Service Tool Commanded Open
WARNING: This page is about a different car, the 2017 GMC Acadia. However, it is still accessible from the selected car via links, so may be relevant.
When a service tool commands the sunroof open, it results in the Sunroof going to half way point mentioned above or to the fully open depending on the calibration. If the half way point is calibrated on, this position is as far as the sunroof can be opened with the service tool. To go beyond this point a switch activation must be used.
