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 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. FRONT WIPER 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 relay 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 (LINKED WITH VEHICLE SPEED) ALLIA0427GBFRONT WIPER AND WASHER SYSTEM WW-5C 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 - Front wiper switch INT 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.  IPDM E/R detects the front wiper auto stop signal from the front wiper motor and detects the front wiper motor position (stop position/except stop position). Wiper intermittent dial posi- tion Intermittent operation interval Intermittent operation delay Interval (s) Vehicle speed Vehicle stopped or less than 5 km/h (3.1 MPH) 5 km/h (3.1 MPH) or more or less than 35 km/h (21.7 MPH) 35 km/h (21.7 MPH) or more or less than 65 km/h (40.4 MPH) 65 km/h (40.4 MPH) or more 1S h o r t ↑ ↓ Long 0.8 0.6 0.4 0.24 2 4321 . 2 31 0 7 . 5 53 41 6 1 2 8 4 . 8 5 2 41 81 27 . 2 6 3 22 41 69 . 6 7 4 23 1 . 52 11 2 . 6 JPLIA0094GBWW-6FRONT WIPER AND WASHER SYSTEM  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 wiper request signal when the ignition switch is OFF.  IPDM E/R turns the front wiper relay OFF when the ignition switch is 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 3 times when the front washer switch 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 relay according to the front wiper request signal (LO).  The front and rear washer motor is grounded through the combination switch with the front washer switch ON. FRONT WIPER DROP WIPE OPERATION  BCM controls the front wiper to operate once according to the conditions of front wiper drop wipe operation. Front wiper drop wipe operating condition - Ignition switch ON - Front wiper switch OFF - Front washer switch OFF  BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication so that the front wiper operate once three seconds after front wiper operation linked with washer.  IPDM E/R turns ON the integrated front wiper relay according to the front wiper request signal (LO). FRONT WIPER FAIL?SAFE OPERATION  IPDM E/R performs the fail-safe function when the front wiper auto stop circuit is malfunctioning. Refer to WW-40, “Fail Safe“.

ALLIA0271GB JPLIA0165GBREAR WIPER AND WASHER SYSTEM WW-9C D E F G H I J K M A B WW N O P  BCM reads an auto stop signal from the rear wiper motor to detect a rear wiper motor position.  When the rear wiper motor is at other than the stopping position, BCM continues to supply power to the rear wiper motor until it returns to the stopping position. NOTE: BCM stops supplying power to the rear wiper motor when the ignition switch is turned OFF. REAR WIPER OPERATION LINKED WITH WASHER  BCM supplies power to the rear wiper motor according to the washer linked operating condition of rear wiper. When the rear washer switch is turned OFF, BCM controls rear wiper to operate approximately three times. Washer linked operating condition of rear wiper - Ignition switch ON - Rear washer switch ON (0.4 second or more)  Front and rear washer motor becomes grounded through the combination switch when the rear washer switch is turned ON.
