TRAC Off Indicator

Instrument Panel Cluster (IPC) illuminates TRAC OFF indicator when following occurs:

• IPC receives a class 2 message from EBCM requesting illumination when Electronic brake control module (EBCM) inhibits traction control system due to a malfunction in traction control system.
• IPC receives a class 2 message from EBCM requesting illumination when Body control module (BCM) detects that traction control switch has been pressed (signal circuit is low). BCM sends a class 2 message to EBCM in order to disable traction control. BCM sends a class 2 message to radio in order to activate an audible warning.
• If brakes begin to overheat, traction control system will turn off and TRAC OFF indicator will illuminate until brake cool down.
