What protocols does the MDI support?

(high speed and low speed GMLAN). The GM MDI communicates using all of the existing GM protocols, the same as the Tech 2:
- Class 2
- KWP2000

The Future of the Tech 2
The Tech 2 remains an essential tool through at least the 2010 model year. The GM MDI will not support past models when its diagnostic capabilities are introduced. And, the Tech2 will continue to be needed to diagnose all vehicles fromprevious model years. Remote programming with the Tech 2 will continue to be supported for use on all 2007 and previous vehicles.Additional information will be supplied in future. 

The GM MDI will be required to perform diagnostics on selected NAO vehicles for model year 2009. Diagnostic software is scheduled to be released for the GM MDI during the fourth quarter of 2008.
