General Motors Global Electrical Architecture (Global A) and Global Diagnostic Hardware &Software
Global Diagnostic System DGS& Mutiple diagnostic Interface MDI

MDI and GDS Background
MDI is an interface between the vehicle DLC and a PC (by wired USB, wired Ethernet, wireless Ethernet ) and TIS2web.
Required for diagnostics on new SGM Global A Electrical Architecture Vehicles
Used with GM Global Diagnostics System (GDS), SPS and MDI Manager Software
Allows for GDS diagnostic

Software Display:

GM Multiple Diagnostic Interface (MDI)
All current and most legacy vehicle protocols: UART, KW2000, CLASS2, GM LAN, etc.
Needed for Global A architechture vehicles
Supports Service Programming System (SPS)
Supports PC-Based diagnostics with rollout of the Global Diagnositc System (GDS) application
Includes Flight Recorder Mode
New Diagnostic Application Software required for Global A Vehicles
Global Diagnostic System (GDS)
PC-based software diagnsotics
DTCs, Diagnostics, Data Display & Visualization, Device Controls, Special Tests, Flight Recorder management, etc.
GDS is software which runs on a specific PC. Updates received via TIS2Web.
Multiple display options. More space for diagnsotics. Session management for multiple us.

What protocols does the MDI for GM Support?
For immediate use — At present, vehicles have two buses on the 16 pin connector
(high speed and low speed GMLAN). The GM MDI scan tool communicates using all of the existing GM protocols, the same as the Tech 2:
– Class 2
– KWP2000

The Future of the GM 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 at during the fourth quarter of 2008.
