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 Powertrain Management/Computer and Control System/Vehicle Speed Control for diagnosis of the vehicle speed control system.
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 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 diagnosis of the cruise-on indicator lamp and the instrument cluster circuitry, see Instrument Panel,
Gauges and Warning Indicators/Instrument Panel.
