Get Your Workhorse Running Right Again

This is the brain of your engine, and when it fails, everything grinds to a halt. We offer the definitive, no-nonsense solution: a professionally programmed 12606126 ECM, flashed with the latest GM software updates specifically for your vehicle’s VIN.

From the Shop Floor: We had a contractor come in with his ’06 Silverado 3500. It would crank but not start, and his regular mechanic had already replaced the fuel pump and injectors with no luck. The truck was his livelihood, and he was losing money daily. We diagnosed a failed ECM. Instead of a long wait and a huge bill from the dealer, we installed this exact Programmed 12606126 ECM. After a quick security relearn, the truck fired up on the first try and ran smoother than it had in years. He was back on the job site the very next morning. That’s the difference the right part makes.
Frequently Asked Questions
What do I need to do after I purchase this ECM?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). We use this to load the correct, updated software for your specific truck or van before we ship the part to you.
Is this unit truly plug-and-play?
Yes, because we program it to your VIN, it eliminates the need for dealer-level programming tools. In some vehicles, you may need to perform a simple security or anti-theft relearn procedure, which can typically be done without special tools and takes about 30 minutes. Instructions are widely available online for this process.
How can I be sure this will fix my truck’s problem?
This ECM will resolve issues directly caused by a faulty engine computer. If your vehicle exhibits symptoms like a no-start condition, stalling, communication error codes, or other issues listed above, and other potential causes have been ruled out, this is the most reliable solution.
Where can I find my vehicle’s VIN?
Your VIN can be found on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
This ECM replaces multiple part numbers. Are they all the same?
Yes, this module is the correct hardware replacement for all the listed part numbers, including 19260753, 12588335, 12606127, and others. The critical factor is the VIN-specific software we install, which makes it a perfect match for your vehicle’s systems.
