TRAC Active
WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.
The status of the advance traction control system is communicated to the instrument cluster from the ABS/TC/stability assist module. When the advance traction control system is switched OFF, the instrument cluster illuminates the advance traction indicator and sends a message to the ABS module.
