INSPECTION PROCEDURE 3: Windshield Wipers Do Not Stop At The Specified Park Position: Diagnosis

WARNING: This page is about a different car, the 2012 Mitsubishi Lancer. However, it is still accessible from the selected car via links, so may be relevant.

Required Special Tools: 

  1. STEP 1. Check windshield wiper motor connector A-06 for loose, corroded or damaged terminals, or terminals pushed back in the connector. 

    Q: Is windshield wiper motor connector A-06 in good condition? 

    • YES:  Go to Step 2.
    • NO:  Repair or replace the damaged component(s). Refer to HARNESS CONNECTOR INSPECTION . Verify that the windshield wiper works normally.
  2. STEP 2. Check the windshield wiper motor. 
    1. Disconnect windshield wiper motor connector A-06.
    2. Connect the vehicle battery to the windshield wiper motor connector as shown in the illustration, and operate the windshield wiper at low speed. While the windshield wiper is working, disconnect the battery at positions other than the specified park position to stop the windshield wiper motor.
    3. When the battery is connected as shown in the illustration, the motor should run at low speed, and then stop at the specified park position.

      Q: Does the windshield wiper motor operate normally? 

      • YES:  Go to Step 3.
      • NO:  Replace the windshield wiper motor. The windshield wiper should now stop at the specified park position.

  3. STEP 3. Check the ground circuit to the windshield wiper motor. Measure the resistance at the windshield wiper motor connector A-06. 
    1. Disconnect windshield wiper motor connector A-06 and measure the voltage available at the wiring harness side of the connector.
    2. Turn the ignition switch to the "ACC" position.
    3. Measure the voltage between terminal 3 and ground.
      • The voltage should measure approximately 12 volts (battery positive voltage).

        Q: Is the measured voltage approximately 12 volts (battery positive voltage)? 

        • YES:  Go to Step  6.
        • NO:  Go to Step 4.

  4. STEP 4. Check ETACS-ECU connector C-304 for loose, corroded or damaged terminals, or terminals pushed back in the connector. 

    Q: Is ETACS-ECU connector C-304 in good condition? 

  5. STEP 5. Check the wiring harness between ETACS-ECU connector C-304 (terminals 8, 12) and windshield wiper motor connector A-06 (terminals 5, 3). 
    • Check the output lines for open or short circuit.

      Q: Is the wiring harness between ETACS-ECU connector C-304 (terminals 8, 12) and windshield wiper motor connector A-06 (terminals 5, 3) in good condition? 

      • YES:  Go to Step 6.
      • NO:  Repair or replace the damaged component(s). Refer to CABLES AND WIRE CHECK .
  6. STEP 6. Retest the system. 

    Check that the windshield wipers stop at the specified park position.

    Q: Is the check result normal?
