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).

FRONT WIPER HI OPERATION

• 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 AUTO OPERATION

Rain Detection

Rain level and sensor conditions are detected by light & rain sensor.
• BCM transmits the vehicle conditions (vehicle speed, front wiper condition, light & rain sensor sensitivity set-

ting, etc.) to the light & rain sensor via the light & rain sensor serial link.

• Light & rain sensor judges a wiping speed for front wiper by rain condition and the vehicle conditions. And it

transmits the wiping speed request signal to the BCM via the light & rain sensor serial link.

Auto Wiping Operation 

• BCM receives the wiping speed request signal from the light & rain sensor via the light & rain sensor serial

link.

• BCM controls front wiper operation according to the wiping speed request signal. And it transmits the front

wiper request signal (LOW or HIGH) to the IPDM E/R via CAN communication line.

Front wiper AUTO operating condition

- Ignition switch ON
- Front wiper switch AUTO
NOTE:
When the front wiper switch is turned to AUTO position, front wiper operates once regardless of rainy condi-
tions.

Light & rain Sensor Sensitivity Setting

BCM determines light & rain sensor sensitivity according to wiper volume dial position.

NOTE:
Factory setting of the light & rain sensor operation is operation linked with light & rain sensor. Light & rain sen-
sor operation can be set to operation linked or not linked with light & rain sensor using CONSULT. Refer to

WW-23, "WIPER : CONSULT Function - WIPER"

.

NOTE:
When the wiper volume dial position is turned up by 1 level under front wiper AUTO operating condition, front
wiper operates once.

Splash mode operation

Front wiper is operated at HI regardless of the wiper volume adjustment position, when water drops are instan-
taneously sprayed over the windshield glass due to water splash from oncoming vehicles or other causes.
After that, AUTO operation is performed depending on the amount of water drops.

SYSTEM

• Front wiper switch AUTO
• Ignition switch ON
NOTE:
Splash mode is not operated and auto wiping operation is performed, while the vehicle is stopped.

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.

BCM

Fail-safe Control By Light & Rain Sensor Malfunction

BCM detects the light & rain sensor serial link error and the light & rain sensor malfunction.
BCM controls the following fail-safe when light & rain sensor has a malfunction.
• Front wiper switch AUTO and sensing rain drop: The condition just before the activation of fail-safe is main-

tained until the front wiper switch is turned OFF.

• Front wiper switch AUTO and not sensing rain drop: Front wiper is LO operation until the front wiper switch is

turned off.
