1.Hardware design
- HD-II Module
As the 2nd generation of heavy-duty module, it mainly functions as a VCI device for accessing vehicle data.
LED indicators: It is defined as follows(from left to right):
- Power Indicator: It lights up when it is powered
- Communication LED of Tablet: It illuminates when the module is communicating with the
- Communication LED of Vehicle: It lights up once the module is connected to a vehicle’s
- Communication LED of PC
- Data I/O LED
2.Data I/O port
- Communication Port of PC
- Diagnostic Socket: To connect the included diagnostic
- DC-IN power jack: To connect the power
B.HD-III Module
As the 3rd generation of heavy-duty module, it works as a vehicle communication interface device, which is used to read the vehicle data and then send it to the X-431 V+ via wireless BT/WLAN communication. The LED indicators enable you to easily identify the working status of the module.
- LED indicators: It is defined as follows:
- DC-IN power jack: For connecting the power
- Diagnostic socket: For connecting the diagnostic
- Vehicle: While communicating with the vehicle, the indicator lights up and flashes. Otherwise, it will not

A.HD-II module:
B.HD-III module:
Besides the BT communication, the HD-III VCI module comes loaded with a built-in WLAN module, which can work as a wireless hotspot or a network adaptor
4.Vehicle connection
(For Commercial Vehicle Version)
The method used to connect the VCI module to a vehicle’s DLC depends on the vehicle’s configuration as follows:
1.OBD II Vehicle Connection: Plug one end of the diagnostic cable into the vehicle’s DLC, and the other end into the diagnostic socket of the VCI module, and then tighten the captive
2.Non-OBD II Vehicle Connection: For vehicles with non-OBD II diagnostic socket, a non-16pin connector (adaptor cable) is
A. Using HD-II module
For trucks equipped with non-OBD II 16 PIN diagnostic sockets, choose any one of the following to proceed:
B. Using HD-III module
Notes:
For commercial vehicles, refer to the above connection method to proceed.
For passenger vehicles, replace the “Non-16pin connector” with “OBD I adaptor” + “non-16pin connector (for passenger vehicles)”. Other connections shall also apply.
