Speedometer Gauge
WARNING: This page is about a different car, the 2002 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
The vehicle speed signal (VSS) from all four wheels are hardwired directly to the ABS/TC/IVD. The speed status is then sent to the instrument cluster by the ABS/TC/IVD via the SCP communication network.
