< SYSTEM DESCRIPTION >

SYSTEM

FRONT WIPER INT OPERATION

• BCM transmits the front wiper request signal (INT) to IPDM E/R via CAN communication depending on the

front wiper INT operating condition and intermittent operation delay interval according to the wiper intermit-

tent dial position.

Front wiper INT operating condition

- Ignition switch ON

- Front wiper switch INT

• IPDM E/R turns ON the integrated front wiper relay 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 via CAN communication.

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

NOTE:

Factory setting of the front wiper intermittent operation is operation not linked with vehicle speed. Front wiper

intermittent operation can be set to operation linked or not linked with vehicle speed using CONSULT. Refer to

WW-14, "WIPER : CONSULT Function - WIPER"

.

Front wiper intermittent operation with vehicle speed

• BCM calculates the intermittent operation delay interval from the following

- Vehicle speed signal 

- Wiper intermittent dial position

Unit: Second

*: When operation setting is not linked with vehicle speed. 

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 stop position signal from the front wiper motor and detects the front wiper

motor position (stop position/except stop position).

• 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 via 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 2 times

when the front washer switch OFF is detected.

Washer linked operating condition of front wiper

- Turn 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 washer pump is grounded through the combination switch with the front washer switch ON.

FRONT WIPER SERVICE POSITION OPERATION

When front wiper switch MIST is operated 2 times within 0.47 second, front wiper operates at LO and stops so

that front wiper can be locked back without interfere the hood.

Within 1 Minute After Turning Ignition Switch Off

Front wiper operates at LO and stops if all following conditions are satisfied. 

• Front wiper switch OFF

• Front wiper is in stop position

• Front wiper switch MIST is operated 2 times (Within 0.47 second)

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.)

During Ignition Switch Is On

Front wiper operates at LO and stops if all following conditions are satisfied. 

• Front wiper switch OFF

• Front wiper is in stop position

• Front wiper switch MIST is operated 2 times (Within 0.47 second)

Front wiper returns to stop position when front wiper switch is operated.

WIPER LINKED AUTO LIGHTING FUNCTION

When lighting switch is in the AUTO position, front wiper operates, and then headlamp ON. Refer to 

EXL-12,

"AUTO LIGHT SYSTEM : System Description"

 (Xenon type headlamp) or 

EXL-124, "AUTO LIGHT SYSTEM :

System Description"

 (Halogen type headlamp)

FRONT WIPER AND WASHER SYSTEM : Fail-Safe

INFOID:0000000012197041

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.

< SYSTEM DESCRIPTION >

SYSTEM

If No CAN Communication Is Available With BCM

IPDM E/R detects front wiper stop position by a front wiper stop position signal.

When a front wiper stop position signal is in the conditions listed below, IPDM E/R stops power supply to wiper

after repeating a front wiper 10 seconds activation and 20 seconds stop.

NOTE:

This operation status can be confirmed on the IPDM E/R “Data Monitor” that displays “BLOCK” for the item

“WIP PROT” while the wiper is stopped.

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

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 activated 

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

• Returns automatically wiper to stop position when ignition switch is turned ON if fail-safe control is activated 

while front wiper motor is operated and wiper stop in the other position than stop position.

• The status is held at service position if the fail-safe control is activated while the service position function is 

operating.

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 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 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.

INFOID:0000000012197044

REAR WIPER MOTOR PROTECTION

BCM detects the rear wiper stopping position according to the rear wiper stop position signal.

When the rear wiper stop position signal does not change for more than 5 seconds while driving the rear

wiper, BCM stops power supply to protect the rear wiper motor.
