Circuit Description
WARNING: This page is about a different car, the 2007 Cadillac XLR. However, it is still accessible from the selected car via links, so may be relevant.
The traction control indicator is controlled by the instrument panel cluster (IPC) via serial data messages from the electronic brake control module (EBCM). The EBCM send a serial data message to the IPC to illuminate the traction control indicator when the EBCM has disabled traction control system (TCS) due to a DTC. The traction control indicator will also turn ON during the instrument cluster bulb check. When the ignition switch is turned to ON, the traction control indicator will turn ON for approximately 3 seconds and then turn OFF.
