2. Check power window regulator motor operation:
   1. Apply battery voltage to connector terminals 1 and 2.
      NOTE: Do not apply battery voltage to any terminals except terminals 1 and 2.
   2. Check that the motor gear rotates smoothly as follows.

      OK

      Measurement Condition	Specified Condition
      Battery positive (+) → 1 Battery negative (-) → 2	Motor gear rotates clockwise
      Battery positive (+) → 2 Battery negative (-) → 1	Motor gear rotates counterclockwise

3. Check PTC operation:
   NOTE: This check must be performed with the power window regulator and door glass installed on the vehicle.
   1. Install the power window regulator motor assembly (front passenger side). Refer to INSTALLATION .
   2. Connect an electrical tester DC 400 A probe to the wire harness of terminal 2.
