With ignition key at MAR, if au-
thentication fails, system starts work-
ing as usual, but the user is asked to
enter the 4-digit “Master Code” to al-
low access to the standard functions.
Master code is unique for each sys-
tem, and is stored in its memory and
can not be reset.

tion,

similar to PIN insertion request, but
the dialog box itself is generated on a
wholly blackened screen.

PROTECTION
AGAINST THEFT
Power-on authentication
procedure
The system is protected against theft
and unauthorised installation by means
of an “authentication procedure”.
This kind of verification involves
Body Computer Node (by means of
messages exchanged on vehicle net-
work) and is performed at every pow-
er-on.
The procedure will not take place if
the system is switched on by means of
knob 16-fig. 1or button
•25-fig. 1
and ignition key at STOP. In this case,
the system is enabled to work nor-
mally, without authentication proce-
dure.After the code is entered, a second
screen notices the user that the au-
thentication procedure is in progress,
fig. 4.
In case the correct code is provided,
the system is fully enabled. On the
contrary, if a wrong code is entered,
screen is cleared and previous box is
shown again with the following string:
“Incorrect code entered. Enter Mas-
ter Code not turn off system.
There is no upper limit to the num-
ber of wrong codes that can be en-
tered.
