MDI Description:

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 ).

Can be Used for SPS programming on existing and future SGM vehicles

Required for diagnostics on new SGM Global A Electrical Architecture Vehicles

G-M Global Diagnostics System (GDS), SPS and MDI Manager Software

Allows for GDS diagnostic

G-M Multiple Diagnostic Interface (MDI)

All current and most legacy vehicle protocols: UART, KW2000, CLASS2, G-M LAN, etc.

Needed for Global A architechture vehicles

Supports Service Programming System (SPS)

Passthrough progrmming on past model and Global A vehicles

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.

Multiple display options. More space for diagnsotics. Session management for multiple us.

The Future of the Tech 2

The Tech 2 remains an essential tool through at least the 2010 model year. The G-M 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 new G-M 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 G-M 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 G-M MDI will be required to perform diagnostics on selected NAO vehicles for model year 2009. Diagnostic software is scheduled to be released for the G-M MDI during the fourth quarter of 2008.

Regulations require programming procedures to be compliant with SAE Recommended Practice J2534. The G-M SPS is compliant with SAE Recommended Practice J2534, and the G-M MDI is compliant with the portions of SAE J2534 that are applicable for G-M vehicles.

What protocols does the G-M MDI support?

For immediate use — At present, vehicles have two buses on the 16 pin connector

(high speed and low speed GMLAN). The G-M MDI communicates using all of the existing G-M protocols, the same as the Tech 2:


– Class 2

– KWP2000


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.)
