Frequently Asked Questions

Absolutely not. The main benefit of our service is that this Programmed 12630457 ECM arrives at your door fully flashed with the latest GM software for your specific vehicle. All we need is your VIN during checkout. It’s ready for installation right out of the box.
What information do you need from me?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This allows us to load the exact, correct software for your car’s specific options and configuration.
Will this fix my Check Engine Light?
If the Check Engine Light is on due to an internal failure of the original ECM, then this part is the correct solution. It’s crucial to have a proper diagnosis to confirm the ECM is the point of failure, as other sensors or wiring issues can also trigger a warning light.
Is any other procedure needed after installation?
In many GM vehicles, you may need to perform a simple security relearn procedure. This typically involves cycling the ignition key and can be done by you in your driveway in about 10-15 minutes without any special tools. This syncs the new ECM with your vehicle’s anti-theft system.
How can I be sure this part fits my vehicle?
Please check the service number on your original ECM to see if it matches 12630457 or any of the other interchangeable numbers listed. You should also use the detailed fitment list on this page to confirm your make, model, year, and engine option.
