Instrument Panel, Gauges and Warning Indicators: Application and ID

The Check Gages Lamp lights when either the engine oil pressure is low or the engine coolant temperature is high. The Instrument Cluster's Check Gages Lamp Driver solid state logic monitors the input signals to the Oil Gage and the TEMP Gage. With the Ignition Switch in "RUN" or "START," the Check Gages Lamp Driver grounds the Check Gages lamp when either of the input signals exceeds its setpoint. This causes the lamp to light. The lamp is normally illuminated when the Ignition Switch is placed in "RUN". It extinguishes when the engine is started and oil pressure increases above setpoint.
