Why GM Tech 2 Scanner Is Necessary
I find the GM Tech 2 scanner necessary because it gives me direct access to the deeper diagnostic functions of GM vehicles that a basic code reader simply cannot reach.

My Buying Guides on Gm Tech 2 Scanner
What I Look for in a GM Tech 2 Scanner
When I shop for a GM Tech 2 scanner, I first focus on compatibility. I want to make sure it works with the specific GM vehicles I plan to diagnose, including older models if needed. I also check whether it supports the systems I care about most, such as engine, transmission, ABS, airbag, and body control modules.
Why I Prefer the GM Tech 2 Scanner
From my experience, the GM Tech 2 scanner is valuable because it gives me access to deep diagnostic functions that basic code readers cannot. I like that it can read and clear trouble codes, view live data, perform bi-directional tests, and help with special functions like key programming and module setup on supported vehicles.
