• The engine exhaust gas contains a variety of toxic compounds, which one should avoid breathing in. During the operation, park the vehicle in a well-ventilated place.

• When the engine is running, the temperature is very high; please avoid contact with the water tank, exhaust pipe and other high temperature components.

• Before starting the engine, apply the handbrake and place the shift lever in Gear Neutral
  (Manual Transmission) or P (Automatic Transmission) to avoid sudden movements of the vehicle when starting the engine.

• Before repairing the vehicle, apply the parking brake, engage the Neutral or P range, and lower the driver seat’s glass doors.

• If the engine can be started, warm-up the vehicle to normal temperature (water temperature is about 80 °C), and turn off the auxiliary electrical appliances (such as air conditioning, lighting, sound, etc.).

Find the diagnostic socket; check and confirm the diagnostic socket cables are in good condition, connecting the main unit for diagnosis. Otherwise, do not test, to avoid damage to the main unit. If necessary, use a multimeter to measure the voltage of the diagnostic socket.

Product Overview

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 program establishes data connection with a vehicle through the VCI, which can read the vehicle diagnostic information, view the data flow, and perform action tests 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’s side; If the diagnostic interface is not found, please refer to the vehicle maintenance manual.
  3. Insert the VCI into the vehicle’s diagnostic interface.

At this time, the device is powered by the vehicle diagnosis seat and starts automatically.

Tips:
If the vehicle diagnosis seat is too small, so that you can’t insert the VCI into the diagnosis interface, you can use an extended cable, shown as the figure below.

Fcar provides the cable, you can purchase it from your product seller.
