Allows for GDS diagnostic

 

GM Multiple Diagnostic Interface (MDI)

All current and most legacy vehicle protocols: UART , KW2000, CLASS2,GM LAN, etc.

Needed for Global A architechture vehicles

Supports Service Programming System (SPS)

Passthrough progrmming on past model and Global A vehicles

Supports PC-Based diagnostics with rollout of the Global Diagnositc System (GDS) application

Includes Flight Recorder Mode

 

New Diagnostic Application Software required for Global A Vehicles

Global Diagnostic System (GDS)

PC-based software diagnsotics

DTCs, Diagnostics, Data Display & Visualization, Device Controls, Special Tests,Flight Recorder management, etc.

GDS is software which runs on a specific PC. Updates received via TIS2Web.
