FRONT WIPER AND WASHER SYSTEM WW-5 < FUNCTION DIAGNOSIS > C D E F G H I J K M A B WW N O P • BCM transmits the front wiper request signal (INT) to IPDM E/R with CAN communication according to the front wiper INT operation condition and the intermittent operation delay interval judged value. Front wiper INT operating condition - Ignition switch ON Intermittent operation delay interval judgment - BCM calculates the intermittent operation delay interval from the vehicle speed signal received from the wiper dial position and the combination meter with CAN communication. • IPDM E/R turns the integrated front wiper relay ON 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 stop position signal received from IPDM E/R with CAN communication. • BCM transmits the front wiper request signal (INT) again after the intermittent operation delay interval after the front wiper motor is stopped. FRONT WIPER AUTO STOP OPERATION • BCM stops transmitting the front wiper request signal when the front wiper switch is turned OFF. motor position (stop position/except stop position).
