Frequently Asked Questions
What information do you need from me?
After you complete your purchase, we will need your vehicle’s 17-digit VIN to program the module. This ensures perfect compatibility and function for your specific car.
Is this part difficult to install?
Because the module comes pre-programmed, the physical installation is typically straightforward. In most cases, you will need to perform a simple security relearn procedure (often called a key relearn), which can be done without special tools and instructions can be easily found online. This syncs the new ECM with your vehicle’s anti-theft system.
Will this fix my check engine light?
This ECM is the definitive fix for a check engine light caused by an internal module failure, indicated by codes such as P0601, P0602, P0603, P0604, P0605, and P0606. If your light is on for another reason (e.g., a bad oxygen sensor), that component will still need to be addressed.
Do I need to send my old computer back?
No. There is no core charge or need to return your old, faulty module. This simplifies the process and gets your car repaired faster.
How does the VIN programming work?
You provide us with your VIN during or after checkout. Our technicians then use professional-grade tools to load the latest, most up-to-date GM software for your specific vehicle onto the module. It is then securely packaged and shipped directly to you, ready for installation.
