3 HOW TO DIAGNOSE
3.1 CONNECT VCI CONNECTOR
Procedure to connect VCI connector:
1. Locate vehicle’s DLC socket. The DLC (Data Link Connector or Diagnostic Link Connector) is the
standardized 16‐cavity connector where diagnostic code readers interface with the vehicle's
on‐board computer. The DLC is usually located 12 inches from the center of the instrument panel
(dash), under or around the driver’s side for most vehicles. If Data Link Connector is not located
under dashboard, a label should be there telling location. For some Asian and European vehicles,
the DLC is located behind the ashtray and the ashtray must be removed to access the connector.
If the DLC cannot be found, refer to the vehicle’s service manual for the location.

2. Plug the VCI diagnostic connector into the vehicle’s DLC socket (It is suggested to use the OBD
2 extension cable to connect VCI connector and DLC socket.). For non‐16PIN DLC socket, please
select the corresponding non‐16 pin connector adapter, then plug the non‐16pin end
of the adapter into the DLC socket, and then connect the standard 16pin end VCI connector.

3.2 BLUETOOTH SETTING
1．Enter Key Master to set System setting, and choose VCI information.
2．Operate according to following prompt:
A．“Please match: VCI_888888888888(Bluetooth name)”
b．“Connected: VCI_888888888888(Bluetooth name)”
C．“Not connected: VCI_888888888888(Bluetooth Name)” Please connect VIC connector to
vehicle, X300 DP will connect automatically.
