Is Your 2014 Dodge Ram Running Rough? It Could Be the ECM.
If you’re dealing with frustrating and unpredictable issues in your 2014 Dodge Ram 2500 or 3500, such as stalling, a persistent check engine light, or a no-start condition, the root of the problem might be its most critical component: the Engine Control Module (ECM). The ECM is the central computer of your truck, responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it begins to fail, it can cause a cascade of problems that are often difficult to diagnose, leading to wasted time and money on unnecessary repairs.
From the Diagnostic Bay
We once had a 2014 Ram 3500 with the 5.7L Hemi come in on a tow truck. The owner had already replaced the fuel pump and crankshaft position sensor trying to solve an intermittent stalling issue that left him stranded twice. The truck would run fine for days, then suddenly die at a stoplight and refuse to restart for an hour. Our diagnostics showed that the fuel pump relay wasn’t receiving its command signal from the ECM during the no-start events. We traced the wiring and found no faults. The issue was an internal failure in the ECM’s driver circuit for that specific relay. Installing a correctly programmed replacement ECM solved the problem permanently, saving the owner from further guesswork and frustration.
Common Symptoms of a Failing 2014 Dodge 2500 ECM
- ✔ Persistent Check Engine Light: You may see codes related to sensor circuits (e.g., P0107, P0335), communication errors (U-codes), or internal processor faults.
- ✔ Engine Stalling or Misfiring: The engine may stall unexpectedly while driving or at idle, and you might experience rough running or noticeable misfires.
- ✔ No-Start Condition: The engine cranks but refuses to start, often due to a lack of spark or fuel injector pulse commands from the ECM.
- ✔ Poor Performance and Fuel Economy: A failing ECM can’t properly calculate the air-fuel mixture, leading to a significant drop in power and an increase in fuel consumption.
- ✔ Transmission Shifting Issues: The ECM works closely with the transmission controller. A faulty ECM can cause harsh shifting, delayed engagement, or the transmission going into limp mode.
- ✔ Failure to Communicate with Scan Tools: If your diagnostic tool cannot connect to the engine computer, it’s a strong indicator that the module itself has failed.
The Plug-and-Play Solution: Your 2014 Dodge 2500 ECM
Replacing the ECM on a modern vehicle isn’t as simple as just swapping the part. The module contains vehicle-specific security information, including the Vehicle Identification Number (VIN), which must match the rest of the truck’s systems. This typically requires an expensive trip to the dealership for programming. Our solution eliminates that step. This engine computer is a direct-fit replacement for your 2014 Dodge Ram, and it arrives at your door fully programmed to your truck’s specific VIN and mileage. It is a true plug-and-play solution.
Simply disconnect the battery, locate and unbolt your old module on the right-hand rear of the engine compartment, disconnect the electrical connectors, and install this unit in its place. Reconnect the connectors and the battery, and you’re ready to go. There is no need for additional programming or dealer intervention, getting you back on the road quickly and affordably.

Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. This module comes fully programmed to your vehicle’s specific VIN and mileage. It is a 100% plug-and-play unit that requires no further programming or dealer visits for installation.
Where is the ECM located on my 2014 Dodge Ram?
The Engine Control Module is located in the engine bay, on the right-hand (passenger) side, towards the rear near the firewall.
What information do you need from me when I order?
To ensure proper programming, we require your vehicle’s 17-digit Vehicle Identification Number (VIN) and current mileage at the time of purchase. Please provide this information during checkout.
Will this fix my check engine light?
If the check engine light and associated symptoms are caused by a faulty ECM, this replacement part will resolve the issue. It’s essential to have a proper diagnosis to confirm the ECM is the point of failure before ordering.
Is this module compatible with other part numbers?
Yes, this unit is a direct replacement for part numbers 68066900AB, 05150854AC, and 68153868AE. If your original module has one of these numbers, this part will work for your vehicle.
What’s the difference between an ECM and a PCM?
The terms are often used interchangeably. ECM (Engine Control Module) specifically refers to the engine’s computer. PCM (Powertrain Control Module) is a more integrated unit that controls both the engine and the transmission. For this 2014 Dodge Ram, this module functions as the PCM, managing both systems.
