4.3.3 Vehicle connection (For Commercial Vehicle/Gasoline & Diesel
Vehicle Configuration)
The method used to connect the VCI module 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 module,
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.
*Notes:
a). For commercial vehicles, refer to the above connection method to proceed.
b). For passenger vehicles, replace the “Non-16pin connector” with “OBD I adaptor” +
“non-16pin connector (for passenger vehicles)”. Other connections shall also apply.
