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.
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 Autel is aware of. Autel cannot know, evaluate
or advise you in regards of all possible hazards. You must be certain that any condition or
service procedure encountered does not jeopardize your personal safety.

iii
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.
It is not advised to use headphones at a high volume
Listening at high volumes for long periods of time may result in loss of hearing.
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, and free from oil, water, and 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 mayresult 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.

IMPORTANT
Do not disconnect the programming device while the vehicle LED status light is on. If the
flash programming procedure is interrupted while the vehicle's ECU is blank or only partially
programmed, the module may be unrecoverable.
Programming Capability
The MaxiFlash VCI device is a D-PDU, SAE J2534 & RP1210 compliant PassThru
programming interface device. Using the updated OEMsoftware, it is capable of replacing
the existing software/firmware in the Electronic Control Units (ECU), programming new
ECUs, and fixing software-controlled drivability issues and emission issues.
Communication Capability
The MaxiFlash VCI device supports Bluetooth, Wi-Fi, and USB communications. It can
transmit vehicle data to the tablet with or without a cable connection. In open areas, the
working range of the transmitter through Bluetooth communication is up to328 feet (about
100 m). The working range of 5G Wi-Fi is up to 164 feet (50 m). If the signal is lost due to
being taken out of range, communication will be restored once the tablet is within range.
2.2.2 Power Sources
The VCI device can receive power from the following sources:
Vehicle Power
AC/DC Power Supply
Vehicle Power
The VCI device operates on 12/24 Volt vehicle power, which receives power via the
vehicle data connection port. The device powers on whenever it is connected to an
OBDII/EOBD compliant data link connector (DLC). For non OBDII/EOBD compliant
vehicles, the device can be powered from an auxiliary power outlet adapter or other
suitable power port on the test vehicle using the auxiliary power cable.

2.4 Accessories Kit
2.4.1 Main Cable
The VCI device can be powered through the Autel Main Cable V2.0 (the V2.0 icon can be
seen on the cable) when connected to an OBDII/EOBD compliant vehicle. The Main Cable
connects the VCI device to the vehicle's data link connector (DLC), through which the VCI
device can transmit vehicle data to the tablet.
Figure 2-6 Main Cable –1.5m in Length
NOTE
MaxiFlash VCMI and MaxiFlash VCI can beconnected by theAutel Main Cable V2.0 only.
DO NOT use other Autel maincables to connect the MaxiFlash VCMI and MaxiFlash VCI.
2.4.2 Non-OBDII Adapters
The adapter used depends on the type of vehicle being tested. The most common
adapters are shown below.
