Spark

Instrument Cluster Gauges Inoperative

The instrument cluster displays the engine coolant temperature, vehicle speed and the engine speed based on the information from the engine control module (ECM). The ECM sends appropriate information via a serial data circuit to the cluster. The cluster displays the engine coolant temperature, the engine speed, the vehicle speed and the distance travelled, either in kilometres or miles, based on the vehicle requirements.
