An Expert’s Note on Programming
From over two decades of hands-on experience, I can tell you that improper or incomplete ECM programming is the number one cause of post-installation failure. Many sellers ship blank units, forcing you to find a specialist. We saw a 2018 Chevy Sonic that had been to three different shops, each failing to program a generic computer correctly. The owner was about to give up. We sent them a Programmed 2017-2021 Buick Encore ECM (the same part number), and it started on the first try. The key is matching the software to the VIN before it ever leaves our facility. That’s not just a service; it’s the core of a successful, lasting repair.

Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as the programming is essential for the part to work.
Is any additional programming needed after installation?
In most cases, no. This ECM comes programmed to your VIN for engine and transmission operation. However, some vehicles may require a simple security relearn procedure (like a key cycle process) or a crank sensor relearn, which can be done with a capable scan tool. Instructions are often available online for your specific model.
Is this a plug-and-play part?
Yes, this part is designed to be as close to plug-and-play as possible. Once programmed to your VIN, it is ready for installation. You simply disconnect the battery, swap the old module with the new one, and reconnect the battery. A security relearn may be necessary as mentioned above.
How can I be sure this part will fit my vehicle?
Please check the fitment list provided in the description. This ECM replaces part numbers 12668986 and 12692201. Matching your original part number or confirming your vehicle is on the list is the best way to ensure compatibility. If you are unsure, please contact us with your VIN before ordering.
What is the difference between an ECM, ECU, and PCM?
The terms are often used interchangeably. ECM (Engine Control Module) and ECU (Engine Control Unit) typically refer to the same component. PCM (Powertrain Control Module) is a type of ECU that controls both the engine and the transmission. For your vehicle, this module serves as the central computer for the powertrain.
