2. Measure the voltage according to the value(s) in the table below.

   Standard voltage

   Tester Connection	Condition	Specified Condition
   K2-3 (B) - Body ground	Ignition switch on (IG)	11 to 14 V

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Measure the resistance when the switch is operated according to the value(s) in the table below.

   Standard resistance

   Tester Connection	Switch Condition	Specified Condition
   1 (D) - 2 (SD)	UP	Below 1 Ω
   3 (B) - 4 (U)		Below 1 Ω
   1 (D) - 2 (SD)	OFF	Below 1 Ω
   4 (U) - 5 (SU)		Below 1 Ω
   4 (U) - 5 (SU)	DOWN	Below 1 Ω
   1 (D) - 3 (B)		Below 1 Ω

NG → See step   7 

OK: Go to next step 

1. Disconnect the K2 and K3 connectors.

2. Measure the resistance according to the value(s) in the table below.

   Standard resistance

   Tester Connection	Condition	Specified Condition
   K2-4 (U) - K3-1 (U)	Always	Below 1 Ω
   K2-1 (D) - K3-2 (D)	Always	Below 1 Ω
   K2-4 (U) - Body ground	Always	10 kΩ or higher
   K2-1 (D) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Check power window regulator motor operation.
   1. Remove the power window regulator motor, refer to REMOVAL .

   2. Apply battery voltage to the motor connector according to the table below.
      NOTE:

      Do not apply battery voltage to any terminals except terminals 1 and 2.

      OK

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

2. Check PTC operation:
   NOTE:

   The work must be performed with the power window regulator and door glass installed on the vehicle.

   1. Install the power window regulator motor, refer to INSTALLATION .
   2. Connect an electrical tester DC 400 A probe to the wire harness of terminal 1.

      NOTE:

      Match the arrow mark of the probe with the direction of the current flow.

   3. Fully close the door glass by pressing the power window UP switch. Wait for approximately 60 seconds.
   4. Continue to press the power window UP switch and measure how long it takes for the electrical current to change from a range of 16 to 28 A to approximately 1 A (Inspection of current shut-off).

      Standard

      4 to 90 seconds

   5. 60 seconds after the previous step, press the power window DOWN switch (rear LH side).

      OK

      The rear LH side window goes down.

NG → See step   8 

OK: Go to next step 

1. Disconnect the H8 and K2 connectors.

2. Measure the resistance according to the value(s) in the table below.

   Standard resistance

   Tester Connection	Condition	Specified Condition
   H8-12 (U) - K2-5 (SU)	Always	Below 1 Ω
   H8-13 (D) - K2-2 (SD)	Always	Below 1 Ω
   H8-12 (U) - Body ground	Always	10 kΩ or higher
   H8-13 (D) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK → See step   6
