Is Your Dodge Charger or Chrysler 300 Running Rough?
If you’re dealing with frustrating issues like stalling, no-start conditions, erratic behavior, or a persistent check engine light that just won’t go away, a failing Engine Control Module (ECM) could be the culprit. The ECM is the brain of your vehicle’s engine, responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it starts to fail, it can cause a cascade of problems that are often difficult to diagnose, leaving you stranded and facing a costly trip to the dealership.
This direct replacement Engine Control Module, part number 5150246AD, is the definitive solution for your 2008-2010 Dodge Charger, Chrysler 300, Dodge Magnum, or 2009 Dodge Challenger. We eliminate the guesswork and the expensive programming fees by delivering a unit that is pre-programmed specifically to your vehicle’s Vehicle Identification Number (VIN) and current mileage. This means the module arrives at your door ready for a true plug-and-play installation.
From the Diagnostic Bay
We had a 2009 Chrysler 300 with the 3.5L V6 come into the shop with a complaint of harsh, unpredictable shifting and occasional stalling at stoplights. The owner had already replaced the transmission speed sensors and fluid with no improvement. Scans showed intermittent communication loss with the TCM (Transmission Control Module), but all wiring checked out. After hours of chasing electrical gremlins, we focused on the ECM. On a hunch, we connected a known-good ECM, and the problems vanished instantly. The original ECM had internal circuit failure that was corrupting the CAN bus network, making the transmission act erratically. It’s a classic case where the root cause isn’t where the symptoms appear, and this pre-programmed module would have saved the owner hundreds in diagnostic time.
Symptoms of a Failing Engine Computer
- ✔ Check Engine Light is on with various communication or sensor codes (e.g., U-codes, P0600-P0606).
- ✔ Engine misfires, runs rough, or has poor acceleration.
- ✔ Vehicle stalls intermittently or fails to start at all.
- ✔ Noticeable decrease in fuel economy.
- ✔ Automatic transmission shifts harshly, erratically, or not at all.
- ✔ Cooling fans run constantly or not at all, leading to overheating.
- ✔ Other electronic modules in the vehicle behave unpredictably.

Frequently Asked Questions
Will this computer be truly plug-and-play?
Yes. We program the unit with the VIN you provide during checkout. This process flashes the module with your vehicle’s specific software and immobilizer information, making it ready for installation without any additional programming required.
Where is the ECM located on my vehicle?
On the 2008-2010 Dodge Charger, Chrysler 300, and Dodge Magnum, the Electronic Control Module is located in the engine compartment on the driver’s side (LH side), near the front.
Do I need to send my old computer (core) back?
This listing does not require a core return. You can keep your old module. However, please be sure to recycle it properly according to your local regulations for electronic waste.
What is the difference between an ECM, ECU, and PCM?
The terms are often used interchangeably. ECM (Engine Control Module) and ECU (Engine Control Unit) typically refer to the same part. A PCM (Powertrain Control Module) is a more integrated unit that controls both the engine and the transmission. For your vehicle, this module functions as the primary engine controller.
How do I find my car’s VIN?
You can find your 17-digit Vehicle Identification Number (VIN) on your vehicle’s registration, insurance card, or on the driver’s side dashboard visible through the windshield.
