Check Gauges Lamp: Testing and Inspection
The diagnosis found here addresses an inoperative check gauges lamp condition. If the check gauges lamp stays on with the ignition switch in the On
position, or comes on while driving with no unusual gauge readings evident, diagnosis of the Powertrain Control Module (PCM) and the Chrysler
Collision Detection (CCD) data bus should be performed with a DRB scan tool.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIRBAGS BEFORE ATTEMPTING ANY STEERING WHEEL,
STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER
PRECAUTIONS COULD RESULT IN ACCIDENTAL AIR BAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
If the coolant temperature gauge, oil pressure gauge, or voltmeter are giving an indication that should trigger the check gauges lamp, but the check
gauges lamp still fails to operate, refer to Instrument Panel/Testing and Inspection for further diagnosis of the check gauges lamp and the instrument
cluster circuitry. See: Instrument Cluster / Carrier/Testing and Inspection
