OK: Go to next step 

1. Remove the front power window regulator motor assembly (for front passenger side) (See REMOVAL  )
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 AND SPECIFIED CONDITION
      
      

      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 front power window regulator motor assembly (for front passenger side) (See INSTALLATION  )
   2. Connect an electrical tester DC 400 A probe to the wire harness of terminal 2
      NOTE: Match the arrow mark of the probe with the direction of the current flow.
   3. Fully close the door glass by pulling up the multiplex network switch assembly (for front passenger side) Wait for approximately 60 seconds.
   4. Continue to pull up the multiplex network switch assembly (for front passenger side) and measure how long it takes for the electrical current to change from a range of 16 to 28 A to approximately 1 A (current shut-off inspection).

      Standard: 4 to 90 seconds 

   5. Wait for 60 seconds after the previous step, and then push down the multiplex network switch assembly (for front passenger side)
