Circuit Description
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Oldsmobile Bravada, 2004 GMC Envoy XUV, 2004 GMC Envoy XL, 2004 GMC Envoy, and 2004 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
The power roof open switch, power roof close switch, cargo area exit switch, end gate window switch up, end gate window switch down and end gate window switch express down signal circuits provide inputs to the power roof module when the appropriate switch is activated. These inputs allow the roof module to detect a switch request. The roof module provides both power and ground for these switches. If the roof module detects a short to ground on any of these circuits, a DTC is set.
