OK : Go to Next Step 

1. Remove the front power window regulator motor assembly (for Driver Side) (See REMOVAL ).
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
