GODIAG GT106 Heavy Duty Truck 24v to 12v Converter
Godiag GT106 Description:
Godiag GT106 heavy truck power module converter can convert heavy truck diagnostic interface from 24v to 12v, used for X431 easydiag 3.0, easydiag 2.0, Golo Carcare 3, ICARSCAN golo technician box, ThinkCar, Thinkcar2, Thinkcar pro, Thinkdiag, Thinkdiag mini, Thinkdriver obd2 diagnostic Bluetooth head for truck diagnosis. Godiag GT106 supports any device as long as the truck software can be added to it.
It helps to convert the truck's 24v K-Line communication protocol to 12v K-Line so that the launch vehicle equipment can be used, and the launch 12v diagnostic head will not be burned.
Godiag GT106 Overview:

① OBD2 male—used to connect to the 24V truck OBD2 diagnostic interface.
② Display input and output voltage.
③ Pow power indicator J1939 (PIN12), CANH/J1939 (PIN6), J1708 K-line (PIN7) signal communication indicator. Used to determine whether a device or vehicle is communicating.
④ Display input and output voltage function switch buttons.
⑤ OBD2 female—used to connect diagnostic equipment.
⑥ DC power input interface.
Godiag GT106 Functions:
1. Convert the truck diagnostic interface 24V into 12.5V: Convert the 24V voltage of the diagnostic interface of heavy trucks, light trucks, pickup trucks, etc. to 12 V voltage that can be used by the diagnostic equipment.
2. Convert 24V truck K-Line signal to 12V K-Line signal.

3. Communication indication function: When J1939 CANH (PIN12), CANH/J1939 (PIN6), and J1708 K-line (PIN7) have signal communication such as diagnostic programming, the corresponding indicator light will light up or flash. It can display the current status of communication between the diagnostic equipment and the vehicle.

If you do not connect the car and only connect the diagnostic equipment for the software communication signal test, you can judge whether the communication of the diagnostic equipment is normal.

4. Input voltage display function: The display voltage function displays the currently connected vehicle OBD2 diagnostic interface voltage of 24V when the function switch button is popped up. It can be used to monitor the current vehicle diagnostic interface voltage. If the voltage is found to be abnormal, the operation of the vehicle can be stopped.

5. Output voltage display function: When the function switch button is pressed down, the voltage display shows that the voltage of the OBD2 diagnostic output interface after the current conversion is 12.5V. It can be used for equipment self-test before use to ensure that the conversion voltage is normal, which can better protect the 12V diagnostic equipment.

6. DC power interface input function: The DC power input port can be connected to the vehicle power supply, and can also be connected to the power supply in the office. The power supply must be higher than 13V to output a normal 12.5V.

Godiag GT106 Advantage:
1. GT106 simulates the real voltage after starting the vehicle, and the voltage is 12.5V. The voltage of similar products is 12V, but normally the car voltage is about 12.5V after starting.
2. Enable the diagnostic software to better recognize the ignition voltage of the vehicle. As some car models have requirements for the ignition voltage and when the 12v drops slightly to around 11v, some software with more stringent requirements will alarm or stop the diagnosis.
