GM MDI2 OEM Factory Interface and J2534 Device


The GM MDI 2 (Multiple Diagnostic Interface 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).



  • 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.
