Check Gauges Lamp

The check gauges lamp illuminates when the engine oil pressure is low or the engine coolant temperature is high.

The instrument cluster's check gauges lamp driver, solid state logic, monitors the input signals to the oil pressure gauge and the temperature gauge. When the ignition switch is turned to the RUN or the START position, the check gauges lamp driver grounds the check gauges lamp when either of the input signals exceed the set point. this causes the lamp to illuminate. The lamp is normally illuminated when the ignition switch is turned to the RUN position. The lamp turns oft when the engine is started and the oil pressure increases above the set point. All connections of the check gauges lamp driver are within the I/P Cluster Assembly.
