  5. CHECK JAM PROTECTION FUNCTION 

    HINT:

    • The jam protection function helps prevent any part of your body from getting caught by accident between the door frame and the door glass during power window operation.
    • The jam protection function is only available on the driver side power window.
    NOTE: 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. Operative conditions:
      • AUTO UP
      • AUTO UP function after turning power switch OFF
      • MANUAL UP function after turning power switch OFF

  6. CHECK POWER WINDOW FAIL-SAFE FUNCTION 
    1. 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 will be disabled.
  7. 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. Pull up and hold the power window regulator switch for more than 90 seconds. Then release the switch.
    2. Check that pressing the switch does not move the window.
    3. Wait until 60 seconds have passed since the switch was released in the first step. Check that pressing the switch results in normal window movement.
