4.3 Connections

4.3.1 Preparation

1. Make sure that the vehicle battery voltage is 11~36V and the ignition is
turned on.
2. Find the vehicle's DLC location: The DLC (Data Link Connector) is typically a
standard 16 pin connector where diagnostic tools interface with the vehicle's
on-board computer. For commercial vehicles, it is generally located in the
driver's cab.
If the DLC cannot be found, refer to the vehicle's service manual for the
location.

4.3.2 Vehicle connection

The method used to connect the VCI device to a vehicle's DLC depends on the
vehicle's configuration as follows:
A. 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 device,
and then tighten the captive screws.
B. Non-OBD II Vehicle Connection: For vehicles with non-OBD II diagnostic
socket, a non-16pin connector (adaptor cable) is required.
