Get Your GM Vehicle Back on the Road with Confidence
Is your GMC Acadia, Chevy Equinox, or other GM vehicle suffering from frustrating and unpredictable engine problems? A faulty Engine Control Module (ECM) can cause everything from a no-start condition and poor fuel economy to random stalling and a dashboard full of warning lights. Don’t let a bad computer keep your daily driver sidelined. This is the simple, reliable, and affordable solution to restore your vehicle’s performance and get you back to your life.
Common Symptoms & Your Solution
If you’re experiencing any of the issues below, a failing ECM is the likely culprit:
- Complete no-start or intermittent starting issues
- Rough idling, stalling, or hesitation during acceleration
- Check Engine Light with communication error codes (like U0100)
- Specific diagnostic trouble codes (DTCs) such as P0606 (ECM Processor Fault)
- Poor engine performance and reduced fuel efficiency
- Erratic transmission shifting behavior
This genuine, used programmed 12669908 ECM is the definitive fix. We take the guesswork and high cost out of the equation. Before we ship it, our technicians flash the unit with the latest official GM software, perfectly matched to your vehicle’s unique Vehicle Identification Number (VIN).

An Expert’s Note on VIN Programming
“As a technician with two decades of experience, I’ve seen countless headaches caused by installing a used ECM without proper programming. You might buy a module from a salvage yard with the same part number, but it’s still ‘coded’ to the donor vehicle’s options and security system. This inevitably leads to no-start conditions or a cascade of error codes. Our process of programming this programmed 12669908 ECM to your VIN before it even leaves our facility is the single most important step in guaranteeing a successful repair. We handle the complex part so you can focus on the simple installation.”
Stop chasing symptoms and replace the core of your engine’s management system. By providing us with your VIN upon purchase, you are ensuring that the programmed 12669908 ECM you receive is the correct, updated, and ready-to-install solution for your vehicle.
Frequently Asked Questions
What does “VIN-programmed” mean?
It means we use your vehicle’s 17-digit Vehicle Identification Number (VIN) to load the correct, factory-specified software and calibrations onto this ECM. This ensures it works perfectly with your car’s specific engine, transmission, and options.
Do I need to do anything after installation?
Yes. In many cases, a vehicle anti-theft system (VATS) relearn is required for the vehicle to start. This is a standard procedure for any ECM replacement on these vehicles and can be performed by a qualified technician with the proper GM tools. Other vehicle-specific relearns, like for the crankshaft position sensor, may also be necessary.
Is this a new part?
No, this is a high-quality, fully tested used part that has been sourced from a salvaged vehicle. This allows us to provide a reliable and affordable solution for your repair needs.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. We cannot program and ship your ECM until we receive this information.
Will this fit my vehicle for sure?
This ECM fits many GM models. The best way to ensure compatibility is to match the service number (serv.no) on your current ECM to 12669908. Please also review the detailed fitment list on this page.
What if the part doesn’t fix my problem?
First, ensure all necessary relearn procedures have been completed by a qualified technician. If the unit is determined to be faulty, it is backed by our one-year replacement warranty, giving you peace of mind with your purchase.
