Restore Peak Performance to Your Chrysler 3.5L
Is your 2002 Chrysler Concorde, Intrepid, or 300M suffering from perplexing engine issues? A faulty Engine Control Module (ECM) is often the culprit behind problems like erratic idling, poor fuel economy, stalling, or a dreaded no-start condition. The ECM acts as the central brain for your vehicle’s engine, managing critical functions like fuel delivery, spark timing, and emissions control. When it fails, the entire system’s performance and reliability are compromised. This replacement 2002 Concorde engine computer is the definitive solution to get your vehicle running smoothly and dependably once again.
From the Diagnostic Bay
We had a 2002 Dodge Intrepid R/T come into the shop with a frustrating intermittent stalling problem. The owner had already replaced the crank and cam sensors, but the car would still die randomly at stoplights. After hooking up the scanner and monitoring live data, we noticed the 5-volt reference signal would occasionally drop out for a split second, just before the stall. This pointed directly to an internal fault in the ECM. We installed one of these pre-programmed units, and the car ran perfectly. It saved the customer from endless guesswork and the high cost of a dealership repair.
Why Choose a Pre-Programmed ECM?
Replacing an ECM isn’t just a matter of swapping parts. A new module must be programmed with your vehicle’s specific Vehicle Identification Number (VIN) and current mileage to communicate correctly with the other onboard systems. Our service eliminates this complex and costly step. We flash the module before it ships, making it a true plug-and-play solution. Simply disconnect the battery, swap the old module with this one, reconnect the battery, and you’re ready to drive. No trips to the dealer, no special tools, and no additional programming fees.

How can I be sure my original ECM has failed?
While the symptoms listed above are strong indicators, a definitive diagnosis is best. This involves checking for consistent power and ground at the ECM connector and ensuring other components like sensors and wiring are functioning correctly. If all other potential causes have been ruled out, the ECM is the likely culprit.
