The latest PC-based GM Multiple Diagnostic Interface (MDI II) delivers enhanced processing power, security, and quicker programming speeds for Global A and upcoming Global B vehicles. Supporting diagnostic applications like GDS 2, Data Bus Diagnostic Tool, and Tech2Win, as well as Pass-Thru programming via TIS2Web–SPS, it replaces the original MDI for Pass-Thru programming on current GM models since 2007. Backward compatible, it handles Pass-Thru programming for vehicles built since 1996.

Key Features:

  • Features a more secure Type B connector and Ground Offset Failure protection; wired connection recommended for longer programming events.
  • Powered from the vehicle battery via the DLC Cable, with USB powering for firmware updates using a PC.
  • Utilizes USB 2.0 for faster firmware downloads, eliminating the need for a separate AC power supply.
  • Includes a longer DLC cable that connects at the top for enhanced usability, and only links to the MDI 2.

Kit Components:

  • MDI 2 Unit
  • SAE J1962 DLC Cable
  • 10-ft. USB A to USB B Cable
