Is Your Acadia Giving You Headaches?
Is your 2012 GMC Acadia running rough, stalling unexpectedly, or displaying a stubborn check engine light that just won’t go away?

An Expert’s Note on VIN Programming
As a technician with over 20 years of experience, I can’t stress this enough: VIN programming is not optional on modern vehicles like your Acadia. The ECM is the central hub of a complex network that controls everything from the engine and transmission to the anti-theft system and even the dashboard gauges. An unprogrammed module simply cannot communicate with these other systems. By purchasing a programmed 2012 GMC Acadia ECM from us, you are bypassing the single biggest hurdle of this repair, ensuring all systems integrate correctly from the moment you turn the key.
Don’t let a faulty computer keep your family’s vehicle off the road. This is the most effective and efficient way to restore your vehicle’s health. By providing us with your VIN upon purchase, you are ordering a component that is tailored specifically for your SUV. Get the right part, the first time, with this fully programmed 2012 GMC Acadia ECM.
Frequently Asked Questions
Do I need to do any additional programming after installation?
No dealership programming is required. The module comes fully programmed to your VIN. You will only need to perform a simple security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. We include instructions for this easy process.
How do I provide my vehicle’s VIN?
You can add your 17-digit VIN in the ‘notes’ section during checkout. If you forget, don’t worry! We will contact you via email after your purchase to request the VIN before we program and ship your module.
Is this the correct ECM for my vehicle?
This module replaces part numbers 12651994, 12643248, 12652814, and AA69. It fits a wide range of GM vehicles, including the 2012 Acadia. Providing your VIN is the best way to guarantee 100% compatibility, as we will verify the fitment for you.
Will this fix my specific problem or check engine light?
If your vehicle’s issues have been correctly diagnosed as a faulty ECM, this part will resolve them. However, it’s important to ensure the ECM is truly the root cause, as other sensor or wiring issues can sometimes present similar symptoms.
