      *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.
