4.3.3 Vehicle connection

The method used to connect the VCI module to a vehicle's DLC depends on the
vehicle's configuration as follows:
A vehicle equipped with an OBD II management system supplies both
communication and 12V power through a standardized DLC.
A vehicle not equipped with an OBD II management system supplies
communication through a DLC connection, and in some cases supplies 12V
power through the cigarette lighter receptacle or a connection to the vehicle
battery.
Follow the steps mentioned below to connect OBD II vehicle:
1. Locate vehicle's DLC socket.
2. Plug the VCI module into the vehicle's DLC socket (It is suggested to use the
OBD II extension cable to connect the VCI module and DLC socket.).
3. Choose one of the two ways to obtain power from:
A. Power adaptor: Connect one end of the included power adaptor to DC IN
port of X-431 PRO MINI tablet, and the other end to AC outlet.
B. Internal battery pack
For non-OBDII vehicle, proceed as follows:
1. Locate vehicle's DLC socket.
2. Select the corresponding non-16pin connector.
3. Plug the non-16pin end of the connector into the DLC socket, then connect
the other end to the OBD I adaptor, and then tighten the captive screws.
4. Connect the other end of the adaptor to the included VCI module.
