Restore Peak Performance to Your 3.6L Engine
Is your 2015 Chrysler 300, Dodge Charger, or Challenger suffering from perplexing engine issues? A faulty Engine Control Module (ECM), the central computer of your vehicle, is often the culprit behind problems that mechanics can chase for hours. This direct-fit replacement ECM is the definitive solution for restoring your vehicle’s performance, fuel efficiency, and reliability. It arrives at your door pre-programmed to your specific Vehicle Identification Number (VIN) and mileage, making the installation process a true plug-and-play experience. Forget about expensive towing fees and dealership programming appointments; this module eliminates the extra steps and gets you back on the road quickly.
From the Diagnostic Bay
We had a 2015 Dodge Charger with the 3.6L come in that was a real head-scratcher. The owner had already replaced the crankshaft position sensor twice and the camshaft position sensors, but the car would still intermittently stall at red lights and occasionally refuse to start. The check engine light was on with a slew of communication and sensor circuit codes. After confirming the sensors and wiring were good, we hooked up our scope to the ECM. We found that the 5-volt reference signal from the computer was dropping out randomly, starving the sensors of the power they needed to operate. The root cause wasn’t the sensors at all, but a failing driver inside the original ECM. Installing a properly programmed engine computer solved all the issues instantly, saving the customer from further frustration and unnecessary parts replacement.
Symptoms of a Failing 2015 Chrysler 300 ECM
A failing engine computer can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, your ECM should be a primary suspect. Proper diagnosis is key, but these symptoms are strongly indicative of a module-related problem.
- ✔ Check Engine Light: The check engine light is illuminated, often with codes related to module communication (U-codes) or multiple sensor circuits at once.
- ✔ No-Start or Hard-Start: The engine cranks but refuses to start, or takes an unusually long time to fire up, either hot or cold.
- ✔ Engine Stalling: The vehicle stalls unexpectedly while driving or when coming to a stop.
- ✔ Poor Performance & Fuel Economy: You may notice a significant drop in gas mileage, hesitation during acceleration, or a general lack of power.
- ✔ Rough Idling or Misfires: The engine runs erratically at idle, and you may feel shaking or shuddering.
- ✔ Transmission Issues: The ECM works with the transmission controller, so a faulty module can cause harsh shifting, delayed engagement, or incorrect gear selection.
- ✔ Cooling Fans Not Working: The ECM controls the engine cooling fans. If they don’t turn on, it can lead to overheating.
The Plug-and-Play Advantage
This isn’t just a part; it’s a complete solution. When you order, we flash the module with your vehicle’s unique VIN. This process ensures that the replacement ECM communicates seamlessly with all other modules in your car, including the ignition and security systems. There is no need for any additional programming or key relearn procedures. This simple, direct-swap process makes it an ideal repair for both professional technicians and capable DIY enthusiasts.

Frequently Asked Questions
Is this ECM truly plug-and-play?
Yes. We program the module with the VIN and mileage you provide during checkout. This ensures it integrates perfectly with your vehicle’s existing systems, including the anti-theft security, without any need for a trip to the dealership.
What information do you need from me?
To ensure proper programming, we require your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. Please double-check this information for accuracy before submitting your order.
Where is the ECM located on my 2015 Chrysler 300?
On the 2015 Chrysler 300 and its platform mates (Charger, Challenger), the ECM is typically located in the engine compartment. Look on the passenger side, near the firewall or shock tower. It is a metal box with several large electrical connectors.
Will this fix my check engine light?
If the check engine light and associated codes are caused by a faulty ECM, then yes, this part will resolve the issue. However, it’s crucial to ensure your vehicle has been properly diagnosed, as other failing components can cause similar symptoms.
Do I need to send my old ECM (core) back?
This listing does not require a core return. You can keep your old module, though we always recommend recycling old electronics responsibly.
