Cruise Control Indicator Lamp: Testing and Inspection
The diagnosis found here addresses an inoperative cruise-on indicator lamp condition. If the problem being diagnosed is an inaccurate cruise-on
indicator lamp, refer to Cruise Control for diagnosis of the vehicle speed control system.
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 AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
If the cruise-on indicator lamp fails to light when the vehicle speed control is turned on, replace the cruise-on indicator lamp bulb with a known good
unit. If the cruise-on lamp still fails to operate, diagnosis of the Powertrain Control Module (PCM) and the Chrysler Collision Detection (CCD) data bus
should be performed with a DRB scan tool. For further diagnosis of the cruise-on indicator lamp and the instrument cluster circuitry, see Instrument
Cluster.
