Get Your Vehicle Running Right with a VIN-Programmed Engine Computer
There’s nothing more frustrating than a vehicle that won’t start, runs poorly, or constantly throws a check engine light. Your vehicle’s Engine Control Module (ECM) is its brain, and when it fails, it can cause a cascade of confusing and debilitating problems. This isn’t just an inconvenience; it’s a disruption to your daily life. We offer the definitive, hassle-free solution: a high-quality replacement programmed 12628911 ECM, flashed specifically to your vehicle’s VIN before it ever leaves our facility.
Is Your GM Vehicle Acting Up? Common Symptoms & Your Solution
A failing ECM can manifest in many ways, often mimicking other component failures. If you’re experiencing any of the following, a faulty engine computer is a likely culprit:
- Check Engine Light: An illuminated CEL with communication-related codes (like P0601, P0606) or multiple random misfire codes is a classic sign.
- No-Start Condition: The engine cranks but refuses to start, even with a good battery and fuel supply.
- Stalling & Poor Performance: Your vehicle may stall unexpectedly, hesitate during acceleration, or suffer from a noticeable loss of power and fuel economy.
- Erratic Shifting: The ECM plays a crucial role in transmission control. A bad unit can cause harsh or unpredictable shifting.
This VIN-programmed engine computer is the direct solution to these issues, restoring your vehicle’s factory performance and reliability without the exorbitant cost and scheduling headaches of a dealership visit.

From the Technician’s Bench: Why VIN Programming is Non-Negotiable
In the past, you could often swap a computer from one car to another. Those days are long gone. Modern GM vehicles use complex anti-theft systems (like Passlock or VATS) that are tied directly to the vehicle’s VIN stored in the ECM. Installing a non-programmed module will result in a no-start condition every time. Our pre-programming service handles this critical step for you. We ensure the security handshake is correct, all emissions parameters are set, and transmission shift points are calibrated for your exact vehicle. This is the secret to a successful, stress-free repair.
Don’t let a faulty computer keep you sidelined. By ordering this programmed 12628911 ECM, you’re not just buying a part; you’re buying a complete, reliable solution that restores your vehicle and your peace of mind. Simply provide your VIN during checkout, and we’ll handle the rest.
Frequently Asked Questions
How do I provide my VIN?
You can enter your 17-digit Vehicle Identification Number (VIN) in the notes section during the checkout process. This is essential for us to program the module correctly for your specific vehicle.
Is any additional programming required after installation?
In most cases, no. Our goal is to provide a plug-and-play solution. However, some GM vehicles may require a simple, 10-15 minute security relearn procedure that can be done without any special tools. We include instructions for this common procedure.
Will this fix my specific problem?
This programmed 12628911 ECM is a direct solution for a failed engine computer. While it resolves the common symptoms listed above, it’s always best to have a proper diagnosis performed to confirm the ECM is the root cause of your issue before ordering.
What does ‘interchangeable service number’ mean?
GM often releases updated versions of a part under a new service number. The list of numbers (like 12636659, 12628993, etc.) shows all the part numbers that this specific module can replace, guaranteeing you receive a compatible and updated component.
Where is the VIN located on my vehicle?
You can typically find your VIN on a plate on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
