For auto repair shops specializing in GM vehicles, the right scan tool is essential. GM cars need specific tools for deep system access. This article covers key GM scan tools: GM MDI and Tech-2, helping you choose the best one.
GM MDI & GDS2: Modern GM Diagnostics
The GM MDI is the factory tool for most GM cars from 2010 onward. With Global Diagnostic System 2 (GDS2), MDI offers dealer-level diagnostics for GM’s Global Architecture (Global A) vehicles. This includes Buick LaCrosse, Cadillac SRX, Chevy Camaro, Equinox, Volt, Cruze, GMC Terrain, Buick Regal (2010-2013), and almost all 2014+ GM models. MDI/GDS2 allows full scanning, DTC reading, live data graphing, and bi-directional controls across powertrain, body, chassis, and network systems.
Tech-2 & Emulator: For Older & Some Newer GM Cars
For older GM vehicles and specific newer model tasks, GM Tech-2 remains valuable. While MDI/GDS2 is primary for new cars, Tech-2 or ‘Tech-2 Emulator’ (with MDI) offers OEM-level function for some 2010-2013 and older GM models. Tech-2 Emulator expands MDI’s vehicle coverage.
