Check Gauges Indicator

The check gauges indicator is a LED display located in the instrument cluster. The check gauges indicator turns ON for 3 seconds when the ignition switch is turned to the RUN position. The instrument cluster is constantly monitoring the engine coolant temperature and engine oil pressure when the engine is running. The engine coolant temperature information is sent to the instrument cluster over the Class 2 serial data line by the VCM/PCM. The engine oil pressure information is sent to the instrument cluster from a designated circuit connected to the oil pressure sensor. The instrument cluster will turn the CHECK GAUGES indicator ON if the engine coolant temperature gets too high or if the engine oil pressure gets too low while the engine is running.
