Frequently Asked Questions
Do I need to do any additional programming after installation?
No. This ECM comes fully programmed to the VIN you provide at checkout. In most cases, it is a simple plug-and-play installation. On some vehicles, a security relearn procedure may be required, which can be done without special tools and typically takes about 30 minutes. We include instructions for this simple process.
Where is the ECM located on my truck or van?
On 2006-2007 Classic Silverado and Sierra pickups, the ECM is located in the engine bay on the driver’s side, typically under or near the battery tray. On Express and Savana vans, it is located in the LH rear of the engine compartment.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit VIN. We cannot ship your order until we receive this information, as the programming is a critical part of the process.
What part numbers does this ECM replace?
This module is a direct replacement for a range of part numbers, including 19260753, 12588335, 12606126, 12606127, 19260753, 12603623, 12604137, and YNAY. If your original module has one of these numbers, this unit will work for your vehicle.
Will this work if my truck has aftermarket modifications?
This ECM is programmed with standard GM factory software. It is designed for vehicles with stock or near-stock configurations. It is not intended for vehicles with significant performance modifications that require specialized engine calibration.
Is this the same as a FICM?
No. This is the Engine Control Module (ECM), which is the main computer for the engine. The FICM, or Fuel Injection Control Module, is a separate module on Duramax engines that controls the fuel injectors. The ECM sends commands to the FICM. This listing is for the main 2006-2007 Duramax ECM only.
