Technical Parameter

Power Supply

Plug the device into the diagnostic interface of the vehicle, and the device will automatically start up. If it doesn’t start up, it may be that there is no power supply for the vehicle diagnostic seat, and the device can be powered by the cigarette lighter or battery clamp.
Note: the voltage of the power supply should be within the scope of application of the product equipment. If it is beyond the scope, the product may be damaged.

Vehicle Diagnostic Preparation

The diagnostic App establishes data connection with a vehicle through the VCI, which can read the vehicle diagnostic information, view the data flow, and perform action test and other functions. To establish good communication between the diagnostic program and the vehicle, the following .

operations need to be performed:

1. Turn off the ignition;
2. Find the diagnostic interface of the vehicle: it is usually located on the driver side; If the diagnostic interface is not found, please refer to the vehicle maintenance manual.
3. Insert the VCI to the vehicle’s diagnostic interface.

Note: Before the VCI is connected to the vehicle, it is necessary to judge whether the diagnostic seat of the vehicle is a OBD-II interface. The product is provided with a Diesel OBD interface cable and a CAT-9 interface cable, which are used to connect a vehicle with a corresponding interface.
The following is the operation description of two connection modes

1. OBD-II interface
   

2. Diesel OBD interface
   
   Note: at this time, the device is powered by the vehicle diagnosis seat, and the device starts automatically. If not, it may be that the vehicle diagnosis seat has no power supply, and the equipment can be powered by the cigarette lighter or battery clip.
