Frequently Asked Questions
What is VIN programming and why is it necessary?
VIN programming is the process of loading your vehicle’s specific software and calibration files onto the ECM. This is crucial because it tells the computer about your car’s engine, transmission, emissions equipment, and other options. Without it, the car may not start, run poorly, or have warning lights. We handle this for you before shipping.
Will I need to do anything after installing this ECM?
While our programming makes this a plug-and-play solution, some vehicles may require a simple ‘relearn’ procedure after installation, such as a Case Relearn or Security Relearn. These can often be performed with a capable scan tool and are standard procedure for this type of repair.
How do I find my vehicle’s part number to confirm a match?
The part number is printed on a sticker on your original ECM. While this unit fits multiple part numbers (12667002, 12666070, 12667189), the most important factor is our VIN programming, which ensures compatibility for your specific 2017 Buick Regal.
Is this a new or used part?
This is a high-quality, tested, and guaranteed functional component. Every unit is inspected and programmed with the latest software to ensure it meets or exceeds original performance standards, providing a reliable and lasting repair.
What if my original part number isn’t on your list?
If your part number is different but your vehicle is listed in the compatibility chart, please contact us with your VIN. GM often consolidates part numbers, and we can verify if this module is the correct, updated replacement for your original.
What does the one-year warranty cover?
This unit is backed by our one-year replacement warranty. This covers the module against any functional defects for one year from the date of purchase. We are committed to providing a reliable part that solves your problem.
