Circuit/System Description

The electronic brake control module (EBCM) sends a serial data message to the instrument panel cluster (IPC) to illuminate the Traction Control indicator when the EBCM has disabled the 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.
