### Sunroof Motor/Actuator Synchronization

Important: The sunroof actuator is timed at the factory. If there is battery voltage applied to a new sunroof actuator, the pre-timed settings within the sunroof actuator are lost and cannot be reset or used to accommodate proper installation.

Important: There should be no battery voltage applied to a new sunroof actuator until the following conditions are satisfied:

1. The sunroof window is in a full closed position. Refer to Sunroof Track Timing/Synchronization.
2. The power sunroof actuator is installed to the sunroof module.

Install the power sunroof actuator. Refer to Sunroof Motor/Actuator Replacement.
