   Tester Display	Test Part	Control Range	Diagnostic Note
   Driver Side Power Window	Driver door power window	OFF / UP / DOWN	-

   OK

   Driver door power window operates normally.

   WARNING:

   Be careful to avoid injuries as this test causes vehicle parts to move. During the Active Test, the jam protection function will not operate.

NG → See step   2 

OK → See step   6

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 (D) Battery negative (-) → 2 (U)	Motor gear rotates counterclockwise
      Battery positive (+) → 2 (U) Battery negative (-) → 1 (D)	Motor gear rotates clockwise

      *3	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 (for driver side). Refer to INSTALLATION [08/2012 - ] .
   2. Reconnect the power window regulator master switch connector.
   3. Initialize the power window regulator master switch assembly. Refer to INITIALIZATION [08/2012 - ] .
   4. 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.

   5. Fully close the door glass by pulling up the power window regulator master switch assembly. Wait for approximately 60 seconds.
   6. Continue to pull up the power window regulator master switch assembly 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

   7. Wait for 60 seconds after the previous step, and then press the power window regulator master switch assembly.

      OK

      The driver door window goes down.

NG → See step   5 

OK: Go to next step 

1. Disconnect the power window regulator master switch connector.
2. Disconnect the power window regulator motor assembly (for driver side) connector.
