The GoDiag GT106 Plus is a voltage converter specifically designed to convert the 24V power supply of heavy commercial vehicles into a stable 12V output. This makes it possible to connect 12V diagnostic equipment to the OBD2 port of trucks. The module is equipped with a digital display that shows the current voltage and protocol indicators for communication status.
In addition to voltage conversion, the GT106 Plus offers additional testing capabilities. The device can be used to test both 12V and 24V relays to verify their functionality. Furthermore, it supports the diagnosis and cleaning of fuel injectors for both passenger cars and trucks, for which an external cleaning kit and power cable are required.
Application and functionality:
The GoDiag GT106 Plus serves as an adapter and multifunctional tester for vehicle diagnostics and maintenance.
- Voltage conversion: Converts the 24V OBD2 connection of a truck to a 12V output, allowing standard 12V scan tools and diagnostic equipment to be used safely.
- Relay test: Provides the ability to verify the operation of 12V and 24V vehicle relays by externally controlling and testing them.
- Fuel injector test: Supports testing and cleaning of 12V and 24V fuel injectors in combination with an external power source and cleaning agent.
- Protocol indication: LED indicators show which communication protocol is active between the diagnostic device and the vehicle, such as J1939, K-Line, and CANBUS.
- Voltage display: The built-in digital display shows the real-time voltage of the connected power source.
