Is Your 2014 Dodge Ram Truck Running Rough?
There’s nothing more frustrating than when your dependable 5.7L Hemi-powered Dodge truck starts acting up. Whether you’re dealing with a persistent check engine light, sudden stalling, or a complete no-start situation, the source of the problem can often be traced back to a failing Engine Control Module (ECM). The ECM is the brain of your truck’s operation, managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it fails, it can cause a wide range of confusing and debilitating symptoms, leaving your powerful workhorse stranded.
From the Diagnostic Bay
We had a 2014 Dodge 2500 with the 5.7L Hemi come in on a tow truck. The owner was at his wit’s end. The truck would start and run fine when cold, but after about 20 minutes of driving, it would sputter, stall, and refuse to restart until it cooled down completely. He had already replaced the crank sensor and a fuel pump with no luck. After hooking up our diagnostic scanner, we noticed we were losing communication with the ECM as soon as the engine bay got hot. A thermal test confirmed our suspicion: the processor on the original ECM was failing under heat. We installed one of our pre-programmed modules, and the truck has been running flawlessly for him ever since. It’s often the last part people suspect, but a critical one.
Symptoms of a Failing 2014 Dodge 3500 Engine Computer
A faulty ECM can manifest in numerous ways. If you’re experiencing any of the following issues, your engine computer could be the culprit. Look out for:
- ✔ Check Engine Light: An illuminated check engine light is the most common sign. You may see codes related to module communication (U-codes), sensor reference voltage, or multiple unrelated component failures.
- ✔ Engine Stalling or Misfiring: The engine may stall unexpectedly while driving or at idle. You might also notice rough idling, hesitation during acceleration, or random misfires.
- ✔ No-Start Condition: The engine cranks but refuses to start. This can happen intermittently or become a permanent issue, indicating the ECM is not properly firing the ignition coils or fuel injectors.
- ✔ Poor Fuel Economy: If the ECM cannot accurately calculate the air-fuel mixture, you may see a sudden and significant drop in your truck’s MPG.
- ✔ Inconsistent Transmission Shifting: The ECM works closely 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).
- ✔ Apparent Failure of Multiple Sensors: If your scanner shows codes for multiple, unrelated sensor failures simultaneously, it’s a strong indicator that the computer itself, which powers those sensors, is the root cause.

Frequently Asked Questions
Is this module truly Plug and Play?
Yes. We program the module with your truck’s specific VIN and mileage before shipping. This ensures it will integrate seamlessly with your vehicle’s existing systems, including the anti-theft security system. No further programming is required.
What information do you need from me?
During the checkout process, we will require your vehicle’s 17-digit VIN and the current mileage. This is essential for the programming service. Please double-check your VIN for accuracy to ensure a perfect match.
Where is the ECM located on my 2014 Dodge Ram truck?
On the 2014 Dodge 2500 and 3500 models with the 5.7L Hemi engine, the Electronic Control Module is typically located in the engine compartment on the right-hand (passenger) side, often near the firewall or inner fender.
Will this fix my check engine light?
This module will resolve the check engine light and any associated trouble codes if the ECM itself is the cause of the fault. It is crucial to have your vehicle properly diagnosed to confirm the ECM is the point of failure before ordering.
Do I need any special tools for installation?
No special tools are required for the installation. Basic hand tools, such as a socket set, are all that’s needed to disconnect the battery, remove the old module, and install the new one. The entire process can typically be completed in under an hour.
