Instrument Cluster: Speedometer

WARNING: This page is about a different car, the 2009 Mercury Grand Marquis and 2009 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.

The instrument cluster (IC) receives the vehicle speed sensor (VSS) signal from the PCM over the HS-CAN. The instrument cluster (IC) monitors the VSS input from the PCM module and commands the speedometer with a corresponding movement of the pointer.
