Restore Peak Performance to Your 1996-1997 Dodge
Is your 1996 or 1997 Dodge Ram or Van running rough, stalling unexpectedly, or refusing to start? These frustrating and often intermittent issues can frequently be traced back to a failing Engine Control Module (ECM). The ECM is the brain of your vehicle’s engine management system, controlling everything from fuel injection and ignition timing to transmission shifting and emissions. When it begins to fail, it can cause a cascade of problems that are difficult to diagnose. This direct-fit replacement engine computer, part number 56040372AA, is the definitive solution to get your trusted Dodge back on the road with reliability and confidence.
From the Diagnostic Bay
We had a ’97 Dodge Ram 2500 Van come into the shop with a classic complaint: it would run fine for about 20 minutes, then suddenly stall and refuse to restart until it cooled down completely. The owner had already replaced the crank sensor, cam sensor, and even the fuel pump, with no luck. Scans showed no consistent codes, just a jumble of communication errors that would appear after the stall. We suspected the ECM was failing under heat. After letting the van run in the bay until it stalled, we used a can of circuit cooler and sprayed the ECM directly. Within 30 seconds, the van fired right back up. This confirmed a thermal failure inside the computer. We installed one of these pre-programmed units, and the van has been running perfectly ever since. It’s a textbook example of how a failing 1996-1997 Dodge Engine Computer can mimic other component failures.
Is Your Dodge Showing Signs of a Failing ECM?
A faulty engine computer can manifest in numerous ways, often mimicking other sensor or component failures. If you’re experiencing any of the following symptoms, your ECM is a likely culprit.

Frequently Asked Questions
Do I need to have this computer programmed by a dealer?
No. This engine computer arrives at your door fully programmed to your vehicle’s VIN. It is a true plug-and-play solution, requiring no additional programming or flashing. Simply install it, connect the battery, and start your vehicle.
Where is the ECM located on my 1996-1997 Dodge Van?
The Electronic Control Module (ECM) is located on the center of the firewall in the engine bay. It is a silver metal box with three large electrical connectors. Access is straightforward, making for a simple replacement.
Will this fix my check engine light?
If the check engine light is caused by a fault within the original ECM, then yes, this replacement part will resolve the issue. However, it’s crucial to ensure that any diagnostic trouble codes (DTCs) related to external sensors or wiring are addressed before condemning the computer.
Is this compatible with my Dodge Ram truck?
While this ECM is primarily listed for the 1500, 2500, and 3500 Van models with the 5.2L V8, it shares architecture with the Ram trucks of the same era. Please verify that your original part number is on our compatibility list to ensure a perfect match for your truck.
What is the most common cause of failure for these ECMs?
The most common failures are due to age, heat cycles, and vibration. Over time, internal solder joints can crack, and electronic components can fail, leading to the intermittent issues described. This is especially common on modules mounted on the firewall, where they are exposed to significant engine heat.
