OUTLINE

The front wiper is controlled by each function of BCM and IPDM E/R.

Control by BCM

• Combination switch reading function
• Front wiper control function

Control by IPDM E/R

• Front wiper control function
• Relay control function

FRONT WIPER BASIC OPERATION

• BCM detects the combination switch condition by the combination switch reading function.
• BCM transmits the front wiper request signal to IPDM E/R via CAN communication depending on each oper-

ating condition of the front wiper.

• IPDM E/R turns ON/OFF the integrated front wiper relay and the front wiper HI/LO relay according to the

front wiper request signal. IPDM E/R provides the power supply to operate the front wiper HI/LO operation.

FRONT WIPER LO OPERATION

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

front wiper LO operating condition.

Front wiper LO operating condition

- Ignition switch ON
- Front wiper switch LO or front wiper switch MIST (while pressing)
• IPDM E/R turns ON the integrated front wiper relay according to the front wiper request signal (LOW).

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

front wiper HI operating condition.

Front wiper HI operating condition

- Ignition switch ON
- Front wiper switch HI
• IPDM E/R turns ON the integrated front wiper relay and the front wiper HI/LO relay according to the front

wiper request signal (HIGH).

FRONT WIPER INT OPERATION

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

front wiper INT operating condition and intermittent operation delay interval according to the wiper volume
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 (LOW) and front wiper request signal (RETURN).

• 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 (LOW) again after the intermittent operation delay interval.
NOTE:
Front wiper INT operation can be set to operation linked or not linked with vehicle speed using CONSULT.
Refer to 

WW-23, "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 volume dial position

Intermittent operation delay Interval

Unit: Second

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

FRONT WIPER AUTO STOP OPERATION

• 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, 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).
• For models without around view monitor: The washer pump is grounded through the combination switch with

the front washer switch ON.

• For models with around view monitor: Pump control unit detects front window washer switch signal from

combination switch and controls the washer pump.

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-23, "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 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.)

IPDM E/R

If No CAN Communication Is Available With BCM

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/
activates the fail-safe.

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.
