Section 9 (Analog Instrument Panels): Operation: Gauges

WARNING: This page is about a different car, the 2000 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

The IPC controls gauge functions with signals received on the serial data line or by a dedicated circuit from another system. The gauges may be toggled between English and Metric units by pressing the E/M button. Each gauge contains damping fluid to ensure smooth and steady operation of the needle.

The IPC receives a 4000 pulse-per mile Vehicle Speed Sensor (VSS) input over a dedicated circuit from the PCM. Engine RPM input information sent from PCM on a dedicated circuit to the IPC. The IPC also receives engine RPM data on the serial data line. The PCM is responsible for processing and sending VSS and engine RPM data to the IPC.

IPC receives fuel level, oil pressure and coolant temperature data from the PCM on the serial data line. The IPC receives vehicle voltage data through ignition 1 circuit which is directly connected to the IPC.
