This professionally programmed ECM is the definitive, hassle-free solution to restore your Enclave to its original, smooth-running condition.

An Expert’s Note on VIN Programming
In modern vehicles like your Enclave, the ECM is much more than just an engine controller; it’s the hub of a complex communication network. Programming the module to your specific Vehicle Identification Number (VIN) is absolutely critical. This process syncs the ECM with your vehicle’s security system (immobilizer), transmission, ABS, and even body control modules. A generic, non-programmed unit simply will not work. We take care of this essential step for you, ensuring that when your part arrives, it’s a true plug-and-play solution that integrates seamlessly with your vehicle’s unique systems.

Frequently Asked Questions
Do I need to get this computer programmed?
No. This ECM comes fully pre-programmed to your vehicle’s VIN before we ship it. It is ready for installation right out of the box, saving you time and the expense of a dealership visit.
What information do you need from me?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. We cannot program or ship the part without it. You can typically find your VIN on the driver’s side of the dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of your existing ECM (as confirmed by a proper diagnosis), then this part will resolve the issue. It’s always recommended to have a professional diagnosis to ensure you are replacing the correct part.
Is any other procedure required after installation?
In many GM vehicles, a simple security relearn procedure may be necessary after installation. This can typically be done without any special tools and involves a sequence of key turns. We include straightforward instructions to guide you through this quick process.
Which part numbers does this ECM replace?
This unit is a direct replacement for original GM part numbers 12667002, 12666070, and the primary part number 12667189. If your original module has one of these numbers, this is the correct part for you.
