I am looking for all opinions concerning the Tech 2 scanners that seem to be available out there in cyberspace. I have seen my business shift to a large amount of gm products. I am understanding of the need for a CAN capable tool. Simply put I would like to be able to see (as a basic troubleshooting scenario) what the drivers door module is seeing and doing in a 2009 Silverado. I would like all opinions pro or con. I do not plan on any reprogramming but wish to enhance my diagnostic capabilities.
