Common Symptoms & Your Solution
A faulty ECM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, this Programmed GM ECM 12628911 is the component you need to restore proper function:
- Persistent Check Engine Light (CEL) with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0603, P0605, or P0606.
- Unexplained drops in fuel economy.
- Engine stalling, sputtering, or misfiring.
- Harsh or erratic automatic transmission shifting.
- Complete no-start condition where the engine cranks but will not fire.
- Loss of power and poor acceleration.
Replacing the module with a non-programmed unit from a salvage yard will not work due to anti-theft systems and specific vehicle calibrations. Our professional programming service makes this a seamless, effective repair.

Expert Insight: The ‘Brain’ Transplant for Your Vehicle
Think of the ECM as your vehicle’s brain. It controls everything from fuel injection and ignition timing to transmission shifts. When it fails, the entire system is compromised. Many people are tempted to grab a used module from a junkyard, thinking it’s a cheap fix. However, that used ‘brain’ is programmed for a completely different vehicle with different options, security keys, and mileage. It simply won’t work and can even cause further electrical issues. Our process is like a perfect organ transplant; we take a quality, tested module and program it to be an exact digital twin of your original, ensuring it communicates flawlessly with every other component in your vehicle from the moment you plug it in.
Frequently Asked Questions
Do I need to do any programming after I receive this?
No. This Programmed GM ECM 12628911 is delivered to you fully flashed and ready for installation. In some cases, a simple crankshaft variation relearn or security relearn procedure may be necessary, which can be done without a dealer scan tool. Instructions are widely available for this process.
Where do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we have this information, as the programming is specific to your exact vehicle.
How do I know for sure that my ECM is the problem?
While the symptoms listed are strong indicators, it is always best to have your vehicle properly diagnosed by a qualified mechanic. Common ECM-related trouble codes (P0600-P0606) are a very strong sign that the module itself is the point of failure.
Is this a brand new part?
This is a high-quality, fully tested replacement part that has been verified to meet or exceed original equipment specifications. It is programmed with the newest software from GM to ensure optimal performance and longevity.
What does the one-year replacement warranty cover?
This unit is backed by our one-year replacement warranty, which covers any defects in the module itself. If the unit fails within one year of the purchase date, we will provide a replacement part.
