General Notice
The Bluetooth Diagnostic Interface has been carefully designed and tested to
comply with OBDII protocols. However, some vehicle models are not in full
compliance with these protocols for various reasons. In addition, the computer
control systems or sensors on any given vehicle may be malfunctioning.
While Autel’s testing and the experiences of the users have shown the unit to
be safe and reliable, there is an inherent risk in using any product that may
potentially affect the operation or drive-ability of your vehicle.
If you are concerned about the operation of your vehicle at any time while
using the Bluetooth Diagnostic Interface:
Pull off the roadway immediately or as soon as it is safe to do so.
Disconnect the device from the OBDII port.
Consult a licensed mechanic or automobile service center.
Contact your local distributor, or visit www.auteltech.com for issues or
concerns about the product. We maintain an active database of the feedback

Introduction
The Bluetooth Diagnostic Interface is a multi-brand device which comes with
the MaxiSys tool kit. It is designed to connect wirelessly with the MaxiSys
Display Tablet, as well as standalone PCs, as a vehicle communication
interface (VCI) for vehicle data transmission. Thanks to the wireless Bluetooth
technology, with which you are allowed to work freely around the vehicle.
This interface device can communicate with vehicles’ electronic control units
(ECUs), guaranteeing performance and speed that redefine multi-brand
diagnostics. The development of this interface has been focused on reducing
the communication time, and ensuring the tool is practical to use.
The MaxiSys diagnostic platform combines the VCI device and the display
tablet with technical information into a single program, ensuring quick and
simple access to the vehicle to perform comprehensive diagnostics
applications.

Wireless Communication
The Bluetooth Diagnostic Interface supports Bluetooth communication. It can
transmit vehicle data to the MaxiSys Display Tablet without a physical
connection. The working range of the transmitter through Bluetooth
communication is about 755 feet (about 230 m). A signal lost due to moving
out of range automatically restores itself when the display unit is brought
closer to the VCI unit.
For detailed information about VCI connection with the MaxiSys display tablet,
please refer to the MaxiSys User Manual.
USB Connectivity
The VCI device also provides a direct connection to the MaxiSys display tablet
or a PC via a USB 2.0 full-speed connection. All of the electronics are
contained in the device shell, making it a compact and rugged vehicle
communication tool.
Power Source
The Bluetooth Diagnostic Interface operates on 12-volt vehicle power, which it
receives through the vehicle data connection port. The unit powers on
whenever it is connected to an OBD II/EOBD compliant data link connector
(DLC).
It can also be powered through connection with a PC via the USB cable, so
there’s no need to connect the device to the vehicle when performing firmware
update through the PC.

Product Troubleshooting
This part describes problems that you may encounter while using the VCI
device.
Vehicle Linking Error
A communication error occurs if the interface device fails to communicate with
the vehicle’s control module when performing diagnostic procedures. You
need to do the following check-ups:
Verify that the ignition is ON.
Check if the interface device’s OBD II connector is securely connected to
the vehicle’s DLC.
Turn the ignition off and wait for about 10 seconds. Turn the ignition back
to on and continue the operation.
Verify the control module is not defective.
PC Communication Error
Verify the interface device is powered, and the green power LED is
illuminated.
Check if there is any firewall software interfering with the connection
port.
Check if the green status light is illuminated for USB communication.
If these issues have been addressed, verified, and you are still having trouble,
please contact technical supports for assistance. Refer to the MaxiSys User
Manual for additional information.

Driver Setup
In order for the Bluetooth Diagnostic Interface device to operate correctly with
the diagnostic applications on the PC, you will need to first install the device’s
driver onto the PC that controls the device.
The program package requires Windows XP, Windows Vista (32 or 64 bit), or
Windows 7 (32 or 64 bit).
IMPORTANT: Do not plug the interface device onto the PC until you have
installed the driver program.
The following steps may vary depending on the operating system or
components that are installed on your computer, but in general this is the
standard installation process.
1 Insert the CD that came with the MaxiSys tool kit into the CD/DVD slot of
the PC. The driver installation wizard will load momentarily. Follow the
Setup Wizard instructions to complete the whole installation process.

2 Click on “Next”on the welcome page.
3 Select “Next”on the installation location and installation name. It is
recommended not to change the default settings; otherwise the
computer may have a hard time recognizing the driver.
4 Click on “Install”and the driver program will be installed onto your PC.
NOTE: During this part of the process a MS-DOS style window will pop
up and may remain on your screen for a short while, which is perfectly
normal. Do not attempt to close the MS-DOS style window manually as
this will prevent the device driver being installed successfully. It will close
automatically when the device driver installation is complete.
5 When the driver is successfully installed, a confirm window will appear.
6 Click on “Finish”, and connect the interface device to the PC’s USB port.
7 A “Found New Hardware Wizard”window will pop up. Make sure “No,
not this time”is selected and click on “Next”.
