Sunroof / Moonroof Motor: Service and Repair
Sunroof Motor Synchronization
Synchronization will be necessary anytime the sunroof module battery positive voltage circuit is interrupted. The sunroof module will be synchronized
when the controller learns the full vent position.
To synchronize the sunroof:
1. Turn ON the ignition, with the engine OFF.
2. If the sunroof is open (it not, go to next step), press and hold the front portion of the sunroof switch (close) until the sunroof is completely
closed and stopped.
3. Press and hold the front portion of the sunroof switch (close) until the sunroof is in the full vent position and stopped. Once the system reaches
the full vent position the system will become synchronized.
4. Verify that the system operates normally.
