5. CHECK PTC OPERATION
HINT:
PTC operation is a function that prevents overloading of the power window regulator by stopping the motor. PTC operation activates when the power window regulator switch is operated for a predetermined amount of time.

  1. Disconnect the driver side power window regulator motor.

  1. Connect the ammeter's positive (+) lead to terminal 2 of the wire harness side connector and the negative (-) lead to battery's negative terminal.

  1. Connect the battery's positive (+) lead to terminal 1 of the wire harness side connector, and raise that window to the fully closed position.

  1. Continue to apply voltage, and check that the current changes to less than 1A within 4 to 90 seconds.

  1. Disconnect the leads from the terminals.

  1. Approximately 60 seconds later, connect the battery's positive (+) lead to terminal 2 and the negative (-) lead to terminal 1, and check that the window begins to lower.

    NOTICE:
    If the result is not as specified, replace the motor assembly.


6. CHECK JAM PROTECTION FUNCTION (for Driver Side)
HINT:
  1. The jam protection function prevents any part of your body from getting caught by accident between the door frame and the door glass during power window operation.
  2. The jam protection function is only available on the driver side power window.
NOTICE:
If the power window motor has just been reset, raise and lower the door glass several times manually before performing the check.

  1. Check that the door glass lowers by approximately 50 mm (1.97 in.) when something is caught between the door frame and door glass during power window operation. However, when the opening between the door frame and the door glass is less than 200 mm (7.87 in.), the door glass continues to lower and does not stop until an opening of 200 mm (7.87 in.) is achieved.

    Operates during:
    AUTO UP operation


7. CHECK POWER WINDOW FAIL-SAFE FUNCTION (for Driver Side)
The power window regulator motor's pulse sensors detect when an object has been jammed in the window. If a pulse sensor has a malfunction, the fail-safe function starts operating and the AUTO UP / DOWN function disabled.
