Frequently Asked Questions
How does the programming process work?
It’s simple. After you complete your purchase, you’ll need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). Our technicians will then use certified equipment to load the correct GM-approved software and calibration files for your specific vehicle onto the ECM before it ships. This makes it ready for installation right out of the box.
Where can I find my VIN?
Your VIN can be found in several places: on a metal tag on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
Will I need to have a mechanic install this?
While the installation is often straightforward (disconnecting the battery, unplugging the old unit, and plugging in the new one), the location of the ECM can vary. If you are comfortable working on your vehicle and have basic tools, you may be able to perform the installation yourself. However, we always recommend consulting a repair manual for your specific model or having a qualified mechanic perform the work if you are unsure.
Is any other programming required after installation?
In most cases, no additional programming is needed. However, some vehicles may require a security relearn procedure (often called a CASE relearn or anti-theft relearn) to sync the new ECM with the vehicle’s keys and security system. This procedure can typically be done without special tools and instructions can be found online or in a service manual.
What if I order the wrong part?
Our VIN-matching process is designed to prevent this. By programming the module to the VIN you provide, we ensure compatibility. Please double-check that your vehicle is on the fitment list and that your original module’s service number matches one of the numbers listed in the description.
