Restore Peak Performance to Your Dodge Van
Is your 1996 or 1997 Dodge Ram Van suffering from frustrating issues like intermittent stalling, rough idling, a persistent check engine light, or even a complete no-start condition? These are classic signs of a failing Engine Control Module (ECM). The ECM is the brain of your vehicle, controlling everything from fuel mixture and ignition timing to transmission shifting. When it fails, it can cause a cascade of problems that can leave you stranded. This replacement engine computer, part number 56040250AF, is the definitive solution to get your reliable workhorse back on the road, running like it should.

From the Diagnostic Bay
We had a ’97 Dodge B2500 conversion van come into the shop that was driving the owner crazy. It would start and run fine for days, then suddenly stall at a stoplight and refuse to restart for an hour. The dashboard would display a ‘NO BUS’ message, indicating a communication breakdown. We checked all the usual suspects—power, grounds, sensors—and everything seemed fine. After hooking up an oscilloscope, we saw the 5-volt reference signal from the ECM was dropping out intermittently. We swapped in a pre-programmed module, and the van fired up instantly. The owner called a month later to say it hadn’t missed a beat since. These older Chrysler ECMs are notorious for internal component failure, and this was a textbook case.
Common Symptoms of a Failing Dodge Van ECM
- ✔ Persistent Check Engine Light (CEL) that won’t clear or points to multiple, unrelated sensor failures.
- ✔ Engine stalls unexpectedly, either while driving or at idle.
- ✔ Complete no-start condition where the engine cranks but will not fire up.
- ✔ Poor engine performance, including hesitation, misfires, and reduced power.
- ✔ A noticeable decrease in fuel economy.
- ✔ Harsh or erratic automatic transmission shifting, as the ECM controls shift points.
- ✔ Communication errors when trying to use a diagnostic scan tool.
- ✔ The ‘NO BUS’ message appearing on the digital odometer display.

Frequently Asked Questions
Is this ECM truly Plug & Play?
Absolutely. We program the unit with your van’s specific VIN and mileage before it ships. This ensures it communicates correctly with all other modules in your vehicle right out of the box, with no further programming needed.
Where is the ECM located on my 1996-1997 Dodge Van?
The Engine Control Module is typically located in the engine compartment, mounted to the center of the firewall. It’s a silver metal box with three large electrical connectors.
Will this fix my transmission shifting problems?
In many cases, yes. The ECM controls the 4-speed automatic transmission’s shift solenoids and line pressure. If your van is experiencing harsh shifts, delayed engagement, or is stuck in a single gear (limp mode), a faulty ECM is a very common cause.
What information do you need from me to program it?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. You can typically find the VIN on your dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Do I need any special tools for installation?
No special tools are required. Basic hand tools, such as a socket set to remove the mounting bolts and a flathead screwdriver to help release the connector clips, are all that’s needed. The most important step is to disconnect the negative battery terminal before you begin.
