Is Your 3.6L Pentastar Engine Running Rough?
The Engine Control Module (ECM), also known as the Powertrain Control Module (PCM), is the electronic brain of your 2015 Dodge Challenger, Charger, or Chrysler 300. It meticulously manages everything from fuel injection and ignition timing to transmission shifts and emissions controls. When this critical component begins to fail, it can cause a cascade of frustrating and often mysterious problems. If you’re dealing with persistent check engine lights, poor performance, or stalling, a faulty ECM is a likely culprit. This replacement 2015 Challenger ECM is the definitive solution to restore your vehicle’s factory performance and reliability.
From the Diagnostic Bay
We had a 2015 Charger 3.6L come into the shop with a complaint that was driving the owner crazy. The car would randomly stall at stoplights, but never consistently. It threw a few generic communication codes, but nothing pointed directly to a single sensor. After hours of chasing wires and testing components, we hooked up a scope to the main processor lines on the ECM. We found that under certain thermal conditions, the processor would drop signal momentarily—just long enough to shut the engine down without storing a hard fault code. Swapping in a pre-programmed ECM like this one solved the problem on the first test drive. It’s a reminder that sometimes the most elusive issues trace back to the vehicle’s central computer.
Common Symptoms of a Failing Engine Computer
- ✔ Check Engine Light: The most obvious sign. The light may be on constantly or intermittently, often with codes related to sensors, communication, or processor faults.
- ✔ Engine Stalling or Misfiring: The engine may stall for no apparent reason, either while driving or at idle. You might also experience rough idling or noticeable engine misfires.
- ✔ No-Start Condition: A completely failed ECM can prevent the engine from starting at all. You may have power to the accessories, but the engine won’t crank or fire.
- ✔ Poor Fuel Economy: If the ECM isn’t correctly managing the air-fuel mixture, you’ll see a significant drop in your vehicle’s gas mileage.
- ✔ Erratic Transmission Behavior: The ECM works with the transmission controller. A failing module can cause harsh shifting, failure to shift, or getting stuck in one gear.
- ✔ Performance Issues: Noticeable loss of power, hesitation during acceleration, and an overall sluggish feeling can all be traced back to a faulty engine computer.

Frequently Asked Questions
What information is needed to program this ECM?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. This ensures the ECM is flashed with the correct software and security keys for your specific car, making it a true plug-and-play installation.
Will this module be truly plug and play?
Yes. Because we program the module to your VIN before shipping, it will not require any additional programming or key relearning procedures. Once installed, the vehicle should start and run correctly, with all security systems functioning as they did from the factory.
Where is the ECM located on my 2015 Challenger/Charger/300?
On these 3.6L models, the ECM is typically located in the engine bay, mounted to the side of the shock tower or near the firewall. It is a silver metal box with several large electrical connectors. Always disconnect the battery before attempting to remove or install the module.
Is this a new or a used part?
This is a high-quality, inspected, and tested used OEM component. Each unit is verified to be fully functional before being programmed and shipped, providing OEM reliability at a great value.
What if I install this ECM and my problem doesn’t go away?
While this ECM will solve issues directly caused by a faulty computer, it will not fix other underlying mechanical or electrical problems. If your symptoms persist after installation, we recommend a thorough diagnosis by a qualified technician to check for issues with sensors, wiring, or other vehicle systems.
