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 radio in order to activate an audible warning.
^ The IPM detects that the traction control switch is pressed. The IPC receives a class 2 message from the IPM requesting illumination.
^ The IPC receives a class 2 message from the EBCM requesting illumination of the ABS indicator.
^ The IPC detects a loss of class 2 communications with the EBCM, and the discrete back-up ABS signal circuit is high.
^ The IPC performs the displays test at the start of each ignition cycle. The indicator is illuminated for approximately 5 seconds.
