B0516 CADILLAC Meaning
The Instrument Panel Cluster (IPC) receives vehicle speed information from the Powertrain Control Module (PCM
). IPC receives a 4000 pulse-per mile Vehicle Speed Sensor (VSS) input over a dedicated circuit from PCM
is responsible for processing and sending VSS data to IPC. IPC monitors VSS output information sent from PCM
for an out of range condition.
