Features and Benefits:

• 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.
• Kit Includes Components:
• MDI device
• DLC Cable SAE J1962
• 10-ft. USB A to USB B Cable
• Ethernet Cable
• Two pcs. of D-Link Wireless USB Adapters (Dongles) for wireless connection
• Service:
• Multilingual support hotline for hardware problems and questions
• Exchange process (within the warranty period) when your hardware develops a fault, reducing downtime.
• 2 year supplier warranty


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.
