ABS Warning 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 ABS is monitored by the ABS, or the ABS/TC/stability assist module, which sends the status signal to the instrument cluster over the SCP communication network. The instrument cluster uses this input to determine whether or not there is a fault with the ABS, or the ABS/TC/stability assist system and turns on the ABS warning indicator according to the input.
