Expert Diagnostic Insight
With over two decades of hands-on diagnostics, I’ve seen how a mismatched or improperly programmed computer can create more problems than it solves. The ECM is the brain, and it must have the correct ‘memories’โthe software calibrationsโfor your specific car. Our process of flashing this genuine GM 12669908 ECM with the correct, VIN-specific software is the most critical step. It ensures the engine, transmission, fuel system, and anti-theft systems all communicate flawlessly, just as the factory intended. You’re not just buying a part; you’re getting a fully integrated brain transplant for your vehicle.
Important Installation Information
After you purchase, please provide us with your vehicle’s VIN. We cannot ship the part until it has been programmed. Upon installation, if the vehicle does not start, a Vehicle Theft Deterrent System Relearn must be performed. This procedure syncs the new ECM with your car’s security system and requires a professional tool like the GM tis2web programming system. This, along with any other necessary relearns (e.g., crankshaft variation, injector setup), is the responsibility of the installer.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
After completing your purchase, please send us a message with your 17-digit Vehicle Identification Number (VIN). We will program the 12669908 ECM and then ship it to you.
Is this a new part?
No, this is a genuine, used OEM part that has been carefully removed from a salvaged vehicle. It has been inspected and tested to ensure it is fully functional before being programmed for your vehicle.
What is a theft relearn and why do I need it?
The theft relearn is a security procedure that syncs the new ECM to your vehicle’s ignition keys and anti-theft system. Because the computer came from a different vehicle, this step is often necessary to allow the engine to start. It typically requires a professional scan tool.
Will this fit my car if my part number is different?
You must match the service number (serv.no) exactly. This listing is for service number 12669908. Please check the label on your current ECM to confirm compatibility before ordering.
Is programming really included?
Yes, the programming service is included in the price. We flash the module with the latest updates from GM specific to your VIN, saving you hundreds of dollars in dealership fees.
