Is Your 2015 Dodge or Chrysler Running Rough?
If your 2015 Dodge Challenger, Charger, or Chrysler 300 with the 3.6L Pentastar engine is experiencing frustrating issues like stalling, poor fuel economy, a persistent check engine light, or a complete no-start condition, the root cause is often a failing Engine Control Module (ECM). The ECM is the brain of your vehicle’s engine, 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 difficult to diagnose and can leave you stranded. Don’t let a faulty computer dictate your driving experience. This direct-fit replacement ECM is the reliable, straightforward solution you need to restore your vehicle’s performance and peace of mind.
From the Diagnostic Bay
We had a 2015 Dodge Charger 3.6L come into the shop with a complaint that was driving the owner crazy. The car would run perfectly for days, then suddenly stall at a stoplight and refuse to restart for 10-15 minutes. There were no consistent trouble codes, just a few random communication errors that would come and go. We checked the fuel pump, sensors, and wiring, but everything tested fine. After hours of diagnostics, we noticed that the failures only happened after the engine was fully warmed up. On a hunch, we carefully heated the original ECM with a heat gun, and sure enough, the engine stalled and wouldn’t restart. The thermal stress was causing an internal failure in the module. We replaced it with one of our pre-programmed units, and the Charger has been running flawlessly ever since. These intermittent issues are a classic sign of a failing ECM.
Symptoms of a Failing 2015 Challenger Engine Computer
A failing ECM can manifest in various ways. If you’re noticing any of the following symptoms, it’s a strong indication that your engine computer may need replacement:
- ✔ Check Engine Light: The check engine light is illuminated, often with codes related to sensors, communication errors (U-codes), or processor faults.
- ✔ No-Start Condition: The engine cranks but will not start, or it won’t crank at all, despite having a good battery and starter.
- ✔ Poor Engine Performance: You may experience rough idling, hesitation during acceleration, stalling, or a noticeable loss of power.
- ✔ Reduced Fuel Economy: A faulty ECM can’t properly manage the air-fuel mixture, leading to a significant drop in your vehicle’s MPG.
- ✔ Transmission Issues: The ECM works with the TCM, so a failure can cause harsh shifting, getting stuck in gear, or other erratic transmission behavior.
- ✔ Intermittent Problems: Issues that appear and disappear, often related to engine temperature, are a common sign of an internal ECM failure.
The Plug-and-Play Solution
The biggest hurdle in replacing a modern vehicle’s computer is the programming.

Frequently Asked Questions
Is this engine computer really Plug and Play?
Yes, absolutely. We program the module using your vehicle’s VIN before we ship it. This programming includes all the necessary security and immobilizer data, so it will work immediately upon installation without any need for a trip to the dealership or a specialized scan tool.
What information do you need from me to program it?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) to ensure the programming is a perfect match for your car’s specific configuration. Please provide your VIN during the checkout process to avoid any delays.
How can I be sure my old ECM is the problem?
While the symptoms listed above are strong indicators, a definitive diagnosis is always best. A professional mechanic can check for communication with the ECM and rule out other potential causes like faulty wiring or sensors. Common diagnostic trouble codes pointing to a bad ECM include P0600-P0606 or U-codes indicating a loss of communication.
Where is the ECM located on my 2015 Challenger, Charger, or 300?
On these 3.6L models, the ECM is typically located in the engine bay. You can usually find it mounted on the driver’s side, near the shock tower or behind the headlight assembly. It is a silver metal box with several large electrical connectors.
Will this fix my check engine light?
If the check engine light is on due to an internal fault within the original ECM, then yes, this replacement part will resolve the issue and the light. However, if the light is on because of a separate faulty sensor or a mechanical problem, that issue will still need to be addressed.
