An Expert’s Note on VIN Programming
Many sellers offer ‘blank’ modules, leaving you stranded with a part that won’t start your car. The ECM must communicate perfectly with every other module, from the transmission to the anti-theft system. Our VIN-specific programming ensures all these systems handshake correctly from the moment you turn the key, just as the factory intended. This critical step is the difference between a successful, 15-minute repair and a costly tow back to the shop.
Don’t let a faulty computer keep your car off the road. This Programmed 12651994 ECM is the most reliable and straightforward way to solve your vehicle’s electronic issues and restore its performance.
Frequently Asked Questions
Do I need to do any additional programming myself?
Absolutely not. This ECM is a true plug-and-play solution. We handle all the programming based on the VIN you provide, so it’s ready for installation right out of the box. Some vehicles may require a simple security relearn procedure, which can be done without any special tools and takes only a few minutes.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is essential for the programming process.

What if my original part number is slightly different?
The part numbers 12651994, 12643248, and 12652814 are often interchangeable. As long as your vehicle is on the compatibility list and your original module is one of these numbers, this unit will function correctly once programmed to your VIN.
