4.1.1 No Communication Message
A. If the MaxiSys Display Tablet is not connected to the VCI device, an
“Error” message displays. An “Error” message indicates the display

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.
 Check the cable connection between the display tablet and the VCI
device.
 In case of wireless connection, check that the network is configured
correctly.
B. If the VCI device is unable to establish a communication link, a prompt
message displays with check instructions. The following conditions are
the possible causes for this massage to display:
 The VCI device is unable to establish a communication link with the
vehicle.
 You’ve selected a system for testing that the vehicle is not equipped
with.
 There is a loose connection.
 There is a blown vehicle fuse.
 There is a wiring fault on the vehicle, or the data cable or adapter.
 There is a circuit fault in the data cable or adapter.
