What’s the difference between HD 2 adapter and HD 3 adapter?

 

1. Hardware design

A. HD-II Module

As the 2^nd 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 3^rd 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
• Power: It illuminates solid red when the module is powered

•  BT: Blue indicates the module is working in wireless BT
  • I/O: It lights up when the module is connected to the diagnostic tool via data cable (Currently disabled and only reserved for subsequent function extension).
  • Wireless: It lights up when the module works as a wireless hotspot or network

• Data I/O port: Currently disabled and only reserved for subsequent function

1. 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.
