Instrument Cluster Gauges: Speedometer
WARNING: This page is about a different car, the 2006 Mercury Montego, 2006 Ford Freestyle, and 2006 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.
The instrument cluster receives the vehicle speed sensor (VSS) signal from the ABS module over the communication network, and monitors the VSS input and commands the speedometer pointer.
