As for as I am concerned , the GM Tech2 scanner is a really amazing tool that has highest performance and most convenience for us . You can always use this tool to deal with problems and do what you want . There are some reason to show why the tool is amazing .
General Motors Repair Technicians use a hand-held computer called the “Tech 2″ to diagnose and tune modern vehicles. It is called the Tech 2 because there was originally a Tech 1, and this is the update.
The Tech 2 is like a scan tool on steroids, with some additional tuning options thrown in. As a scanning tool, the Tech 2 excels. While an off the shelf scanner will read the Engine Diagnostic Trouble Codes (DTCs), the GM Tech 2 Scanner will read and report information from all the car’s systems, including ABS, Air Conditioning, Air Bags, and other systems a standard scanner will not read. For example, in my CTS Seat experiment after the seat was replaced the Tech 2 must be used to run a Passenger Presence System relearn. There is no other way to run this tuning step other than with the Tech 2. Similarly some vehicle customizations or radio resets require a Tech 2 to perform.
Candi of Professional Diagnostic Tools GM Tech2 Description: An industry change in protocol from OBD II to Controller Area Network (CAN) has begun. In order to perform diagnosis on a vehicle that uses the CAN interface, you will need the Tech 2 Flash and a CAN diagnostic interface module.
