GODIAG GT106 Plus 24V to 12V Heavy Duty Truck Adapter replaced GODIAG GT106. It not only can work with Launch 12V vehicle equipment for HD truck diagnosis, but also supports fuel injector cleaning and relay test for cars and trucks. It’s a good assistant tool for truck/car maintenance technicians, and DIY maintenance personnel.
GODIAG GT106 Plus Adapter Hardware Display:
(1) OBD2 male—used to connect to the 24V truck OBD2 diagnostic interface.
(2) Display input and output voltage.
(3) Pow-- power indicator CANH/J1939 (PIN6), J1708 (PIN12), K-line (PIN7) signal
communication indicator. Used to determine whether a device or vehicle is communicating.
(4) Display input and output voltage function switch button.
(5) OBD2 female—used to connect diagnostic equipment.
(6) DC power input interface.
(7) Injector/relay test output interface.
How to use the functions of GODIAG GT106 Plus?
1.Convert the truck diagnostic interface 24V into 12.5V:
Convert the 24V power of the truck diagnostic interface into DC12.5V and supply it to the 12V diagnostic equipment with truck diagnostic software, so as to protect the 12V diagnostic equipment. 12.5V is to simulate the voltage after the vehicle is started, which can ensure that the 12V diagnostic equipment software can normally recognize the voltage after the vehicle is started. 【Some diagnostic software will alarm or stop the diagnosis if it recognizes that the starting voltage of the vehicle is lower than normal.】
2.Convert 24V truck K-Line signal to 12V K-Line signal:
The 12V diagnostic equipment 7PIN K-Line communication will be burned by the 24V K-line signal of the truck without step-down conversion. GODIAG GT106 PLUS 24V TO 12V OBD2 Scanner For Heavy Duty Truck Adapter can convert the truck's 24V K-line voltage signal into 12V K-line signal in order to protect the 12V diagnostic equipment 7PIN K-Line communication from being burned by 24V.
3.Communication indication function:
When CANH/J1939 (PIN6), J1708 (PIN12), K-line (PIN7) has 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 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 normal 12.5V.
7.12V relay, fuel injector test function
Relay or injector test steps: Connect 12V DC power from the POW IN port. Connect the fuel injector or relay according to the connection diagram, after connecting, connect to the IR TEST OUT interface. If the relay or fuel injector is activated, it can be judged that the tested accessory is normal.
(Note: When working, the POW IN interface needs to be connected to a DC 12V 3A power supply. Please refer to the connection diagram for how to connect the car battery.
Relay or injector test connection line, be sure to connect the line we provide with the fuse box. Since the power of the fuel injector is large, the diagnostic interface is not suitable for testing high-power relay/ fuel injectors, so this device shields the diagnostic interface for relay/ fuel injector testing.)
8.24V relay fuel injector test function
24V relay or injector test steps: Connect 24V DC power from the POW IN port.
Connect the fuel injector or relay according to the connection diagram. After connecting, connect to the IR TEST OUT interface. If the relay or fuel injector is activated, it can be judged that the tested accessory is normal.
(Note: When working, the POW IN interface needs to be connected to a DC 24V 8A power supply. Please refer to the connection diagram for how to connect the truck battery. Relay or injector test connection line, be sure to connect the line we provide with the fuse box. Since the truck fuel injector has high power, the diagnostic interface is not suitable for testing high-power relay/ fuel injectors, so this device shields the diagnostic interface for relay/fuel injector testing.)
