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 AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.
FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG 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, see Instrument Cluster in the Diagnosis and Testing for further diagnosis of the check gauges lamp and the instrument
cluster circuitry.
