Traction Control Indication
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 traction control is communicated to the instrument cluster from the ABS/TC/stability assist module via the SCP communication network. When the traction control system is active, the ABS/TC/stability assist module sends a command to the instrument cluster to illuminate the traction control indicator.
