Frequently Asked Questions
Do I need to get this ECM programmed?
No. This is the biggest benefit of our service. We program the Engine Control Module to the VIN you provide before we ship it. It arrives at your door ready to be installed, saving you a costly trip to the dealership.
What information do you need from me?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. This is crucial for us to load the correct, vehicle-specific software onto the module.
Is any additional setup required after installation?
In most cases, you will need to perform a security relearn procedure, also known as a Passlock or anti-theft relearn. This procedure syncs the new ECM with your vehicle’s anti-theft system and can typically be done in your driveway with just the ignition key. Instructions are widely available online or in service manuals.
How do I know for sure that my ECM is the problem?
While the symptoms listed above are strong indicators, it’s always best to have a proper diagnosis performed by a qualified mechanic. Common diagnostic trouble codes (DTCs) pointing to internal ECM failure, such as P0601-P0606, are a very reliable sign.
Where is the ECM located on my 2007 Avalanche 1500?
On the 2007 Avalanche 1500 and many other GM trucks and SUVs from this era, the ECM is typically located in the engine bay, on the driver’s side, mounted under the battery tray.
Is this part compatible with other part numbers?
Yes. This module is a direct replacement for several service numbers. It is fully compatible with part numbers 12589297, 12603892, and 19210738. If you have one of these, our 2007 Avalanche 1500 ECM 12597121 is the correct part for your vehicle.
