USB Cable Connection
The USB cable connection is a simple and quick way to establish
communication between the MaxiCOM display 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 tick icon in a
few seconds, and the USB LED on the VCI device illuminates solid green light,
indicating the connection between the devices is successful.
The MaxiCOM diagnostic platform is now ready to perform vehicle diagnosis.
NOTE: Since the USB connection provides the most stable and fastest
communication, it is highly recommended to apply this communication method
when operating ECU programming or coding. When all the two communication
methods are applied at the same time, the MaxiCOM system will use the USB
communication as the default priority.
4.1.3 No Communication Message
A. If the MaxiCOM Display Tablet is not connected to the VCI device, an
“Error” message displays. An “Error” message indicates the display 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, the communication is suddenly
interrupted due to the loss of signal, check if there is any object 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 display tablet and the VCI device.
⚫ Check if the green LED on the VCI device is illuminated for BT or
USB.
