On-Vehicle Inspection

  1. INSPECT FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY LH 
    1. Inspect PTC operation inside the power window regulator motor.
      NOTE: The work must be performed with the power window regulator and door glass installed on the vehicle.
      1. Connect an electrical tester DC 400 A probe to the wire harness of terminal 1.
        NOTE: Match the arrow mark on the probe with the direction of the current flow.

      2. Fully close the door glass by pressing the power window UP switch. Wait for approximately 60 seconds.
      3. Continue to press the power window UP switch and measure how long it takes for the electrical current to change from a range of 16 to 28 A to approximately 1 A (Inspection of current shut-off).

        Standard: 4 to 90 seconds 

      4. Check that the door glass moves downward when the power window DOWN switch is pressed.

        If the result is not as specified, replace the power window regulator motor.
