Is Your 2002 Chrysler Concorde or Dodge Intrepid Running Rough?
If you’re dealing with frustrating issues like stalling, erratic shifting, a persistent check engine light, or a complete no-start condition, the root cause is often a failing Engine Control Module (ECM). This central computer is the brain of your vehicle’s 3.5L engine, managing everything from fuel injection and ignition timing to transmission control. When it begins to fail, it can create a cascade of problems that are difficult to diagnose and can mimic other component failures. Don’t let a faulty computer keep your car off the road. This direct-replacement engine computer is the reliable, straightforward solution you need.
From the Diagnostic Bay
We had a 2002 Dodge Intrepid ES come into the shop with a bizarre complaint. The owner said it would randomly refuse to shift out of second gear, but only after it was fully warmed up. There were no specific transmission codes, just a generic communication error. We checked the wiring, the transmission fluid, and the solenoids—everything looked fine. On a hunch, we monitored the data stream from the ECM and noticed that sensor voltage readings would start to fluctuate wildly once the engine bay hit operating temperature. The heat was causing internal faults in the original engine computer. We installed a pre-programmed replacement unit, and the problem vanished instantly. It’s a classic case of the ECM being the ghost in the machine.
Symptoms of a Failing 2002 Concorde Engine Computer
- ✔ Check Engine Light is on with various, often inconsistent, trouble codes.
- ✔ Vehicle refuses to start or has difficulty starting.
- ✔ Poor fuel economy and noticeable loss of power.
- ✔ Engine stalling, stuttering, or misfiring while driving.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Issues with other electronic systems, as the ECM communicates with multiple modules.
- ✔ Failure to pass an emissions test.

Frequently Asked Questions
Do I need to have this computer programmed by a dealer?
No. This engine computer comes fully programmed to your vehicle’s specific VIN and mileage. It is a plug-and-play solution, ready for installation upon arrival. No further programming is required.
Where is the ECM located on my 2002 Concorde or Intrepid?
The Electronic Control Module (ECM) is located in the engine compartment on the driver’s side, near the front of the vehicle. It is typically a silver metal box with several large electrical connectors.
Will this fix my transmission shifting problems?
In many Chrysler and Dodge vehicles of this era, the ECM (also known as the PCM or Powertrain Control Module) controls both engine and transmission functions. If your shifting problems are caused by a faulty computer, this part is designed to resolve those issues.
What is the difference between all the compatible part numbers?
The different letters at the end (AA, AB, AC, etc.) typically represent minor hardware or software revisions from the factory over time. Our unit, programmed to the latest stable software, is fully compatible and interchangeable with all the part numbers listed.
Is any special tool required for installation?
Basic hand tools, such as a socket set, are all that is typically needed to remove and replace the module. The most important step is to disconnect the vehicle’s battery before you begin to prevent any electrical damage.
