OK: GO TO NEXT STEP 

1. Remove the motor.
2. Apply positive (+) battery voltage to the connector terminal 2.
   NOTE:

   • Do not apply positive (+) battery voltage to any terminals, except terminal 2, 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 and 7/10.
4. Check that the motor gear rotates smoothly as follows.
