Trac Off

The IPC illuminates the TRAC OFF indicator when:
^ The Electronic Brake Control Module (EBCM) inhibits the traction control system. The IPC receives a class 2 message from the EBCM requesting illumination.
^ The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.

The IPC sends a class 2 message to the radio in order to activate an audible warning.
