You aren’t just buying a part; you’re investing in a complete, vehicle-specific solution that guarantees a smooth installation and long-term reliability. We handle the complexity so you can get back on the road.

Frequently Asked Questions
Do I need to do any programming myself?
No. This ECM comes fully pre-programmed to the VIN you provide. The service is included in the price. It is designed to be a plug-and-play solution, though some vehicles may require a simple security or crankshaft variation (CASE) relearn procedure, which can be performed with a compatible high-level scan tool.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically find this on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this module compatible with my specific truck or SUV?
This ECM fits a very wide range of GM vehicles as listed in the compatibility chart. The most important step is providing us with your VIN. This allows us to load the exact software for your vehicle’s specific make, model, engine, and options, guaranteeing a perfect match.
My original ECM has a different part number. Will this still work?
Yes. This module, 12663391, is the latest service replacement for a number of older part numbers, including 12692067, 12676230, and others listed. Our VIN programming ensures it functions identically to your original, but with the benefit of updated factory software.
What is a CASE Relearn?
A Crankshaft Position System Variation (CASE) Relearn is a procedure that allows the ECM to learn the minor variations in the crankshaft position sensor. After installing a new ECM, performing this relearn with a capable scan tool is sometimes necessary to prevent a P0315 trouble code and ensure the most accurate misfire detection. While not always required for the vehicle to run, it is a recommended final step for optimal performance.
What if this doesn’t fix my vehicle’s problem?
While this programmed 2014-2016 CTS ECM is the definitive solution for a failed module, proper vehicle diagnosis is always key. We recommend confirming the ECM is the point of failure before purchasing. Our one-year replacement warranty covers the part itself in the event of a defect.
