• BCM transmits the front wiper request signal (RETURN) to IPDM E/R via CAN communication when the

front wiper switch is turned OFF.

• IPDM E/R detects the front wiper stop position signal from the front wiper motor to find out the front wiper

motor position (stop position/except stop position).

• When IPDM E/R receives the front wiper request signal (RETURN) from BCM and the front wiper motor

position is not in the stop position, IPDM E/R turns ON the front wiper relay until the front wiper motor returns
to the stop position.

• When the front wiper motor returns to the stop position, IPDM E/R transmits front wiper status signal to BCM

via CAN communication.

• When BCM receives front wiper status signal from IPDM E/R, BCM transmits the front wiper request signal

(STOP) to IPDM E/R via CAN communication.

FRONT WIPER OPERATION LINKED WITH WASHER

• BCM transmits the front wiper request signal (LOW) to IPDM E/R via CAN communication according to the

washer linked operating condition of the front wiper.

• BCM transmits the front wiper request signal (LOW) 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 (LOW).
• The washer pump is grounded through the combination switch with the front washer switch ON.

FRONT WIPER DROP WIPE OPERATION

• BCM controls the front wiper to operate once according to the conditions of front wiper drop wipe operation.

Front wiper drop wipe operating condition

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

wiper operates once at 3 seconds after front wiper operation linked with washer.

NOTE:
Factory setting of the front wiper drop wipe operation is ON. Front wiper drop wipe operation can be set to ON
or OFF using CONSULT. Refer to 

WW-29, "WIPER : CONSULT Function - WIPER"

.

FRONT WIPER SERVICE POSITION OPERATION

• Front wiper operates at LO and stops so that front wiper can be locked back without interfere the hood.
• BCM transmits the front wiper request signal (LOW) to IPDM E/R via CAN communication for 0.6 seconds

according to the conditions of front wiper service position operation.

Front wiper service position operation conditions (Within 1 minute after turning ignition switch Off)

- Front wiper switch is OFF
- Front wiper is in stop position
- Front wiper switch MIST is operated 2 times (Within 0.47 second)

Front wiper service position operation conditions (During ignition switch is On)

- Front wiper switch is OFF
- Front wiper is in stop position
- Vehicle speed is less than 4 km/h
- Front wiper switch MIST is operated 2 times (Within 0.47 second)
• After the front wiper LO operation, IPDM E/R receives the front wiper request signal (STOP) from BCM and

then stops the front wiper. 

• Front wiper returns to stop position when front wiper switch is operated. (If 1 minute or more is passed after

turning ignition switch OFF, front wiper returns to stop position when ignition switch is turned ON and front
wiper switch is operated.)

When CAN communication with ECM and BCM is impossible, IPDM E/R performs fail-safe control. After CAN
communication recovers normally, it also returns to normal control.

Front Wiper Protection Function

IPDM E/R detects front wiper stop position by front wiper stop position signal.
When front wiper stop position signal is in the condition listed below while the front wiper is operating, IPDM E/
R activates the fail-safe.

SYSTEM DIAGRAM

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

Control part

Fail-safe operation

Front wiper motor

• The status just before activation of fail-safe control is maintained until the ignition switch is turned 

OFF while the front wiper is operating at LO or HI speed.

• The wiper is operated at LO speed until the ignition switch is turned OFF if the fail-safe control is ac-

tivated while the front wiper is set in the AUTO mode and the front wiper motor is operating.

• BCM controls the rear wiper to operate once.
• BCM detects the rear wiper motor stop 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 rear wiper 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 stop 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
