The GM MDI offers faster programming speed at a lower cost. Depending on the vehicle architecture, the MDI can be 20%-70% faster than the Tech2.?

The GM MDI allows the user to perform Pass-Thru programming procedures using software running on a laptop or desktop PC.
Any PC can be used.

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

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 users.

Protocols 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 Tech 2: UART/Class 2 /KWP2000 /GMLAN(CAN)
