Restore Your Vehicle’s Performance and Reliability
Experiencing erratic engine behavior, a persistent Check Engine Light, or a frustrating no-start condition in your GM vehicle? A failing Engine Control Module (ECM) is often the root cause, disrupting your daily life and threatening a costly dealership repair. This professionally programmed engine computer is the smart, reliable solution to get your car, truck, or SUV running smoothly again and restore your driving confidence.
Common Symptoms & Your Solution

An Expert Technician’s Insight
As a technician with over two decades of hands-on experience, I’ve seen how modern vehicle security systems can complicate repairs. Your car’s ECM is tied directly to its anti-theft system. That’s why a ‘theft relearn’ is a standard and sometimes necessary procedure after replacing the module. While we handle the complex VIN programming to ensure the software is perfect, this final ‘handshake’ between the new ECM and your car’s security components is crucial. It’s a quick process for any qualified mechanic with a GM diagnostic tool, and being prepared for this step is the key to a smooth, successful, and stress-free repair. A properly installed and configured programmed 12669908 ECM will restore your vehicle’s factory performance.
By choosing our programmed 12669908 ECM, you are not just buying a part; you are investing in a comprehensive solution designed to solve your problem efficiently and get you back on the road safely.
Frequently Asked Questions
What information do I need to provide after ordering?
After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to program the ECM with the correct software and calibrations for your specific car.
Is this part truly “plug and play”?
We perform the critical programming to your VIN, which is the most complex step. However, upon installation, additional procedures may be required. Most commonly, a vehicle anti-theft system relearn (VATS relearn) will be needed. Other vehicle-specific setups like a crankshaft variation relearn may also be necessary. This is standard for this type of repair.
What is a “theft relearn” and why is it needed?
A theft relearn is a security procedure that syncs the new ECM with your vehicle’s existing anti-theft system and keys. Without this ‘handshake,’ the system may prevent the engine from starting, assuming the module is from a stolen vehicle. It requires a compatible scan tool, such as the GM tis2web system.
Who should install this ECM?
We strongly recommend installation by a certified automotive technician or an experienced mechanic who has access to the proper diagnostic tools required for the final relearn procedures. While the physical replacement is straightforward, the electronic setup is critical for proper function.
How do I know for sure that my ECM is the problem?
While the symptoms listed are common indicators of ECM failure, they can also be caused by other issues. The best way to be certain is to have a professional diagnosis performed by a qualified mechanic. This ensures you are replacing the correct part and avoids unnecessary expenses.
What does the one-year warranty cover?
The warranty covers the ECM unit itself. In the unlikely event the module fails within one year of the purchase date, we will provide a replacement unit. The warranty does not cover labor, diagnostic costs, or shipping fees.
