Bosch’s Mastertech VCI (M-VCI) now provides OEM level diagnostics for GM vehicles by supporting GM’s Tech2Win application. Tech2Win is OEM GM diagnostics software, which is coupled with the MDI, or Multiple Diagnostic Interface. The MDI is used by GM dealerships.
Tech2Win provides a virtual environment that allows General Motors Tech 2 diagnostic software to run on a PC. By obtaining a General Motors TIS subscription for Tech2Win and installing the application, a technician can perform OEM diagnostic functions for powertrain, chassis, and body systems on Cadillac, Buick, GMC, Oldsmobile, Pontiac, Saturn, Chevrolet, and Hummer vehicles.
The software’s diagnostic features and reporting capabilities include reading and clearing diagnostic trouble codes, viewing data parameters, operating output controls, and executing system tests.
