Front Wiper Does Not Operate

CAUTION:

During IPDM E/R fail-safe control, front wipers may not operate. Refer to "CAN COMMUNICATION LINE CONTROL " in "Power Supply, Ground & Circuit Elements IPDM E/R" to make sure that it is not in fail-safe status.

ACTIVE TEST
With CONSULT-II
1. Select "IPDM E/R" by CONSULT-II, and select "ACTIVE TEST" on "SELECT DIAG MODE" screen.
2. Select "FRONT WIPER" on "SELECT TEST ITEM" screen.
3. Touch "LO" or "HI" screen.
Without CONSULT-II

Start up auto active test. Refer to "AUTO ACTIVE TEST ".

Does front wiper operate normally?
1. YES : GO TO 3.
2. NO : GO TO 2.
CHECK FRONT WIPER CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connector and front wiper motor connector.
3. Check continuity between IPDM E/R harness connector and front wiper motor harness connector terminal.

OK or NG
1. OK : Replace front wiper motor.
2. NG : Replace IPDM E/R.
CHECK CIRCUIT BETWEEN COMBINATION SWITCH AND BCM
With CONSULT-II
1. Select "BCM" on CONSULT-II, and select "WIPER" on "SELECT TEST ITEM" screen.
2. Select "DATA MONITOR" on "SELECT DIAG MODE" screen. Make sure that "FR WIPER INT", "FR WIPER LOW", and "FR WIPER HI" turn ON-OFF according to wiper switch operation.
Without CONSULT-II

Refer to "COMBINATION SWITCH INSPECTION ".

OK or NG
1. OK : GO TO 6.
2. NG : Check combination switch (wiper switch). Refer to "COMBINATION SWITCH INSPECTION ".

CHECK CIRCUIT BETWEEN IPDM E/R AND BCM
Select "BCM" on CONSULT-II, and perform self-diagnosis for "BCM".

Displayed self-diagnosis results

NO DTC: Replace BCM. Refer to "REMOVAL AND INSTALLATION OF BCM ".
