1. Remove the motor (Click here).
   

2. Apply positive (+) battery voltage to connector terminal 2 (B).
   

   NOTICE:

   1. Do not apply positive (+) battery voltage to any terminals, except terminal 2 (B), to avoid damaging the pulse sensor inside the motor.
      
   1. 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 connector terminals 1 (GND), and 7 (DOWN) or 10 (UP).
   

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

   OK:
