How to perform GM Tech 2 Selftest


The Tech-2 is the same tester GM Technicians use to diagnose GM vehicles. The Vetronix Tech 2 comes with Authentic GM software and provides support for on-board diagnostics on all GM systems 1999 thru 2013.

Several months ago, I bought a GM tech 2 on CarOBD.fr. And then I heard from my friend that it had better to do a self-test before using it. I am just a green hand, so I turn to ask CarOBD.fr engineer for help.
