An Expert’s Note on Programming: From over 20 years in diagnostics, I’ve seen countless issues arise from using generic, non-programmed modules.

Our process of programming this module specifically to your car’s VIN isn’t just a convenience; it’s a guarantee of electronic compatibility. We’re essentially giving your Regal its original ‘brain’ back, but with all the latest software knowledge from GM. This is the correct way to ensure a lasting repair.

Frequently Asked Questions
What is VIN programming and why is it necessary?
VIN programming is the process of loading your vehicle’s unique 17-digit Vehicle Identification Number and its specific software configuration onto the ECM. This is critical because it allows the module to communicate correctly with your car’s engine, transmission, anti-lock brakes, and security system. Without it, the vehicle will not start or run properly.
Do I need to do any additional programming after installation?
No. This module is sold as a plug-and-play solution. We handle all the programming before it ships, so you can install it without needing any special tools or a trip to the dealership.
Where do I provide my VIN?
After you complete your purchase, you will need to send us a message with your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your car.
How do I know if my ECM is the problem?
While the symptoms listed above are strong indicators, a definitive diagnosis from a qualified technician is always the best course of action. Common diagnostic trouble codes (DTCs) pointing to internal ECM failure include P0601 through P0606. A professional diagnosis can rule out wiring or sensor issues before you replace the module.
Is this compatible with other GM vehicles?
Yes, this ECM is compatible with a wide range of GM models and years, including certain Cadillac CTS, Chevy Impala, GMC Terrain, and more. Please check the detailed fitment list in our description to confirm compatibility with your specific vehicle.
What does the warranty cover?
This unit is backed by our one-year replacement warranty. This covers the part itself in the unlikely event of a failure within one year of the purchase date. Please contact us for any warranty-related inquiries.
