my name is joe and i'm a new member. I'm looking for some help with a new toy I just recently bought. It is a gm tech 2 scanner and i need some help with how to use it. I'm familar with some of the smaller scan tools but the tech 2 is far more in depth than what i have been using. any help would be greatly appreciated. if i can be of any help to anyone just let me know. thanks joe
