Initialization Procedure

WARNING: This page is about a different car, the 2020 GMC Terrain and 2020 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.

"Initialization" refers to the sunroof system learning the reference location of the hard stop. Initialization is done in the following scenarios:

First Time System is Powered - Initialization has not been executed yet
Sunroof/Sunshade lost calibration or false reversal
Motor assembly has been removed or replaced
If the glass is adjusted after Sunroof / Sunshade initialization has already been completed

Until the motor assembly has been initialized, the express open and close switch inputs and manual open inputs are disregarded. During the process of initialization, anti-pinch detection is not active.
