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 for issues or concerns about the product. We maintain an active database of the feedback we receive, and your comments can help us continuously improve the product.


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.

Autel Bluetooth

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.


Functional Description

The Bluetooth Diagnostic Interface device package, which includes the unit, user manual, and a CD with driver program and update agent, comes along with the MaxiSysTM/MaxiSys MiniTM tool kit. Please refer to the MaxiSys User Manual for additional information.

Technical Specifications


When used in conjunction with the display table or the OEM softwares from the PC, the Bluetooth Diagnostic Interface device is able to perform the following functions:  Auto diagnostics to read and clear the error memory, to display system parameters and the status of the ECU;  Activation, adjustments and configurations that are essential for ensuring a complete repair;  Resetting the service lights or the airbag systems;  Configuration of the ECUs, keys and remote controls, etc


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”.

8 Select “Install the software automatically (Recommended)”, and click on “Next”. After the progress bar finishes, click on “Finish”. Users have finished installing at this point and can run the software working with the interface device.
