The newest pc-based GM Multiple Diagnostic Interface (MDI II) 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.
