Get Your Vehicle Running Right Again
Is a persistent Check Engine Light driving you crazy? Are you dealing with frustrating issues like a no-start condition, rough idling, stalling, or abysmal fuel economy? A failing Engine Control Module (ECM) is often the culprit, acting like a broken brain for your vehicle. This isn’t just an inconvenience; it’s a problem that affects your vehicle’s reliability and your peace of mind. Stop throwing parts at the problem and get the definitive solution with our pre-programmed engine computer.
Common Symptoms & Your Solution
If your technician has pulled diagnostic trouble codes (DTCs) like P0601, P0606, or various communication errors (U-codes), it’s a strong indicator that the ECM has failed. You might also experience one or more of the following:
- Engine misfires or runs poorly
- Transmission shifting problems
- Vehicle won’t start at all
- Significantly reduced power and fuel efficiency
- Check Engine Light is always on
This fully tested, genuine GM ECM is the core of your vehicle’s management system, and we make the replacement process simple. By providing your Vehicle Identification Number (VIN) during checkout, you receive a programmed 12644446 ECM that is flashed with the latest GM software updates specifically for your car. It arrives ready to install, eliminating the need for an expensive trip to the dealership for programming.

A Veteran Technician’s Tip: In modern GM vehicles, the ECM is tied directly to the anti-theft and security system (VATS/Passlock). You can’t simply grab a used computer from a salvage yard and expect it to work—the car won’t start. That’s why our VIN programming service is so critical. We match the module to your vehicle’s unique identity, saving you the headache and expense of towing your car to a dealer for a complex and costly security relearn procedure. This is how you fix it right, the first time.
Don’t let a faulty computer keep your car off the road. Take control of your repair with a reliable, ready-to-install programmed 12644446 ECM and restore the dependable performance you count on every day.
Frequently Asked Questions
How does the programming process work?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to access the official GM database and flash the ECM with the exact software and calibrations for your specific make, model, year, and options. This ensures perfect compatibility.
Will I need to do anything after installation?
In most cases, the unit is plug-and-play. However, some vehicles may require a simple “security relearn” procedure, which can typically be done without special tools and takes about 30 minutes. We can provide instructions for this if needed. It does not require a trip to the dealer.
Is this a brand new part?
No, this is a high-quality, used OEM part that has been sourced from a salvaged vehicle. Each unit is thoroughly inspected and tested to ensure it is fully functional before being programmed and shipped.
How do I find my 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.
Will this fix my specific problem?
This programmed 12644446 ECM is a direct solution for a failed computer. While it resolves a wide range of issues, it’s crucial that your vehicle has been properly diagnosed. This part will not fix problems related to other faulty components like sensors, wiring, or mechanical parts.
