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.

*: 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.
