Restore Your Chevy’s Reliability and Performance
Is your Chevrolet Trax, Cruze, or Sonic giving you headaches?

Expert Insight: Why VIN Programming is Non-Negotiable
In modern vehicles, the ECM is more than just an engine controller; it’s the hub of a complex communication network. It needs to ‘shake hands’ with the transmission module, the anti-lock brake system, the instrument cluster, and even the key immobilizer. Flashing the unit to your specific VIN is the only way to ensure these components recognize each other and work together seamlessly. Installing a non-programmed module is a guaranteed recipe for a no-start condition and a dashboard full of warning lights. Our service handles this critical step for you, making your repair as smooth as possible.

Frequently Asked Questions
Do I need to do any programming myself?
No. This ECM arrives fully programmed to the VIN you provide. The installation is plug-and-play, and it is ready to be installed as soon as you receive it. In some cases, a simple security relearn procedure may be required, which you can typically do yourself without any special tools.
Where do I provide my vehicle’s VIN?
After you complete your purchase, we will send you an email requesting your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as it is essential for the programming process.
Is this compatible with other part numbers?
Yes, this ECM is a direct replacement for several part numbers, including 12679199, 12642927, 12636386, 12621466, and 12630789. Please check the fitment list to confirm it matches your vehicle’s make, model, and year.
How do I know for sure that my old ECM is the problem?
While the symptoms listed above are strong indicators of a failing ECM, we always recommend a thorough diagnosis by a qualified mechanic. This ensures that other potential issues, such as wiring problems or faulty sensors, have been ruled out before you replace the module.
Will this fix my automatic transmission shifting issues?
It can. The ECM works directly with the Transmission Control Module (TCM) to ensure smooth shifting. If the ECM is sending bad data, it can cause erratic shifting. However, transmission problems can also stem from the TCM itself or mechanical issues, so a full diagnosis is recommended.
