Odometer: Testing and Inspection
Odometer and Trip Odometer
If the problem being diagnosed is related to odometer and/or trip odometer accuracy, be certain to confirm that the problem is with the display and not
with an incorrect speedometer pinion gear, axle ratio, or tire size.
WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIRBAG SYSTEMS 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 vehicle speed sensor and circuit, the Chrysler Collision Detection (CCD) data bus, the Body Control Module (BCM) and/or the
Powertrain Control Module (PCM) should be performed with a DRB scan tool. For further diagnosis of the odometer and/or trip odometer and the
instrument cluster circuitry, see Instrument Panel, Gauges and Warning Indicators/Instrument Panel/Instrument Cluster.
