Pro Tip from a 20-Year Tech: Before replacing your ECM, always double-check your fundamentals. Ensure your battery is fully charged and passes a load test, and inspect your main engine and chassis ground connections. A weak battery or a corroded ground strap can mimic ECM failure symptoms and cause communication errors. A few minutes of inspection can save you from replacing a part that isn’t faulty.

Frequently Asked Questions
What exactly is VIN programming?
VIN programming is the process of loading your vehicle’s specific software and calibrations onto the engine control module. This includes information about your engine, transmission, emissions equipment, and other factory options. It ensures the ECM communicates perfectly with all other modules on your van, just like the original unit did.
Do I need to do anything after I install this ECM?
In most cases, this is a direct plug-and-play installation. However, some vehicles may require a security relearn procedure, which can typically be done without special tools. We recommend consulting a service manual for your specific vehicle’s post-installation requirements, if any.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is essential for the part to function.
My original part number isn’t 12668866, but it’s on your list. Will this work?
Yes. The part numbers listed (like 12668994, 12643636, etc.) are all interchangeable. As long as your original part number is in our fitment list, this module will be the correct replacement once it is programmed to your VIN.
Is this a brand new part?
This is a high-quality, inspected, and tested recycled OEM part. It has been verified to meet or exceed original factory specifications and is programmed with the newest software updates available from the manufacturer for your vehicle.
