Fuel Gauge: Testing and Inspection
If the problem being diagnosed is related to fuel gauge accuracy, be certain to confirm that the problem is with the gauge or sending unit and not with the
fuel tank. Inspect the fuel tank for signs of damage or distortion that could affect the sending unit performance before you proceed with fuel gauge
diagnosis.
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.
Diagnosis of the fuel gauge sending unit and circuit, the Chrysler Collision Detection (CCD) data bus, and/or the Powertrain Control Module (PCM)
should be performed with a DRB scan tool. For diagnosis of the fuel gauge and the instrument cluster circuitry, see Instrument Panel, Gauges and
Warning Indicators/Instrument Panel.
