Restore Peak Performance to Your GM Vehicle
Is your 2009-2010 Chevrolet Tahoe, Silverado, or other compatible GM vehicle suffering from frustrating and unpredictable engine problems? A faulty Engine Control Module (ECM) is often the culprit behind issues like stalling, poor fuel economy, a persistent check engine light, or a no-start condition. The ECM is the brain of your engine, managing critical functions like fuel delivery, ignition timing, and emissions. When it fails, the entire vehicle’s performance and reliability are compromised. This direct-fit Engine Control Module, part number 12625455, is the definitive solution to get your truck or SUV running like new again.
From the Diagnostic Bay
I remember a 2009 Silverado 2500 that came in on a tow truck. The owner was at his wit’s end. The truck would run fine for days, then suddenly stall at a stoplight and refuse to restart for an hour. He had replaced the fuel pump and crank sensor, but the problem persisted. Our scan tool showed intermittent communication loss with the ECM. After confirming the wiring harness was solid, we knew the module’s internal circuits were failing. We installed one of these VIN-programmed ECMs, and the truck fired up instantly. The customer called a week later, overjoyed that his truck was finally reliable again. It’s a classic case where chasing symptoms doesn’t work; you have to address the root cause.

Do I need to get this ECM programmed?
No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s 17-digit VIN when you place your order, and the module will arrive ready for installation with the latest GM software for your specific vehicle.
Is this a difficult part to install?
For most vehicles listed, the ECM is located in the engine bay and is held in place by a few bolts. The installation process typically involves disconnecting the battery, unplugging the electrical connectors from the old module, swapping the unit, and reconnecting everything. It is a straightforward process for someone with basic mechanical skills. However, we always recommend consulting a service manual for your specific vehicle.
How do I find my vehicle’s VIN?
Your VIN (Vehicle Identification Number) 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 check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part will resolve the issue. It’s crucial to have your vehicle properly diagnosed to ensure the ECM is the root cause of the problem, as other failing sensors or components can also trigger a check engine light.
