   *b	Counterclockwise
   *c	Clockwise

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(GND) and 7 (DOWN) / 10(UP).
4. Check that the motor gear rotates smoothly as follows.

   OK

   Measurement Condition	Specified Condition
   Battery positive (+) → 2 (B) Battery negative (-) → (-): 1(GND) (3 sec. or more) → 1(GND) and 10(UP) (within 1 sec.) → 1(GND) (within 1 sec.) → 1(GND) and 10(UP)	Motor gear rotates clockwise
   Battery positive (+) → 2 (B) Battery negative (-): 1(GND) (3 sec. or more) → 1(GND) and 7(DOWN) (within 1 sec.) → 1(GND) (within 1 sec.) → 1(GND) and 7(DOWN)	Motor gear rotates counterclockwise

5. Reinstall the front power window regulator motor assembly LH.

Result: 

OK
