Used in most GM vehicles from 2006 onward. This OBDII protocol provides high-speed communication with the engine, transmission and numerous other control modules throughout the vehicle. - GMLAN Single-Wire CAN Bus
Found in most GM vehicles from 2006 onward. Typically used for infotainment, HVAC, instrument clusters, parking assist and other body-related modules. - J1850-VPW
Commonly found in GM vehicles built between 1996 and 2006. Unlike generic scan tools, the OBDX Pro GT supports 4× high-speed mode, allowing for faster and more reliable communication during programming operations on vehicles using the J1850-VPW protocol. - ALDL
Supports the Holden ALDL protocol through Terminal 9 of the OBDII connector.
The OBDX Pro GT provides flexible connectivity options designed to work across a wide range of platforms:
