Circuit/System Description

WARNING: This page is about a different car, the 2008 Cadillac STS. However, it is still accessible from the selected car via links, so may be relevant.

The electronic brake control module (EBCM) receives invalid information from other modules through the GMLAN serial data bus. The EBCM will set DTC based on this information.
