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

GM MDI 2 Multiple Diagnostic Interface with Wifi Card

GM MDI 2 Description: 


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

The newest pc-based GM Multiple Diagnostic Interface (MDI 2) offers increased processing power, security, and faster programming speeds on Global A and future
Global B vehicles.

The MDI 2 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).

GM MDI 2 Features:

● Uses a new, more secure Type B connector and Ground Offset Failure protection. A wired connection is recommended for longer programming events.
● The MDI 2 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 MDI 2.

MDI 2 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, FOR GM Global Diagnostics System (GDS), SPS and MDI Manager Software
Allows for GDS diagnostic
FOR 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)
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

What protocols does the MDI 2 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 GM Tech2:
- 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 vehicle
