Frequently Asked Questions
Do I need to do any extra programming after I receive this ECM?
No. This ECM arrives fully programmed to your vehicle’s VIN with the latest GM updates. In most cases, you will only need to perform a simple security relearn procedure, which can typically be done without special tools and takes about 30 minutes. Instructions are readily available online for your specific model.
Where do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. Please double-check the VIN for accuracy to ensure a perfect match.
How do I know if this part will fit my vehicle?
This ECM is a direct fit for the models listed, including the 2017-2019 Chevrolet Sonic, 2017-2018 Silverado/Sierra 2500 (6.0L), and 2017-2018 Buick Encore (1.4L, VIN B).

This simple process allows the components to recognize each other and enables the vehicle to start.
