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 safety messages are introduced by a signal word
indicating the hazard level.
Indicates an imminently hazardous situation which, if not avoided, will
result in death or serious injury to the operator or to bystanders.
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 Autel is aware of. Autel
cannot know, evaluate or advise you as to all of the possible hazards.
You must be certain that any condition or service procedure encountered
does not jeopardize your personal safety.
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
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
Put the transmission in PARK (for automatic transmission) or NEUTRAL
(for manual transmission) and make sure the parking brake is
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
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
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.

electronic control unit (ECU) for various vehicle control systems, including
engine, transmission, antilock brake system (ABS), airbag system (SRS).
Establishing Vehicle Communication
The Diagnostics operations require connecting the MK808BT Diagnostic
Platform to the test vehicle through the MaxiVCI Mini. To establish proper
vehicle communication to the tablet, please perform the following steps:
1. Connect the MaxiVCI Mini to the vehicle’s DLC for both
communication and power supply.
2. Connect the MaxiVCI Mini to the tablet via BT pairing.
3. A green check will display atop the VCI navigation button at the
bottom bar on the screen. If communication has been established,
the MK808BT is ready to start vehicle diagnosis.
Vehicle Connection
The tablet communicates with the vehicle via the BT connection provided
by the MaxiVCI Mini.
To connect the MaxiVCI Mini to the test vehicle, simply insert the Vehicle
Data Connector on the MaxiVCI Mini into the vehicle’s DLC which is
generally located under the vehicle dash and the MaxiVCI Mini will be
automatically powered on.
The vehicle’s DLC is not always located under the dash; refer to the
vehicle’s user manual for DLC location.
VCI Connection
The MaxiVCI Mini Power LED will light solid green when properly
connected to the vehicle and ready to establish communication with the
tablet.
The wireless diagnostic interface MaxiVCI Mini supports 2 communication
methods with the tablet, wireless BT and USB.
BT Connection
BT pairing is recommended as the first choice for the communication
between the tablet and the MaxiVCI Mini. The working range for BT
communication is about 33 feet (about 10 m), enabling remote vehicle
diagnostics.
More than one MaxiVCI Mini to connect to the test vehicles, you can
perform vehicle diagnosis on various vehicles conveniently by pairing the
tablet separately to each of the MaxiVCI Mini devices connected to the
different test vehicles via wireless BT. Without the need to repeat the
plugging and unplugging procedure which is unavoidable through
traditional wired connection, BT connection saves you more time and
provides higher efficiency.
Refer to BT Pairing on page 91 for details.
USB Cable Connection
Use the provided USB cable to connect the tablet to the MaxiVCI Mini. A
green check will display atop the VCI navigation button at the bottom bar
of the screen and the MaxiVCI Mini Connection LED will light solid green
when connection between the devices is successful.
The USB communication method will take priority over BT communication
No Communication Message
A. If the tablet is not connected to the MaxiVCI Mini correctly, an “Error”
message may display. This indicates that the tablet cannot access
the vehicle control module. In this case, please do the following
Check if the MaxiVCI Mini is powered up.
Check if the MaxiVCI Mini is properly positioned.
Check if the Connection LED on the MaxiVCI Mini is illuminated for
In case of BT connection, check if the network is configured
correctly, or if the right MaxiVCI Mini has been paired up with the
If during the diagnosis process, the communication is
suddenly interrupted due to the loss of signal, check if there
is any object that causes signal interruption.
Try standing closer to the MaxiVCI Mini to obtain more stable
signals and faster communication speed.
In case of USB connection, check the cable connection between
the tablet and the MaxiVCI Mini.
Check if the Power LED on the MaxiVCI Mini is flashing red and if
so, it indicates there is a hardware problem with the MaxiVCI
Mini, in this case, contact technical support for help.
B. If the MaxiVCI Mini is unable to establish a communication link, a
prompt message displays with check instructions. The following
conditions are the possible causes:
The MaxiVCI Mini is unable to establish a communication link with
The system selected for testing is not equipped on the vehicle.
There is a loose connection.
There is a blown vehicle fuse.
There is a wiring fault of the vehicle or the adapter.
There is a circuit fault in the adapter.
Incorrect vehicle identification was entered.
Getting Started
Ensure a communication link is established between the test vehicle and
the tablet via the MaxiVCI Mini.
