14 DIAGNOSIS
The protocols supported by the VCI allow it to perform various types of diagnoses.
The type of diagnosis that can be carried out depends on the vehicle being tested and its
compliance with specific protocols for communication with the control units.
The type of diagnosis also determines the communication mode between the VCI and the
display unit.

Where possible, the selection of the type of diagnosis is carried out through specific functions
in the diagnostic software.
Carrying out diagnostic tests using the functions made
available by the software requires you to read and accept
specific disclaimers.
Such disclaimers contain important safety indications that you
must have read and fully understood before carrying out the
tests.
To carry out diagnostic tests, you must have previously
configured the communication between the VCI and the
display unit.
Some types of diagnostic operations require specific
communication modes.
For further information, see the software operating manual.
The diagnostic connection is always established through a specific wiring indicated by the
diagnostic software.
The diagnostic cable must be connected to the DIAGNOSIS connector on one end, and to
the diagnostic socket in the vehicle being tested on the other end.
For further information on the positioning and correct access to the
diagnostic socket, refer to the documentation made available by the vehicle
manufacturer.
