GM owners can buy a GM edition scanner or an all-makes tool. GM editions such as the Launch Creader Elite X500 for GM and the Foxwell NT710 and NT510 Pro focus on Chevrolet, GMC, Buick and Cadillac, with full-system diagnosis, active tests and GM jobs like crankshaft relearn. All-makes tools cost more but also cover your other cars. One detail matters for newer trucks and SUVs: several listings here state CAN FD support for newer GM vehicles, and some name 2019 and later. If your GM is recent, check that a tool's listing states CAN FD before you buy. The GM edition listings in this guide do not mention CAN FD, so confirm coverage for your model year with the seller. This guide compares eight tools using only what each Amazon listing states about GM coverage, bidirectional control, reset services, CAN FD and updates.
