GPT, DOIP and ENET Support

GT100 PLUS GPT supports GPT connection methods for compatible ECU read/write operations and can be used with external tools such as ECU programmers and flash tools. It also supports DOIP / ENET communication for supported vehicles and diagnostic/programming platforms.

DOIP / ENET functions depend on the external diagnostic or programming software used with the device. No diagnostic software is included with this breakout box.

OBDII Breakout Box and Bench ECU Connection

The device allows technicians to connect to ECU modules on the bench, monitor communication lines and check power supply conditions before diagnostic or programming work. It is useful for reducing the risk of wiring mistakes and for quickly identifying abnormal voltage or current conditions.

24V to 12V Voltage Conversion

GODIAG GT100 PLUS GPT can convert a 24V diagnostic interface signal from trucks and commercial vehicles to a 12V level suitable for standard diagnostic equipment. This makes it useful for workshops working with both passenger cars and heavier vehicle applications.

Voltage and Current Monitoring

The built-in display shows real-time voltage and current values. This helps technicians check whether the power supply is normal and identify possible wiring errors, short circuits or damaged ECU modules before continuing with diagnostics or programming.
