Manual Description
FRONT WIPER MOTOR GROUND CIRCUIT 21, fRONT WIPER AND WASHER SYSTEM 4, cOMMON ITEM : CONSULT Function (BCM COMMON ITEM) 8, wIPER : CONSULT Function (BCM - WIPER) 9.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM) 36, fRONT WIPER AND WASHER SYSTEM 43, fRONT WIPER AUTO STOP SIGNAL CIRCUIT19, fRONT WIPER DOES NOT OPERATE 51.

(SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" 53, verify the symptom with operational check, repair or replace specific parts, fRONT WIPER AND WASHER SYSTEM.

The front wiper is controlled by each function of BCM IPDM E/R, 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 each, iPDM E/R turns ON/OFF the integrated front wiper relay and the front wiper high relay according front.

BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication according, - 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), bCM transmits the front wiper request signal (HI) to IPDM E/R with CAN communication according.

IPDM E/R turns ON the integrated front wiper relay and the front wiper high relay according front wiper, fRONT WIPER INT OPERATION (LINKED WITH VEHICLE SPEED), bCM transmits the front wiper request signal (INT) to IPDM E/R with CAN communication according, front wiper INT operation condition and the intermittent operation delay interval judged value.

- BCM calculates the intermittent operation delay interval from the vehicle speed signal received, 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, the front wiper request signal (INT).

BCM detects stop position/except stop position of the front wiper motor according to 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 stopped.

BCM stops transmitting the front wiper request signal when the front wiper switch turned OFF, iPDM E/R detects the front wiper auto stop signal from the front wiper motor and detects 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 front wiper.

BCM stops the transmitting of the front wiper request signal when the ignition switch OFF, iPDM E/R turns the front wiper relay OFF when the ignition switch OFF, fRONT WIPER OPERATION LINKED WITH WASHER, washer linked operating condition 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 detected, the front washer motor is grounded through the combination switch with the front washer switch ON, bCM controls the front wiper to operate once according to the conditions of front wiper drop wipe operation.

Front wiper drop wipe operating condition, bCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication so that front, wiper operate once three seconds after front wiper operation linked with washer, iPDM E/R performs the fail-safe function when the front wiper auto stop circuit malfunctioning.

BCM (view with instrument lower panel LH removed), with front fender protector RH removed), front wiper motor E23 (view with, judges each switch status by the combination switch reading function.

Requests (with CAN communication) the front wiper relay and the front wiper high relay ON, controls the integrated relay according to the request (with CAN communication) BCM, performs the auto stop control front wiper.
