Global Diagnostic System (GDS2)MDI (Multiple Diagnostic Interface)


The GM MDI is the Global Diagnostic tool for future vehicles starting with Global A vehicles. It’s a compact communication module that manages the transfer of data between a vehicle’s onboard ECU network with an auxiliary CAN bus.

The GM MDI was introduced in the fall of 2007 for Pass-Thru programming and offers faster programming speed using J2534. Depending on vehicle architecture, the MDI can communicate 20% to 70% faster than the Tech 2. It can be used to perform Pass-Thru programming on all vehicles built since 1996 and into the future. Please note that there are other J2534 VCIs (vehicle communication interface) that will perform MDI functions utilizing GDS2 software.

Servicing the next generation Global A vehicles requires the diagnostic software, GDS2 (Global Diagnostic System 2) running on a local PC device while the MDI is connected to the vehicle.

The MDI connects to the vehicle via the J1962 connector using a DLC cable. Connection between the MDI and the PC can be accomplished via standalone (USB) or through (CAT5, or Wireless) networks.
