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:

5. Pls connect the USB cable to PC ( do not need to connect to the Car OBD at this time), the first time connect USB to PC, the USB drive will be detected on the lower right corner, then choose automatic install, click next to finish.
6. when USB drive installation finish, on your PC device manager ,you will find a “MDI USB Device(COM...” on Port place. (Picture 12) , if not then pls find the drive on MDI folder on the CD and install, if still not successful, then pls check if the PC operation is correct or not.
7. open “GM MDI Menager” on the desk to do connection test (if the USB was correct installed, the red “X” on the dialogue will disappear, if the red “X” still on, then pls repeat steap 6
8: finish the installation above, pls connect your PC with internet. ( do not connect to the car OBD ) open this website and activate lease.
http://tis2web.eicp.net:9080/tis2web/after you open this web. Write any user’s name and click ok. All choose OK /continue ( picture 15-17)
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)
GM MDI Package List:
1.GM MDI main unit
2.GM MDI DLC cable
3.GM MDI USB cable
4.GM MDI DVD software
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.)
