   Standard resistance

   Tester Connection	Condition	Specified Condition
   Q13-20 (U) - M14-10 (UP1)	Always	Below 1 Ω
   Q13-16 (D) - M14-7 (DWN1)	Always	Below 1 Ω
   Q13-20 (U) - Body ground	Always	10 kΩ or higher
   Q13-16 (D) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Remove the front power window regulator motor assembly (for Driver Side). Refer to REMOVAL - Step 20 .
2. Apply positive (+) battery voltage to the connector terminal 2 (B).
   NOTE:

   • Do not apply positive (+) battery voltage to any terminals, except terminal 2 (B), to avoid damaging the pulse sensor inside the motor.
   • Reset the power window regulator motor (initialize the pulse sensor) after installing the power window regulator motor and regulator assembly onto the door.
3. Apply negative (-) battery voltage to the connector terminals 1 (E) and 7 (DWN1)/10 (UP1).

4. Check that the motor gear rotates smoothly as follows.

   OK

   Measurement Condition	Specified Condition
   Battery positive (+) → 2 (B) Battery negative (-): 1 (E) (3 seconds or more) → 1 (E) and 10 (UP1) (within 1 second) → 1 (E) (within 1 second) → 1 (E) and 10 (UP1)	Motor gear rotates clockwise (UP)
   Battery positive (+) → 2 (B) Battery negative (-): 1 (E) (3 seconds or more) → 1 (E) and 7 (DWN1) (within 1 second) → 1 (E) (within 1 second) → 1 (E) and 7 (DWN1)	Motor gear rotates counterclockwise (DOWN)
