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 "FRONT WIPER" of IPDM E/R active test item.
    2. With operating the test item, check that front wiper "LO" and "HI" operation.

      3. Without CONSULT-III

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

    Does front wiper operate normally? 

    Yes: GO TO 5.

    No: GO TO 2.

  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 

    OK: GO TO 3.

    NG: Repair harness or connector.

  3. CHECK GROUND CIRCUIT 

    Check continuity between front wiper motor harness connector E57 terminal 2 and ground.

    2 - Ground : Continuity should exist.

    OK or NG 

    OK: GO TO 4.

    NG: Repair harness or connector.

  4. CHECK IPDM E/R 

    With CONSULT-III

    1. Connect IPDM E/R connector and front wiper motor connector.
    2. Select "FRONT WIPER" of IPDM E/R active test item.
    3. With operating the test item, check voltage between IPDM E/R harness connector and ground.

    31 Stopped Approx. 0 V
    HI operation Battery voltage

    Without CONSULT-III

    1. Connect IPDM E/R connector and front wiper motor connector.
    2. Start up auto active test. Refer to "AUTO ACTIVE TEST ".
    3. Check voltage between IPDM E/R harness connector and ground while front wiper (HI, LO) is operating.

    IPDM E/R connector Terminal
    E7 21 Ground Stopped Approx. 0 V
    LO operation Battery voltage
    31 Stopped Approx. 0 V
    HI operation Battery voltage

    OK or NG 

    OK: Replace front wiper motor.

    NG: Replace IPDM E/R.

  5. CHECK CIRCUIT BETWEEN COMBINATION SWITCH AND BCM 

    With CONSULT-III

    1. Select "FR WIPER INT", "FR WIPER LOW", and "FR WIPER HI" of BCM data monitor item.
    2. With operating the wiper switch, check the monitor status.

      Without CONSULT-III

      Refer to "COMBINATION SWITCH INSPECTION ".

    OK or NG 

    OK: GO TO 6.

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

  6. 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 "CAN COMMUNICATION INSPECTION USING CONSULT-III (SELF-DIAGNOSIS) ".
