TRAC Off

The IPC illuminates the TRAC OFF indicator when any of the following occur:

• The electronic brake control module (EBCM) inhibits the traction control system due to a malfunction in the traction control system. The IPC receives a class 2 message from the EBCM requesting illumination. The IPC sends a class 2 message to the BCM in order to activate an audible warning.
• The EBCM detects that the traction control switch is pressed. The IPC receives a class 2 message from the EBCM indicating the switch status.
• The IPC receives a class 2 message from the EBCM requesting illumination of the ABS indicator.
• The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 5 seconds.
