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 "PG IPDM E/R" to make sure that it is not in fail-safe status.
  1. ACTIVE TEST 

    With CONSULT-III 

    1. Select "IPDM E/R" on CONSULT-III, and select "ACTIVE TEST".
    2. Select "FRONT WIPER" on "SELECT TEST ITEM" screen.
    3. Touch "LO" or "HI" screen.

    Without CONSULT-III 

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

    Does front wiper operate normally? 

    YES: GO TO 2.

    NO: GO TO  4.

  2. CHECK CIRCUIT BETWEEN COMBINATION SWITCH AND BCM 

    With CONSULT-III 

    1. Select "BCM" on CONSULT-III, and select "WIPER" on "SELECT TEST ITEM" screen.
    2. Select "DATA MONITOR". Make sure that "FR WIPER INT", "FR WIPER LOW", and "FR WIPER HI" turn ON-OFF according to wiper switch operation.

    Without CONSULT-III 

    Refer to "COMBINATION SWITCH INSPECTION ".

    OK or NG 

    OK: GO TO 3.

    NG: Check combination switch (wiper switch). Refer to "COMBINATION SWITCH INSPECTION ".

  3. CHECK CIRCUIT BETWEEN IPDM E/R AND BCM 

    Select "BCM" on CONSULT-III, and perform self-diagnosis for "BCM".

    Displayed self-diagnosis results 

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

    CAN COMM CIRCUIT: Check CAN communication line of BCM. Refer to "TROUBLE DIAGNOSIS ".

  4. CHECK GROUND CIRCUIT 
    1. Turn ignition switch OFF.
    2. Disconnect front wiper motor.
    3. Check continuity between front wiper motor connector and ground.

  6. CHECK IPDM E/R 

    With CONSULT-III 

    1. Connect IPDM E/R connector E45.
    2. Turn ignition switch ON.
    3. Select "IPDM E/R" by CONSULT-III, and select "ACTIVE TEST".
    4. Select "FRONT WIPER" on "SELECT TEST ITEM" screen.
    5. Touch "LO" or "HI" screen.
    6. Check voltage between IPDM E/R connector and ground while front wiper (HI, LO) is operating.
