Safety Information
For your own safety and the safety of others, and to prevent damage to the device and
vehicles upon which it is used, it is important that the safety instructions presented throughout
this manual be read and understood by all persons operating or coming into contact with the
device.
There are various procedures, techniques, tools, and parts for servicing vehicles, as well
as in the skill of the person doing the work. Because of the vast number of test applications
and variations in the products that can be tested with this equipment, we cannot possibly
anticipate or provide advice or safety messages to cover every circumstance. It is the
automotive technician’s responsibility to be knowledgeable of the system being tested. It is
crucial to use proper service methods and test procedures. It is essential to perform tests in an
appropriate and acceptable manner that does not endanger your safety, the safety of others in
the work area, the device being used, or the vehicle being tested.
Before using the device, always refer to and follow the safety messages and applicable
test procedures provided by the manufacturer of the vehicle or equipment being tested. Use
the device only as described in this manual. Read, understand, and follow all safety messages
and instructions in this manual.
Safety Messages
Safety messages are provided to help prevent personal injury and equipment damage. All

II
safety messages are introduced by a signal word indicating the hazard level.
DANGER
Indicates an imminently hazardous situation which, if not avoided, will result in death or
serious injury to the operator or to bystanders.
WARNING
Indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury to the operator or to bystanders.
Safety Instructions
The safety messages herein cover situations iCarsoft is aware of. iCarsoft cannot know,
evaluate or advise you as to all of the possible hazards. You must becertain that any condition
or service procedure encountered does not jeopardize your personal safety.
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 carbon
monoxide, an odorless, poisonous gas that causes slower reaction time and can lead to
serious personal injury or loss of life.
SAFETY WARNINGS
Always perform automotive testing in a safe environment.
Wear safety eye protection that meets ANSI standards.
Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot engine
parts.
Operate the vehicle in a well ventilated work area, for exhaust gases are poisonous.
Put the transmission in PARK (for automatic transmission) or NEUTRAL (for manual
transmission) and make sure the parking brake is engaged.
Put blocks in front of the drive wheels and never leave the vehicle unattended while testing.
Be extra cautious when working around the ignition coil, distributor cap, ignition wires and
spark plugs. These components create hazardous voltages when the engine is running.
Keep a fire extinguisher suitable for gasoline, chemical, and electrical fires nearby.
Do not connect or disconnect any test equipment while the ignition is on or the engine is
running.
Keep the test equipment dry, clean, free from oil, water or grease. Use a mild detergent on a
clean cloth to clean the outside of the equipment as necessary.
Do not drive the vehicle and operate the test equipment at the same time. Any distraction
may cause an accident.
Refer to the service manual for the vehicle being serviced and adhere to all diagnostic
procedures and precautions. Failure to do so may result in personal injury or damage to the
test equipment.
To avoid damaging the test equipment or generating false data, make sure the vehicle
battery is fully charged and the connection to the vehicle DLC is clean and secure.
Do not place the test equipment on the distributor of the vehicle. Strong electro-magnetic
interference can damage the equipment.
Please ensure that the distance between the device and the human body is at least 20cm,
otherwise personal injury may be caused.

For the first binding, you can do as follows:
1. Enter the setting interface and tap the VCI binding option to jump to the binding
page.
Figure 2-5 VCI Device binding screen 1
2. In the interface after the jump, tap the Search VCI device button.At this time, if the
Bluetooth of the tablet device is not turned on, it will prompt to turn on the Bluetooth
first, or you can connect to the VCI through the equipped USB cable for binding.

7
Figure 2-6 VCI Device binding screen 2
3. After Bluetooth is connected, wait for the device to be searched, and tap the tablet
with the same serial number as the VCI device to bind.
Figure 2-7 VCI Device binding screen 3
4. After the binding is successful, the page will display a successful signal and display
the serial number of the VCI device.

8
Figure 2-8 VCI Device binding screen 4
5. If you need to unbind, tap the unbind button in the lower right corner, and the device
will be unbound, and you can re-bind with other VCI devices.
6. If the binding is successful, the VCI binding option on the setting page will display
the serial number of the bound VCI device.
7. In any other interface, if you need to communicate with the vehicle without VCI
binding, the tablet will give a message indicating that you need to bind the VCI, and
it will automatically jump to the binding interface after confirmation. Then follow the
instructions on the screen.
2.2.5VCI Device connection
The tablet computer can communicate with VCI via Bluetooth or USB cable. Generally,
the USB cable is faster. When the VCI is successfully bound with the tablet, it can
automatically transfer vehicle data to your tablet when it enters the vehicle diagnostic system.
At this time, the indicator light on the right side of the VCI device flashes blue and green
alternately.
The working range of Bluetooth communication is about 32.8 feet (about 10 meters); once
the device enters the transmission range of the VCI connector, the signal lost due to the out of
range will be automatically restored.
2.3Accessory Kit
2.3.1 VCI Adapter
When connected to a vehicle that complies with OBDII/EOBD, the VCI device can be
directly connected to the data link connector (DLC) of the vehicle, or the VCI device can be
