Is Your 2015 Dodge or Chrysler Acting Up? The Engine Computer Might Be the Culprit.
There’s nothing more frustrating than a vehicle that’s unreliable. If your 2015 Dodge Challenger, Charger, or Chrysler 300 with the 3.6L Pentastar engine is experiencing baffling issues like stalling, poor fuel economy, or an illuminated Check Engine Light, the problem may lie deep within its electronic core: the Engine Control Module (ECM). This component is the central brain of your vehicle’s powertrain, responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it starts to fail, it can cause a cascade of problems that are often difficult to diagnose.
From the Diagnostic Bay
We recently had a 2015 Dodge Charger 3.6L come into the shop with a very peculiar problem. The owner complained of intermittent stalling at stop lights and a random misfire that would come and go. The check engine light would flash occasionally but never store a consistent trouble code. We checked the usual suspects – spark plugs, coils, fuel pressure, and wiring grounds – but everything seemed fine. The intermittent nature of the fault pointed us towards an electronic issue. We suspected the ECM was failing internally. Instead of a costly and time-consuming trip to the dealer, we installed one of our pre-programmed units. The result? The stalling and misfires vanished immediately. It was a classic case of a failing 2015 Challenger engine computer causing ghost-like problems that a simple part replacement solved perfectly.
Common Symptoms of a Failing 3.6L ECM
- âś” Persistent Check Engine Light: The most obvious sign. You may see codes related to internal processor failure (like P0606) or communication errors (U0100).
- âś” Engine Stalling or Misfiring: The engine may stall for no reason, run rough, or hesitate during acceleration as the ECM fails to correctly manage fuel and spark.
- âś” No-Start Condition: The vehicle may crank but refuse to start because the ECM isn’t activating the fuel pump or ignition system.
- âś” Poor Performance and Fuel Economy: An inefficiently running engine, controlled by a faulty ECM, will often lead to a noticeable drop in power and an increase in fuel consumption.
- âś” Erratic Transmission Behavior: The ECM works closely with the transmission controller. A failing module can cause harsh shifting, delayed engagement, or incorrect gear selection.
- âś” Communication Failure: In some cases, a diagnostic scan tool may be unable to communicate with the ECM, making diagnosis impossible.

Frequently Asked Questions
What information do you need to program the computer?
During the checkout process, we require your vehicle’s 17-digit VIN (Vehicle Identification Number) and the current mileage. This information is critical to ensure the module is programmed correctly and functions as a true plug-and-play unit.
Is this really a ‘plug-and-play’ installation?
Yes. Because we flash the module with your car’s specific VIN, it will recognize all the existing security keys and components. Once installed, you will not need to take it to a dealer or mechanic for further programming. It’s designed to be a direct replacement and function immediately.
Will this fix my check engine light?
This module will resolve any check engine light and diagnostic trouble codes that are directly caused by a faulty ECM. However, if your vehicle has other underlying mechanical or electrical issues (e.g., a bad sensor or wiring problem), those issues will still need to be addressed separately.
Where is the ECM located on my vehicle?
On most 2015 Challenger, Charger, and 300 models, the ECM is located in the engine bay, typically on the passenger side near the firewall or shock tower. It is a silver metal box with several large electrical connectors.
Do I need to send my old part back?
No core charge is required for this part. You do not need to return your old, faulty engine computer to us.
