  2. Set the door glass in the fully closed position.
  3. When 60 seconds have elapsed after the door glass is fully closed, check how long it takes for the current to change from approximately 16-34 A into 1 A or less when the power window switch is turned UP once again.
    Standard: Approximately 4-90 seconds
  4. When approximately 60 seconds have elapsed after the inspection of the current cut-off, check that the door glass goes down when the power window regulator switch is turned DOWN.
    If the result is not as specified, replace the motor.
