1. New GM MDI Multiple Diagnostic Interface with
WIFI
GM MDI is a new GM Diagnostic tool.
It does not only work for the new gm car,but also for the old kind of car.It can
test Chinese and American GM cars from 1990-2012.
GM Multiple Diagnostic Interface (MDI) Programming Solution Bundle!
Language:

2. Multiple Diagnostic Interface Descripition:
for 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.
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
GM Multiple Diagnostic Interface (MDI)
All current and most legacy vehicle protocols: UART, KW2000, CLASS2, GM
LAN, etc.

3. Needed for Global A architechture vehicles
Supports Service Programming System (SPS)
Pass through progrmming on past model and Global A vehicles
Supports PC-Based diagnostics with rollout of the Global Diagnostic 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.
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

4. 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/CANDY 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

5. GM vehicles.
Multiple Diagnostic Interface Feature:
1. With opel Global tis global diagnostic system
2. Support offline lease function
3. Support for Opel offline programming function
4. With GDS2 diagnostic system
5. Tech2win diagnostic software support adding latest software
6. support programming online
7. support cable communication
8. support wireless communication
9. support original factory latest software
10. With European for Chevrolet Global tis, Supports European for Chevrolet
offline programming
11. All Chip are new and original
Multiple Diagnostic Interface Spported
protocols:
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:
- UART
- Class 2
- KWP2000
- 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.
when you test after 2010 year gm car ,you can use gm gds2 software:

7. When you want to test before 2010 year GM car, you can use the techwin
software to test it,run fast and stable:

9. GM MDI installation
PC specification require: Full installation version WIN XP3, pls install all the
systerm patch (picture 0)
