Is Your 2015 Dodge Charger, Challenger, or Chrysler 300 Running Rough?
The heart of your vehicle’s performance and reliability is the Engine Control Module (ECM), often called the engine computer. For the 2015 Dodge Charger, Challenger, and Chrysler 300 equipped with the robust 3.6L Pentastar engine, the ECM is the central command center. It meticulously manages everything from fuel injection and ignition timing to transmission shifting and emissions control. When this critical component begins to fail, it can cause a cascade of confusing and frustrating problems, often leaving you stranded or dealing with a vehicle that’s unpredictable and unsafe to drive. If you’re experiencing erratic engine behavior, poor fuel economy, or a persistent Check Engine Light, a failing ECM is a likely culprit.
A customer brought in their 2015 Dodge Charger 3.6L with a complaint that stumped two other shops. The car would randomly stall at red lights and occasionally refuse to start, but there were no consistent trouble codes—just a random assortment of U-codes (communication errors) and an intermittent P0606 (Internal Control Module Processor Error). We checked all the basics: battery, alternator, grounds, and wiring harnesses. Everything looked perfect. On a hunch, we monitored the live data stream from the ECM and noticed that the 5-volt reference signal to several key sensors would momentarily drop out right before a stall. This pointed directly to an internal failure within the ECM itself. After replacing it with a correctly programmed unit like this one, the voltage stabilized, the random codes vanished, and the stalling issue was completely resolved. It’s a classic example of how a faulty ECM can create phantom problems that are nearly impossible to trace without pinpointing the source.
Symptoms of a Failing 2015 Charger Engine Computer
A failing engine computer can manifest in numerous ways. If your 3.6L Mopar is exhibiting any of the following issues, it’s time to consider a replacement ECM. Ignoring these signs can lead to further damage to other components, including your catalytic converter or transmission.
- ✔ Check Engine Light: The most common indicator. You may see codes related to internal processor failure (e.g., P0600-P0606), sensor circuits, or communication errors.
- ✔ No-Start or Hard Starting: The engine cranks but refuses to start, or takes an unusually long time to fire up. This can be due to the ECM not commanding the fuel pump or ignition coils correctly.
- ✔ Engine Stalling or Misfiring: The vehicle may stall unexpectedly while driving or at idle. You might also feel random shaking or hesitation, which indicates a misfire that the ECM is failing to manage.
- ✔ Poor Performance and Fuel Economy: A noticeable drop in acceleration and a significant increase in fuel consumption are strong signs that the ECM is not calculating the air-fuel mixture correctly.
- ✔ Erratic Transmission Shifting: The ECM works in tandem with the Transmission Control Module (TCM). A faulty ECM can send incorrect data, leading to harsh shifts, delayed engagement, or the transmission getting stuck in one gear (limp mode).
- ✔ Cooling Fans Not Working: The ECM controls the engine cooling fans. If they fail to turn on, it can lead to overheating, a critical issue for any engine.
- ✔ Intermittent Electrical Issues: Because the ECM communicates with nearly every other module on the vehicle, its failure can cause bizarre, unrelated electrical gremlins to appear.
The Plug & Play Solution You Need
Replacing an ECM isn’t as simple as swapping out a battery. Modern vehicle security systems, known as immobilizers, require the new ECM to be programmed to your specific Vehicle Identification Number (VIN). Without this programming, the vehicle will not start. This typically means a costly trip to the dealership for programming fees and vehicle towing. Our solution eliminates that hassle entirely.
This engine computer for your 2015 Dodge Charger, Challenger, or 300 arrives at your door fully programmed to your vehicle’s VIN and mileage. It is a true Plug & Play installation. Simply disconnect the battery, swap the old module with this one, reconnect the battery, and start your car. There are no additional programming steps, no special tools required, and no expensive dealer visits. You can restore your vehicle’s proper function right in your own driveway.

Frequently Asked Questions
Do I need to take my car to the dealer after installing this?
Absolutely not. This 2015 Charger Engine Computer comes pre-programmed to your vehicle’s specific VIN. The security information is already loaded, making it a true plug-and-play part. Just install it and you’re ready to go.
What information do you need from me to program the computer?
During the checkout process, we will ask for your vehicle’s 17-digit VIN and the current mileage. This information is crucial for us to program the module correctly so it communicates perfectly with the other systems in your car.
Is this a difficult part to install myself?
For most DIY mechanics, the installation is straightforward. The ECM is typically located in the engine bay and is held in place by a few bolts and has several electrical connectors. The most important step is to disconnect the vehicle’s battery before you begin. The entire process can usually be completed in under an hour with basic hand tools.
Will this fix my specific problem?
While this part resolves the vast majority of issues caused by a faulty ECM, it’s essential to have your vehicle properly diagnosed. The symptoms of a bad ECM can sometimes overlap with other issues, like a faulty sensor or wiring problem. We recommend confirming the diagnosis before ordering.
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) refer to the same computer that manages engine functions. PCM (Powertrain Control Module) is a term for a more integrated unit that controls both the engine and the transmission. For this specific vehicle, it is most commonly referred to as the ECM.
