GM MDI2 GDS2

Software GDS2 Tech2Win V2020.3 Description:

The Multiple Diagnostic Interface 2 (MDI2) is used by professional technicians as an aid in diagnosing and repairing automotive electrical and electronic systems. It is designed to connect the vehicle to a host PC computer application, which then functions through the device for data transfer and Electronic Control Unit (ECU) reprogramming.

The newest pc-based -G* M Multiple Diagnostic Interface (MDI2) offers increased processing power, security, and faster programming speeds on Global A and future
Global B vehicles.

The MDI2 supports diagnostic applications: GDS 2, Data Bus Diagnostic Tool, and Tech2Win. It also supports Pass-Thru programming applications: TIS2Web–SPS. It replaces the first generation MDI, introduced in 2007, for Pass-Thru programming on current GM models. The MDI 2 is backward compatible, so it can be used to perform Pass-Thru programming on all vehicles built since 1996 by means of the J1962 connector using a DLC cable. Connection between the MDI 2 and the PC can be accomplished via standalone (USB) and the dealership network (CAT5).

Support Languages: English, Spanish, Latin, French, Italian, German, Portuguese, Russian, Japanese, Korean, Vietnamese

Features:

–Uses a new, more secure Type B connector and Ground Offset Failure protection. A wired connection is recommended for longer programming events.
— It is powered from the vehicle battery via the DLC Cable. It may also be powered over USB to perform firmware updates only using a PC.
— Uses USB 2.0 for faster firmware downloads instead of a separate AC power supply.
— The DLC cable is twice as long as the previous cable and connects at the top, making it easier to use. The cable only connects to the device (GM MDI2 GDS2)

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 SG-M vehicles

Required for diagnostics on new SG-M Global A Electrical Architecture Vehicles

Used with TIS2Web, For G-M Global Diagnostics System (GDS), SPS and MDI Manager Software

Allows for GDS diagnostic

Multiple Diagnostic Interface MDI for GM

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

Needed for Global A architechture vehicles

Supports Service Programming System (S-PS)

Passthrough progrmming on past model and Global A vehicles

Supports PC-Based diagnostics with rollout of the Global Diagnositc System (G-DS) application

Includes Flight Recorder Mode

New Diagnostic Application Software required for Global A Vehicles

Global Diagnostic System (G-DS)

PC-based software diagnsotics

DTCs, Diagnostics, Data Display & Visualization, Device Controls, Special Tests, Flight Recorder management, etc.

GD-S is software which runs on a specific PC. Updates received via TIS2Web.

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

The Future of the Te-ch 2：

The Te-ch 2 remains an essential tool through at least the 2010 model year. The MDI for GM will not support past models

when its diagnostic capabilities are introduced. And, the Te-ch2 will continue to be needed to diagnose all vehicles

fromprevious model years. Remote programming with the Te-ch 2 will continue to be supported for use on all 2007 and

previous vehicles.Additional information will be supplied in future.

HOW WILL THE MDI for GM BE USED? (GM MDI2 GDS2)

The new MDI for GM can be used only in the Pass-Thru method. This means you can use it as your programming tool, while your Te-ch 2 / CA-N-DI remains available for diagnostics and other duties.

The MDI for GM 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 MDI for GM will be required to perform diagnostics on selected NAO vehicles for model year 2009. Diagnostic software is scheduled to be released for the MDI for GM during the fourth quarter of 2008.

Regulations require programming procedures to be compliant with SAE Recommended Practice J2534. The for 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 MDI for GM support?

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

(High speed and low speed G-MLAN) The MDI for GM communicates using all of the existing for G-M protocols, the same as the Tech 2:

– UART

– Class 2

– KWP2000

– For G-MLAN (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.)
