NOTE
The USB connection provides the most stable communication and is therefore the
recommended communication mode between the tablet and VCMI when operating ECU
programming or coding. The USB communication method will take priority over other
connected communication modes.
4.1.1.3 No Communication Message
A. If the tablet is unable to connect to the VCMI, an “Error” message displays. An “Error”
message indicates the tablet is not communicating with the VCMI device,
Troubleshoot the error by performing the following steps:
 Ensure the VCMI device is powered on.
 When using the wireless connection, ensure the network is configured correctly
and the proper device has been connected.
 If the tablet loses communication abruptly during diagnostics, ensure no objects
are causing signal interruption.
 Ensure the VCMI device is properly positioned with the VCMI front side up.
 Move the tablet closer to the VCMI device. If using the wired connection, ensure
the cable is securely attached to the VCMI.
 Ensure the VCMI communication mode is lit for the selected communication
type, BT, Wi-Fi or USB.
B. If the VCMI device is unable to establish a communication link, a message will
display troubleshooting instructions. Possible causes for the communication error
include:
 The VCMI device is unable to establish a communication link with the vehicle.
 A vehicle system has been selected for diagnoses that is not supported by the
vehicle.
 There is a loose connection.
 There is a blown vehicle fuse.
 The vehicle or the data case has a wiring fault.
 There is a circuit fault in the data cable or adapter.
 The vehicle identification is incorrectly entered.
