Malfunction Indicator Lamp: Testing and Inspection
The diagnosis found here addresses an inoperative malfunction indicator (Check Engine) lamp condition. If the lamp comes on and stays on with the
engine running, refer to Powertrain Management/Computers and Control Systems/Testing and Inspection. See: Powertrain Management/Computers and
Control Systems/Testing and Inspection
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 malfunction indicator lamp falls to light during the bulb test (about two seconds after the ignition switch is turned to the On position), replace the
malfunction indicator lamp bulb with a known good unit. If the indicator 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 malfunction indicator lamp
and the instrument cluster circuitry, refer to Instrument Panel/Testing and Inspection. See: Instrument Cluster / Carrier/Testing and Inspection
