Compared to the older version of the GT100 breakout box, the new GT100 Plus includes the following updates:
1. Supports 24V to 12V voltage conversion function.
Convert the 24v voltage of the diagnostic interface of heavy trucks, light trucks, pickups, etc. into 12v voltage that can be used by diagnostic equipment.
2.DOIP Ethernet diagnostics
3. GPT connection method for ECU reading and writing (with PCMFlash, KESS2 etc)
Support GPT to read and write data without disassembling the ECU.
Supports OBD2 BENCH [CAN bus & K-Line]
Supports GPT BOOT CNF1
4. Airbag connection, supporting 100K CAN BUS communication, compatible with godiag BMW CAS1/CAS2 and CAS2/CAS3 test platforms.
