Emissions Maintenance Light: Testing and Inspection
The diagnosis found here addresses an inoperative Service Reminder (Maintenance Required) Indicator (SRI) lamp condition. If the required emission
control systems maintenance has been completed, use a DRB scan tool and the proper Diagnostic Procedures to reset the Powertrain Control Module
(PCM) lamp mileage counter.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, 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 AIRBAG DEPLOYMENT AND POSSIBLE
PERSONAL INJURY.
If the SRI lamp fails to light during the bulb test (about two seconds after the ignition switch is turned to the On position), diagnosis of the Powertrain
Control Module (PCM) and the Chrysler Collision Detection (CCD) data bus should be performed with a DRB scan tool as described in the proper
Diagnostic Procedures. For further diagnosis of the SRI lamp and the instrument cluster circuitry, see Instrument Cluster in the Diagnosis and Testing.
