Is Your GM Vehicle Running Rough? Get Back in Control.
A persistent Check Engine Light, unpredictable stalling, poor fuel economy, or strange shifting patterns can turn any drive into a stressful experience. These aren’t just annoyances; they’re often symptoms of a failing Engine Control Module (ECM)—the central computer of your vehicle. This isn’t a part you can afford to ignore. Restore the precision performance and reliability of your car, truck, or SUV with this direct-replacement, professionally programmed GM 12669318 Engine Control Module.
Common Symptoms of a Failing ECM & Your Direct Solution
If you’re experiencing any of the following, a faulty engine computer is a likely culprit:
- Illuminated Check Engine Light (CEL): Often with communication error codes like U0100 or internal processor failure codes like P0601, P0606.
- Engine Performance Issues: Noticeable hesitation, misfires, rough idling, or a significant loss of power.
- No-Start Condition: The engine cranks but refuses to start, even with a good battery and starter.
- Poor Fuel Economy: A sudden and unexplained drop in your vehicle’s MPG.
- Erratic Transmission Behavior: Harsh or delayed shifting, as the ECM plays a critical role in communicating with the transmission controller.
This module is the definitive solution. We take the guesswork and complexity out of the repair by programming it specifically to your vehicle’s unique Vehicle Identification Number (VIN) before it ever leaves our facility. This ensures all systems, from the anti-theft security to the fuel injectors, operate exactly as the manufacturer intended.

From the Technician’s Bench: Why VIN Programming is Non-Negotiable
In the past, you could often swap a computer from one vehicle to another. Those days are long gone. On modern GM vehicles, the ECM is the heart of a complex network. It’s linked to the anti-theft system, the instrument cluster, the ABS module, and more. Simply installing a non-programmed GM 12669318 Engine Control Module will result in a no-start condition every time. Our VIN-specific programming service correctly configures all these integrated systems, ensuring the module is recognized by your vehicle for a seamless and successful repair.
Frequently Asked Questions
How does the programming process work?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to access the latest official GM software for your specific make, model, and options. We then flash this software onto the module, making it a perfect match for your vehicle before we ship it.
Do I need to do anything after installation?
While the module is programmed for your engine and options, some vehicles may require a simple “Security Relearn” or “CASE Relearn” procedure after installation. These procedures can typically be performed without special tools and instructions are widely available online for your specific model.
Is this a brand-new part?
This is a high-quality, inspected, and tested component that meets or exceeds original equipment specifications. Each unit is verified to be fully functional before being programmed and shipped.
How do I find my vehicle’s VIN?
Your VIN can be found on a metal tag on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
What if my original part number is slightly different?
The provided list of compatible part numbers (e.g., 12692067, 12676230, 12662034) are all interchangeable with the GM 12669318 Engine Control Module. As long as your original part number is on our list, this module will work perfectly once programmed to your VIN.
