor (if equipped) or light and rain sensor-related

systems are malfunctioning. Refer to 

EXL-55, "Description"

.

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
(Wiper and washer 
switch)

Refer to 

WW-4, "System Diagram"

.

Combination meter

Transmits the vehicle speed signal to BCM with CAN communication.

Light and rain sensor (if 
equipped)

Detects water droplets on the windshield with infrared rays, and transmits the rain sensor signal 
to BCM through the light and rain sensor serial link.

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 LINKED WITH VEHICLE SPEED

• 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.

< FUNCTION DIAGNOSIS >

REAR WIPER AND WASHER SYSTEM

• 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)
• Washer pump 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.
