the initial position of the power window motor can be reset by performing the following procedure. (For details,
See S-12 DRIVER-SIDE POWER WINDOW MOTOR RESETTING.)
• When the door glass is raised, the slider pin stops at the end of the scroll groove, thus activating the clutch to
rotate gear A only and the plate remains stopped.
• As a result, the position of the limit switch to the output axis is displaced and the switch mechanically
memorizes the fully closed position.
