Circuit Description

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2002 GMC Yukon XL, 2002 GMC Yukon, 2002 Chevrolet Tahoe, 2002 Chevrolet Suburban, and 2002 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The Instrument Panel Cluster (IPC) illuminates the ABS indicator by supplying ground to the lamp. The Electronic Brake Control Module (EBCM) sends class 2 serial data messages to the IPC in order to command the indicator ON or OFF.
