Instrument Cluster

The instrument cluster contains a high-torque type electric speedometer. The electro-mechanical gauges plug individually into socket-type metal connectors in the cluster case.

Electric Speedometer

The electric speedometer drive replaces the mechanical drive for all C/K applications. Integrated circuits control the air core speedometer and stepper motor odometer.

The speedometer and the odometer receive a signal from the vehicle speed sensor (VSS) calibrator module. This signal is generated from the vehicle speed sensor (VSS).
