Instrument Panel Cluster (IPC) Description and Operation: Speedometer

WARNING: This page is about a different car, the 2003 Pontiac Montana, 2003 Oldsmobile Silhouette, and 2003 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.

The IPC displays vehicle speed as determined by the PCM. The IPC receives a class 2 message from the PCM. The Vehicle Speed Sensor (VSS) discrete signal is pulled up to ignition voltage in the PCM. The IPC uses the VSS data received from the PCM and a software program to determine the proper vehicle speed to display.
