Frequently Asked Questions
How does the VIN programming process work?
It’s simple. After you place your order, you provide us with your vehicle’s 17-digit VIN. Our technicians then use that VIN to load the exact, correct GM factory software and calibrations onto the ECM. This ensures it works seamlessly with your car’s specific options and systems right out of the box.
Is this a difficult part to install?
The physical installation is typically straightforward, as it’s a direct-fit part. However, like most GM vehicles of this era, a security relearn procedure (often called a CASE relearn or anti-theft relearn) will need to be performed after installation. This can be done with a capable scan tool or by following a specific key-on/key-off procedure. We recommend consulting a service manual or a qualified technician.
How can I be sure my original ECM is the problem?
While the symptoms listed above are strong indicators, a full diagnosis by a professional technician is the best way to be 100% certain. They can check for communication errors, verify power and ground to the module, and rule out other potential issues like wiring or sensor faults before you purchase a new 2009 Corvette ECM 12639300.
My original part number is different. Will this still work?
Yes. This ECM, service number 12639300, is the updated, interchangeable replacement for a range of earlier part numbers, including 12636659, 12628993, 12628911, and others listed in the fitment guide. As long as your vehicle is on the compatibility list, this module will function correctly once programmed to your VIN.
What does the one-year replacement warranty cover?
Our one-year replacement warranty covers the module itself against any functional defects. If the unit fails within one year of the purchase date, we will provide a replacement unit. The warranty is for the part itself and does not cover labor, diagnostics, or shipping costs.
