Is Your 2015 Chrysler, Dodge, or 300 Acting Up? The ECM Might Be the Culprit.
There’s nothing more frustrating than a vehicle that won’t perform as it should. If your 2015 Chrysler 300, Dodge Challenger, or Dodge Charger with the 3.6L engine is experiencing erratic behavior like stalling, poor acceleration, or a persistent Check Engine Light, the problem may lie deep within its electronic core: the Engine Control Module (ECM). The ECM is the central computer, the brain of your engine’s operations, responsible for managing everything from fuel injection and ignition timing to emissions control and transmission shifting. When it fails, it can cause a cascade of confusing and debilitating symptoms.
From the Diagnostic Bay
We had a 2015 Charger 3.6L come in on a tow truck. The owner was at his wit’s end. The car would crank but wouldn’t start, and when it occasionally did, it ran horribly for a few seconds before stalling. He had already replaced the spark plugs, a coil pack, and even the fuel pump based on advice from forums. We connected our diagnostic scanner and found a U0100 ‘Lost Communication with ECM’ code. After verifying the power and ground circuits to the module were intact, we knew we were dealing with an internal failure. A replacement 2015 300 ECM, programmed to the vehicle’s VIN, had it running perfectly in under an hour. It’s a classic case where chasing symptoms can be costly, while correctly diagnosing the root cause provides a swift, effective solution.
Common Symptoms of a Failing 2015 300 ECM
- ✔ Check Engine Light: The most common indicator, often with codes related to module communication or specific sensor circuits that are actually functioning correctly.
- ✔ Engine Stalling or Misfiring: The engine may stall unexpectedly while driving or at idle. You might also experience rough running or misfires as the ECM fails to properly control spark and fuel.
- ✔ No-Start Condition: The engine will crank over but will not fire up because the ECM is not commanding the fuel injectors or ignition coils to operate.
- ✔ Poor Performance and Fuel Economy: A failing module can lead to incorrect air/fuel mixtures and timing, resulting in a noticeable drop in power, acceleration, and miles per gallon.
- ✔ Transmission Shifting Issues: The ECM works in tandem with the transmission controller. A faulty ECM can cause harsh shifting, a failure to shift, or the vehicle getting stuck in ‘limp mode’.
- ✔ Intermittent Problems: Issues may appear randomly, often worsening as the engine warms up, which can make diagnosis extremely difficult.

Frequently Asked Questions
Is this ECM really plug and play?
Yes, absolutely. We program the module with your car’s specific VIN and mileage before shipping it. Once you receive it, you can install it, and it will work immediately without any need for a trip to the dealer or a specialized scan tool for programming.
What information do you need from me?
After you place your order, we will need your vehicle’s 17-digit VIN (Vehicle Identification Number). This is crucial for us to load the correct software and vehicle-specific data onto the module. You can typically find the VIN on your dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
How do I know if my ECM is the problem?
While the symptoms listed above are strong indicators, a definitive diagnosis is always recommended. This usually involves a professional mechanic checking for specific diagnostic trouble codes (DTCs), especially communication codes (U-codes), and verifying power and ground signals at the ECM connector. Replacing an ECM without a proper diagnosis can be a costly mistake.
Where is the ECM located on my vehicle?
On the 2015 Chrysler 300, Charger, and Challenger models, the ECM is typically located in the engine bay. It is a metal box with several large electrical connectors. Always disconnect the vehicle’s battery before attempting to unplug or remove the old module.
Does this part fit other vehicles besides the 2015 Chrysler 300?
Yes. This specific module and its programming are also compatible with the 2015 Dodge Challenger and 2015 Dodge Charger, as long as they are equipped with the 3.6L V6 engine.
