Frequently Asked Questions
How does the programming process work?
It’s simple. After you complete your purchase, you provide us with your vehicle’s 17-digit VIN. Our technicians use this number to access the latest official GM software for your specific make, model, and options. We then flash this software onto the module before shipping it to you.
Do I need to do anything after installation?
In most cases, this is a plug-and-play installation. However, some vehicles may require a security relearn procedure (often called a CASE relearn or anti-theft relearn), which can typically be done without special tools. Instructions are widely available online for specific models, and it’s a simple key-cycle process.
How do I find my original part number?
Your original part number is printed on a sticker on the ECM itself. While this module replaces multiple part numbers, confirming your original number is always a good practice. You can find the ECM’s location in your vehicle’s service manual; it’s often in the engine compartment or under the dash.
What if I provide the wrong VIN?
The VIN is critical for correct programming. Please double-check the VIN from your driver’s side door jamb sticker or your vehicle’s registration/insurance card before sending it. An incorrect VIN will result in a module that will not work with your vehicle.
Is this a brand new part?
This is a high-quality, inspected, and tested replacement part that has been verified to meet or exceed original equipment specifications. It is not a new part from the original manufacturer.
