you can use a tech2 on your xx-14 suv's in 2014 gm switched over to GDS2 but I have read you can still use the tech2 for 2014 suv's but I haven't tried it on a 14 yet.Ok your talking foreign language to me!! Lol, but I’m interested in seeing how it works. To whom do I contact? Having GM cars/trucks from 2007 to 2017 would be awesome to be able to do stuff like this.
you can get a little electronic obd device online called a vx diag nano, it runs via usb on a windows laptop or tablet and it will give you tech2win (software based tool) and GDS2 for the 14+
the vx diag runs about $100-125 works on 07-14, and 14-current with gds2
~versus~
a clone tech2 (tool) runs about $300
a gds2 based (tool) runs $1200+
~versus~
a trip to the dealer for a diagnostic is $100 a pop
