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 operating condition of the front wiper.
Front wiper motor transmits the front wiper position signal to IPDM E/R.
IPDM E/R operates ON/OFF of front wiper main relay, front wiper HI/LO relay, and wiper reverse relay according to front wiper request signal and front wiper position signal. Rotation direction, ON/OFF of wiper motor, and HI/LO operation of front wiper are controlled by IPDM E/R.
