What’s a tech2? I could google it but figure I’d ask you anyways lol
It's the scan tool that GM uses to diagnose and work on these trucks with. It can also reprogram modules. GM has moved on to another system, the Tech2s price has come way down now when purchased from overseas and will work on cars from 1996-2013. Search the forum and you'll my threads and others on the subject.
