Description
MDI The Multiple Diagnostic Interface (MDI) is GM’s ® new interface for wireless J2534 reprogramming. It is a compact communication module that manages the transfer of data between a vehicle’s on-board ECU network and a PC. There are three methods for connecting the MDI to a laptop or PC for service programming and diagnostics: using the USB cable; using the Ethernet cable; or wirelessly.
The MDI provides significant hardware upgrades over the Tech 2 making it much faster at diagnostic. It is also required for certain 2010 and newer GM ® vehicles including the Chevrolet ® Camaro. Each year, GM ® adds to the list of vehicles which require the MDI for reprogramming and diagnostics. The MDI also provides full coverage for all vehicles supported by the Tech 2.
