Testing
- Turn ignition on. Check other overhead console functions. If other overhead console functions are operating properly, go to next step. If other overhead console functions are not operating properly, replace overhead console. See OVERHEAD CONSOLES - CONCORDE, INTREPID & 300M article.
- Turn ignition off. Connect scan tool to Data Link Connector (DLC). Turn ignition on. Using scan tool, retrieve Powertrain Control Module (PCM) DTCs. If any PCM DTCs exist, see SELF-DIAGNOSTICS - CONCORDE, INTREPID & 300M article in ENGINE PERFORMANCE. If no PCM DTCs exist, go to next step.
- Ensure injector pulse, pinion factor, fuel fill procedure, brake adjustment and tire size are correct. Repair as necessary. If no problems are found, check if any Technical Service Bulletins (TSBs) apply to vehicle. If no TSBs apply, test is complete.
