Part Description
Combination meter Transmits the vehicle speed signal to BCM with CAN communication.
BCM • Judges the switch status by the combination switch reading function.
• Requests (with CAN communication) the front wiper relay and the front wiper high
relay ON to IPDM E/R.
IPDM E/R • Controls the integrated relay according to the request (with CAN communication)
from BCM.
• Performs the auto stop control of the front wiper.
• Supplies power to the rear view camera washer control unit.
Combination switch
(Wiper and washer switch) • Provides input for wiper and washer control to the BCM.
• Refer to WW-6, "System Description"
.
• Supplies signal to the rear view camera washer control unit.
Front washer motor Washer fluid is sprayed according to combination switch signal.
Front wiper motor • IPDM E/R controls front wiper operation.
• Front wiper stop position is transmitted to IPDM E/R.
Rear view camera washer control unit
(with rear view ca mera wash system) • Judges the signal status from the combination switch for washer operation.
• Supplies signal to the front washer motor.

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 conditi on by the combination switch reading function.
• BCM transmits the front wiper request signal to IPDM E/R with CAN communication depending on each
operating condition of the front wiper.
• IPDM E/R turns ON/OFF the integrated front wiper rela y and the front wiper high relay according to the front
wiper request signal. IPDM E/R provides the power supply to operate the front wiper HI/LO operation.

• BCM transmits the front wiper request signal (LO) to IPDM E/R with 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 rela y according to the front wiper request signal (LO).
FRONT WIPER HI OPERATION
• BCM transmits the front wiper request signal (HI) to IPDM E/R with 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 high relay according to the front wiper
request signal (HI).
FRONT WIPER INT OPERATION
• BCM transmits the front wiper request signal (INT ) to IPDM E/R with CAN communication depending on the
front wiper INT operating condition and intermittent operati on 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 auto stop
signal received from IPDM E/R with CAN communication.
• BCM transmits the front wiper request signal (INT) again after the intermittent operation delay interval.
NOTE:
Front wiper intermittent operation can be set to the operation with vehicle speed by CONSULT. Refer to BCS-
20, "WIPER : CONSULT Function (BCM - WIPER)".
Front wiper intermittent operation with vehicle speed
• BCM calculates the intermittent operation delay interval from the following
- Vehicle speed signal (received from the combination meter with CAN communication)
- Wiper intermittent dial position

*: When without vehicle speed setting
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 fr om 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 wi per request signal when the ignition switch OFF.
• IPDM E/R turns the front wiper rela y OFF when the ignition switch 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 2 times
when the front washer s witch 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 rela y according to the front wiper request signal (LO).
• The front washer motor is grounded through the combinat ion switch when the front washer switch is ON.
REAR VIEW CAMERA WASHER CONTROL UNIT (if equipped)
• Rear view camera washer control unit detects the co mbination switch condition by the combination switch
reading function.
• Rear view camera washer control unit supplies power and ground to operate the front washer motor.
