Get Your Duramax Back on the Job, Fast.
When your Silverado, Sierra, Express, or Savana van is down, every hour costs you money. A faulty Engine Control Module (ECM) can bring your entire operation to a halt, causing frustrating no-start conditions, poor engine performance, or a dashboard full of warning lights. This isn’t just an inconvenience; it’s a threat to your livelihood. We understand that you need a reliable, straightforward solution that gets your workhorse back on the road without expensive trips to the dealership or complicated programming procedures.

Expert Insight: The Critical Role of Correct Programming
From over 20 years of hands-on diagnostics, I can tell you that installing a non-programmed or incorrectly programmed ECM into a Duramax is a recipe for disaster. These modules are the brain of the entire powertrain, controlling everything from the high-pressure fuel injectors to the transmission shift points. Using a generic module from a salvage yard will, at best, result in a no-start condition. At worst, it can cause damage to other electronic components. Our process of flashing this programmed 12606126 ECM with your specific VIN ensures that all factory parameters, security information (anti-theft), and operational software are a perfect match, just as if it came directly from the factory assembly line.
Frequently Asked Questions
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is a critical part of the order.
Will I need to do any additional programming after installation?
In most cases, no. This module is designed to be plug-and-play. Once installed, the engine should start and run correctly. Some vehicles may require a simple security relearn procedure, which can typically be done without special tools and instructions can be readily found online.
Is this a brand new part?
This is a high-quality, tested, and verified replacement part that has been professionally prepared and programmed to meet or exceed original factory specifications. It provides a reliable and cost-effective solution to a new part from a dealer.
What if my original part number is not on your list?
The part numbers listed (19260753, 12588335, etc.) are the most common, but there may be others. As long as your vehicle is a 2006-2007 GM truck or van with the LLY Duramax diesel engine, this programmed 12606126 ECM is the correct module for your application.
Where is the ECM located on my truck?
On the 2006-2007 Classic Silverado and Sierra pickups, the ECM is located on the driver’s side, in the engine compartment, under the battery tray. On the Express and Savana vans, it is located in the left-hand rear of the engine compartment.
