MDI and GDS Background
MDI is an interface between the vehicle DLC and a PC (by wired USB, wired Ethernet, wireless Ethernet ) and TIS2web.
Can be Used for SPS programming on existing and future SGM vehicles
Required for diagnostics on new SGM Global A Electrical Architecture Vehicles
Used with TIS2Web, GM Global Diagnostics System (GDS), SPS and MDI Manager Software
Allows for GDS diagnostic
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.
HOW WILL THE GM MDI BE USED?
The new GM MDI can be used only in the Pass-Thru method. This means you can use it as your programming tool, while your Tech 2/CANdi remains available for diagnostics and other duties.
The GM MDI is initially being introduced with Pass-Thru programming capabilities only. It can be used to perform Pass-Thru programming on all vehicles built since 1996 and will support all vehicles into the 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.
Regulations require programming procedures to be compliant with SAE Recommended Practice J2534. The GM SPS is compliant with SAE Recommended Practice J2534, and the GM MDI is compliant with the portions of SAE J2534 that are applicable for GM vehicles.
When you test after 2010 year gm car, you can use gm gds2 software:
When you want to test before 2010 year GM car, you can use the techwin software to test it, run fast and stable:

9: in the main interface, please click “Global Diagnostic System2(GDS 2)” icon, and click GDS2 to run, at that time, software will update lease automatic .after update finish, software GDS2 (Launch GDS2 on the desk) will open automatically , choose the language and back to the main interface.
Bottom left will have a lease expire time. Be attention, it need only your PC systerm time, don’t change. Afterward we don’t need internet to update lease, so if there have any remind indicate new update available,please do not click update (picture 18-21
1: finish update lease step, connect with Car OBD, click diagnostic icon on the interface. Choose brand and click “input” on lower right corner, car information will be read automatically, or you can choose manual input VIN
2:choose test what you want, like module diagnostic—engine control modual—identifying information ( picture22-27)
What protocols does the GM MDI support?
For immediate use — At present, vehicles have two buses on the 16 pin connector
(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
- GMLAN (CAN)
Beginning with the 2008 model year vehicles, Pass-Thru will be the only programming method available. (Remote will continue to be available for previous vehicles.)
