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

  1. Disconnect the power window regulator motor.

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

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

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

  5. Disconnect the leads from the terminals.

  6. 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 power window regulator motor.
