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 instrument panel cluster (IPC) illuminates the traction off indicator by supplying ground to the lamp. The electronic brake control module (EBCM) sends serial data messages to the IPC to command the indicator ON or OFF.
