USB Cable Connection
The USB cable connection is a simple and quick way to establish communication
between the tablet and the VCI device. After properly connecting the USB cable from
the tablet to the VCI device, the VCI navigation button at the bottom bar of the screen
shows a green check in a few seconds, and the USB LED on the VCI device illuminates
solid green, indicating the connection between the devices is successful.
The MaxiSys diagnostic platform is now ready to perform vehicle diagnosis.
No Communication Message
A. If the tablet is not connected to the VCI device, an “Error” message displays. An
“Error” message indicates the tablet is not communicating with the VCI device, and
so cannot gain access to the vehicle control module. In this case, you need to do
the following check-ups:
⚫ Check if the VCI device is powered on.
⚫ In case of wireless connection, check if the network is configured correctly, or
if the right device has been paired.
⚫ If during the diagnosis process, communication is suddenly interrupted due to
the loss of signal, check if there are any objects that causes signal
interruption.
⚫ Check if the VCI device is properly positioned. It is recommended to put the
VCI device with the front side up.
⚫ Try standing closer to the VCI device to obtain more stable signals, and faster
communication speed. In case of wired connection, check the cable
connection between the tablet and the VCI device.
⚫ Check if the green LED on the VCI device is illuminated for BT or USB.
⚫ Check if the Error LED on the VCI device is on, this may indicate there is a
communication error between the devices, in this case try re-establishing the
connection again; if this does not work, there may be a hardware problem with
the device, in this case contact Autel or local distributor for technical support.
