The GM MDI is a compact communication module that manages the transfer of data between a vehicles onboard ECU network and a PC.
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.

Includes Data Link Connector Cable (J1962 connector) and Multiple Diagnostic Interface Users Guide on CD?
AAA Batteries Included

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)
