Is Your 2015 Dodge or Chrysler Running Rough?
If your 2015 Dodge Charger, Challenger, or Chrysler 300 with the 3.6L engine is experiencing frustrating issues like stalling, poor fuel economy, a persistent Check Engine Light, or even a no-start condition, the root cause is often a failing Engine Control Module (ECM). The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it begins to fail, it can create a cascade of problems that are often misdiagnosed, leading to costly and unnecessary repairs of other components.
From the Diagnostic Bay
We had a 2015 Charger 3.6L come into the shop with a classic complaint: intermittent stalling at red lights and a check engine light that kept pointing to a random misfire (P0300). The owner had already replaced the spark plugs, ignition coils, and even a camshaft position sensor based on other advice. The problem persisted. After hooking up our diagnostic scanner and monitoring live data, we noticed erratic fuel trim and injector pulse width readings. Instead of chasing more sensors, we inspected the ECM. A quick test confirmed internal circuit failure. We installed a correctly programmed replacement module, and the Charger ran perfectly. This is a common scenario where chasing symptoms instead of the source leads to frustration and wasted money. A faulty ECM can mimic many other problems.
Symptoms of a Failing 2015 Charger ECM
- ✔ Check Engine Light: The light is on, and you may have codes related to misfires, sensor circuits, or internal module failure.
- ✔ Engine Stalling or Misfiring: The engine may stall unexpectedly, run rough, or hesitate during acceleration.
- ✔ No-Start Condition: The engine cranks but refuses to start, often due to a lack of spark or fuel delivery command from the ECM.
- ✔ Poor Fuel Economy: A failing module can’t efficiently manage the engine, leading to a noticeable drop in MPG.
- ✔ Inconsistent Performance: You might experience a loss of power, erratic shifting from the automatic transmission, or other strange drivability issues.
- ✔ Communication Errors: Your mechanic’s scan tool may be unable to communicate with the engine computer, a clear sign of module failure.

Frequently Asked Questions
Do I need to do any programming after I install this ECM?
No. This module comes fully programmed to your vehicle’s VIN. The process is 100% Plug-and-Play. Simply install the unit, and your vehicle will start and run correctly without any additional dealership visits.
How do I provide my VIN?
You will be prompted to provide your vehicle’s VIN during the checkout process. This is a critical step to ensure we program the module correctly for your specific car.
Is this a difficult part to install?
For someone with basic mechanical skills, the installation is straightforward. It typically involves disconnecting the battery, unplugging the electrical connectors from the old ECM, unbolting it, and then reversing the process with the new unit. We always recommend consulting a repair manual for the exact location and procedure.
Will this fix my check engine light?
If the check engine light and associated codes are caused by a faulty ECM, this replacement part will solve the issue. It’s important to ensure that the problem has been correctly diagnosed and that there are no other underlying issues with sensors or wiring.
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. PCM (Powertrain Control Module) is a more inclusive term for a module that controls both the engine and the transmission. For this vehicle, this module serves as the brain for the entire powertrain.
