Important Safety Precautions
To avoid personal injury, property damage, or accidental damage to the product,
read all of the information in this section before using the tool.
DANGER
• When an engine is operating, keep the service area well-ventilated or attach
a building exhaust removal system to the engine exhaust system. Engines
produce various poisonous compounds (hydrocarbon, carbon monoxide,
nitrogen oxides, etc.) that cause slower reaction time and result in death or
serious personal injury.
• Please use the included battery and power adaptor. Risk of explosion if the
battery is replaced with an incorrect type.
• DO NOT attempt to operate the tool while driving the vehicle. Have second
personal operate the tool. Any distraction may cause an accident.
WARNING
Always perform automotive testing in a safe environment.
Do not connect or disconnect any test equipment while the ignition is on or
the engine is running.
Before starting the engine, put the gear lever in the Neutral position (for
manual transmission) or in the Park (for automatic transmission) position to
avoid injury.
NEVER smoke or allow a spark or flame in vicinity of battery or engine. Do
not operate the tool in explosive atmospheres, such as in the presence of
flammable liquids, gases, or heavy dust.
Keep a fire extinguisher suitable for gasoline/chemical/electrical fires nearby.
Wear an ANSI-approved eye shield when testing or repairing vehicles.
Put blocks in front of the drive wheels and never leave the vehicle unattended
while testing.
Use extreme caution when working around the ignition coil, distributor cap,
ignition wires and spark plugs. These components create hazardous voltage
when the engine is running.
To avoid damaging the tool or generating false data, please make sure the
vehicle battery is fully charged and the connection to the vehicle DLC (Data
Link Connector) is clear and secure.

Automotive batteries contain sulfuric acid that is harmful to skin. In operation,
direct contact with the automotive batteries should be avoided. Keep the
ignition sources away from the battery at all times.
Keep the tool dry, clean, free from oil, water or grease. Use a mild detergent
on a clean cloth to clear the outside of the equipment when necessary.
Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or
hot engine parts.
Store the tool and accessories in a locked area out of the reach of children.
Do not use the tool while standing in water.
Do not expose the tool or power adapter to rain or wet conditions. Water
entering the tool or power adaptor increases the risk of electric shock.
This tool is a sealed unit. There are no end-user serviceable parts inside. All
internal repairs must be done by an authorized repair facility or qualified
technician. If there is any inquiry, please contact the dealer.
Keep the tool far away from magnetic devices because its radiations can
damage the screen and erase the data stored on the tool.
Do not attempt to replace the internal rechargeable lithium battery. Contact
the dealer for factory replacement.
Do not disconnect battery or any wiring cables in the vehicle when the ignition
switch is on, as this could avoid damage to the sensors or the ECU.
Do not place any magnetic objects near the ECU. Disconnect the power
supply to the ECU before performing any welding operations on the vehicle.
Use extreme caution when performing any operations near the ECU or
sensors. Ground yourself when you disassemble PROM, otherwise ECU and
sensors can be damaged by static electricity.
When reconnecting the ECU harness connector, be sure it is attached firmly,
otherwise electronic elements, such as ICs inside the ECU, can be damaged.

4.1 Preparation
The vehicle ignition is turned on.
The vehicle battery voltage range is 11-14 volts.
The throttle is in the closed position.
Find DLC location.
The DLC(Data Link Connector) is usually located 12 inches from the center of the
instrument panel, under or around the driver’s side for most vehicles. For some
vehicles with special designs, the DLC location may vary. Refer to the following
figure for location.
A. Opel, Volkswagen, Audi
B. Honda
C. Volkswagen
D. Opel, Volkswagen, Citroen
E. Changan
F. Hyundai, Daewoo, Kia, Honda, Toyota, Nissan, Mitsubishi, Renault, Opel, BMW,
Mercedes-Benz, Mazda, Volkswagen, Audi, GM, Chrysler, Peugeot, Regal, Beijing
Jeep, Citroen and other most popular models
If the DLC cannot be found, refer to the vehicle’s service manual for the location.
4.2 Vehicle connection
The method used to connect the VCI connector to a vehicle’s DLC depends on
the vehicle’s configuration as follows:
A vehicle equipped with an OBD II management system supplies both

communication and 12V power through a standardized DLC.
A vehicle not equipped with an OBD II management system supplies
communication through a DLC connection, and in some cases supplies 12V
power through the cigarette lighter receptacle or a connection to the vehicle
battery.
Follow the steps mentioned below to connect OBD II vehicle:
Use the included OBD II extension cable to connect the VCI connector to the
vehicle’s DLC port (recommended) / Plug the VCI connector into the vehicle’s
DLC port directly.
For non-OBDII vehicle, proceed as follows:
1. Locate vehicle’s DLC socket.
2. Select the corresponding non-16pin connector.
3. Plug the non-16pin end of the connector into the DLC socket, then connect
the other end to the OBD I adaptor, and then tighten the captive screws.
4. Connect the other end of the adaptor to the VCI connector.
Note: If the pin of the DLC is damaged or the DLC has insufficient power, you can
get power via either of the following methods:

5 Diagnosis
5.1 Intelligent Diagnosis
Through simple Bluetooth communication between the display tablet and VCI,
you can easily get the VIN (Vehicle Identification Number) information of the
currently identified vehicle. Once the VIN is successfully identified, the system
will retrieve it from the remote server and then guide you to vehicle information
page without the necessity of step-by-step manual menu selection.
The vehicle information page lists all historical diagnostic records of the vehicle,
which lets the technician have a total command of the vehicle faults. In addition,
a quick dial to local diagnosis and diagnostic function are also available on this
page for reducing the roundabout time and increasing productivity.
Notes:
• Before using this function, please make sure the VCI is properly connected to the
vehicle’s DLC. For detailed connection, see Chapter 4.2.
• A stable network connection is required for this function.
Follow the steps below to proceed.
1. Tap Intelligent Diagnose on the Job menu to start pairing with the VCI.
2. After pairing is complete, the tablet starts reading the vehicle VIN.
A. If the VIN can be found from the remote server database, the following
