End Your Engine Troubles and Drive with Confidence Again

Is your vehicle suffering from a frustrating no-start condition, a persistent Check Engine Light, or unpredictable performance? A failing Engine Control Module (ECM) is often the culprit, leaving you stranded and stressed. This isn’t just an inconvenience; it’s a disruption to your daily life. We offer the definitive solution: a reliable, used GM Engine Control Module, service number 12669908, professionally programmed to your vehicle’s specific VIN before it ever leaves our facility.

Common Symptoms & Your Solution

If you’re experiencing any of the following, this pre-programmed 12669908 ECM is the component you need to restore your vehicle’s health:

  • Persistent Check Engine Light (CEL) with codes related to internal processor failure (e.g., P0601, P0606) or communication errors.
  • The engine cranks but refuses to start.
  • Stalling, hesitation, or rough idling for no apparent reason.
  • Noticeable decrease in fuel economy.
  • Transmission shifting issues or other electronic module malfunctions.

Instead of paying dealership prices for a new module and programming, you get a cost-effective, dependable part that is ready for installation and final relearn procedures, getting you back on the road quickly and affordably.

An Expert’s Note on Installation Success

As a technician with over two decades of experience, I can’t stress this enough: the key to a successful ECM replacement is twofold. First is the initial VIN programming, which we handle for you. This ensures the computer has the correct operational software for your exact vehicle. The second, and equally critical, step is the on-vehicle security relearn (often called the ‘theft relearn’). Modern GM vehicles have a sophisticated anti-theft system that links the ECM to other modules. If the car doesn’t start after installation, performing this quick procedure with the proper scan tool is a standard and necessary final step. Taking a moment to ensure all relearns are done correctly is the difference between a frustrating experience and a smooth, successful repair.

Frequently Asked Questions

Why do I need to provide my VIN?

Your Vehicle Identification Number (VIN) is essential for us to program the 12669908 ECM with the exact software and calibrations specified by GM for your vehicle’s engine, transmission, and options. This step is critical for proper function and avoids compatibility issues.

What is a ‘theft relearn’ and will I need to do it?

A theft deterrent relearn synchronizes the new ECM with your vehicle’s security system. If the vehicle does not start after installation, this procedure is required. It must be performed using a compatible high-level scan tool or the GM TIS2Web programming system. This is the responsibility of the installer.

Is this a new part?

No, this is a genuine, used OEM part that has been carefully sourced from a salvaged vehicle. It has been inspected and is ready to be programmed and installed, offering a reliable and affordable alternative to a new unit.

How do I confirm this ECM is right for my car?

The best way to ensure compatibility is to match the service number (serv.no) on your original ECM to 12669908. While this part fits many models listed, the service number is the most accurate identifier.

What other relearns might be needed?

Depending on your specific vehicle, additional procedures like a crankshaft position variation relearn or injector flow rate programming may be necessary to ensure optimal performance. These are standard procedures after replacing a major electronic component.

What does the warranty cover?

This part is backed by a one-year replacement warranty. In the unlikely event the unit fails within one year of purchase, we will provide a replacement part.
