Ducati XDIAVEL Owner's Manual page 251

When you press function button (8) of the left-hand
switch to confirm the fourth and last digit:
- if the PIN code is not correct, the instrument
panel displays PIN CODE WRONG for three
seconds and then highlights the string of four
zeros ("0") to allow you to try again. The number
of possible attempts is determined by a preset
time-out of two minutes.
- if the PIN CODE is correct, the instrument panel
shows PIN CODE CORRECT for three seconds,
and then displays the "standard screen".
Important
If this procedure is necessary in order to start
the motorcycle, contact an Authorised Ducati Service
Centre as soon as possible to fix the problem.
