Frequently Asked Questions
Do I need to do any programming myself?
No. This ECM arrives fully programmed to your vehicle’s VIN with the latest GM updates. In most cases, it is a plug-and-play installation. Some vehicles may require a simple security relearn procedure (often called a key relearn), which can typically be done without any special tools. Instructions are widely available online for this process.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). You can also add it as a note during the checkout process. We cannot ship your part until we have this information to program the module correctly.
Is this the correct ECM for my vehicle?
This module fits a wide range of 2007 GM vehicles as listed in the compatibility chart. Please verify that your vehicle’s make, model, and engine option are on the list. Matching one of the compatible part numbers (12589297, 12597121, 12603892, 19210738) is the best way to ensure a perfect match.
What is a CASE Relearn and will I need one?
A Crankshaft Variation Relearn (CASE Relearn) synchronizes the new ECM with your engine’s crankshaft position sensor. While not always required, it is recommended for optimal performance and to prevent a P1336 trouble code. Many local repair shops can perform this procedure quickly, and some high-end consumer scan tools also have this capability.
What if my original part number is not 12597121?
That’s okay. Manufacturers often update part numbers over time. This ECM is a direct, compatible replacement for several part numbers, including 12589297, 12603892, and 19210738. As long as your original part number is on our list, this unit will work perfectly for your vehicle.
