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

front wiper INT operation condition and the intermittent operation delay interval judged value.

Front wiper INT operating condition

- Ignition switch ON

- Front wiper switch INT

Intermittent operation delay interval judgment

- BCM calculates the intermittent operation delay interval from the vehicle speed signal received from the

wiper dial position and the combination meter with CAN communication.

• IPDM E/R turns the integrated front wiper relay ON so that the front wiper is operated only once according to

the front wiper request signal (INT).

• BCM detects stop position/except stop position of the front wiper motor according to the front wiper stop

position signal received from IPDM E/R with CAN communication.

• BCM transmits the front wiper request signal (INT) again after the intermittent operation delay interval after

the front wiper motor is stopped.

FRONT WIPER AUTO STOP OPERATION

• BCM stops transmitting the front wiper request signal when the front wiper switch is turned OFF.

• IPDM E/R detects the front wiper auto stop signal from the front wiper motor and detects the front wiper

motor position (stop position/except stop position).

FRONT WIPER AND WASHER SYSTEM

• When the front wiper request signal is stopped, IPDM E/R turns ON the front wiper relay until the front wiper

motor returns to the stop position.

NOTE:

• BCM stops the transmitting of the front wiper request signal when the ignition switch is OFF.

• IPDM E/R turns the front wiper relay OFF when the ignition switch is OFF.

FRONT WIPER OPERATION LINKED WITH WASHER

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

washer linked operating condition of the front wiper.

• BCM transmits the front wiper request signal (LO) so that the front wiper operates approximately 3 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 (LO).

• The front and rear washer motor 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 (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).

FRONT WIPER FAIL

−

SAFE OPERATION

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

PCS-20, "Fail Safe"

.

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 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 (wiper and washer 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.
