Sunroof Motor/Actuator Synchronization
WARNING: This page is about a different car, the 2006 GMC Sierra and 2006 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
The sunroof control module uses position sensor inputs to establish soft stop locations for the sunroof panel several millimeters ahead of it's physical limits. After replacing sunroof system components which may effect the position of the glass panel to the seal in the closed position, the soft stop locations must be reset. Perform the following steps after the repairs are completed.
- Close the sunroof to the current soft stop location.
- Press and hold the sunroof switch in the close position.
- After 2 seconds the sunroof panel will bump to the hard stop.
- Continue holding the sunroof switch in the close position for 3 full seconds after the sunroof panel has hit the hard stop.
- Press and hold the sunroof switch in the open position until the sunroof panel stops in the full open position.
