Diagnostic Aids

WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.

The sunroof glass is controlled by an integrated motor/controller containing the motor, electronics, and position sensors. If the motor and sunroof mechanism get out of sync the sunroof may operate erratically. To re-synchronize the motor and sunroof mechanism, perform the Sunroof Motor/Actuator Initialization/Teach Process .
The sunroof control module provides obstacle/blockage detection. If the Sunroof Motor/Actuator Initialization/Teach Process is not carried out completely, the sunroof may stop and reverse slightly when it gets to the location where it needs to push down the windscreen. Make sure to complete the process.
