High Quality WIFI GM MDI Tech3 Tech 3 Multiple Diagnostic Interface

GM MDI Multiple GM TECH3 Replace GM Tech 2 Diagnostic Interface For GM Cars till 2018

GM MDI (Multiple Diagnostic Interface) for wireless ECU reprogramming utilizing J2534.
The GM MDI is initially being introduced with Pass-Thruprogramming capabilities only. It can be used to perform Pass-Thru programming on all vehicles built since 1993 and willsupport all vehicles into the future.The GM MDI will be required to perform diagnostics onselected NAO vehicles for model year 2009. Diagnostic soft-ware is scheduled to be released for the GM MDI during thefourth quarter of 2008.

When diagnostics are introduced, the MDI will also get a remote data record capability. This permits recording data duringa road test, similar to the Tech 2 Snap Shot function. A trigger switch connector is provided for this purpose. Regulations require programming procedures to be compliantwith SAE Recommended Practice J2534. The GM SPS is com-pliant with SAE Recommended Practice J2534, and the GMMDI is compliant with the portions of SAE J2534 that areapplicable for GM vehicles.

GM MDI Interface Description

The MDI is used by professional technicians as an aid in diagnosing and repairing automotive electrical and electronic systems. The MDI is designed to connect the vehicle to a TIS 2 Web PC computer application which then functions though the MDI for data transfer and Electronic Control Unit (ECU) reprogramming. See Figure IV-2 for the location of the connectors and indicators (LEDs) on the MDI.

Host Computer Interface

Using the PC application MDI Manager software, you configure the MDI to communicate with a host computer. The MDI is capable of communicating over a USB cable, an ethernet cable (LAN), or wireless (WLAN),PC Connections on the 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.
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 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 GM vehicles.

What protocols does the GM MDI support?

For immediate use â€” 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.)
