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 AIR-BAGS, 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 AIR-BAG DEPLOYMENT AND POSSIBLE
PERSONAL INJURY.
If the check gauges lamp fails to light during the bulb test (about 3 Seconds after the ignition switch is turned to the On position), replace the check
gauges lamp bulb with a known good unit. 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 Panel, Gauges and Warning Indicators/Instrument Panel/
Instrument Cluster for diagnosis of the check gauges lamp and the instrument cluster circuitry.
