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 with CAN communication depending on each operating condition of the front wiper.
IPDM E/R turns ON/OFF the integrated front wiper relay 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.
