The Immobilizer System - Ducati Monster 1200 Owner's Manual

Once the "Hazard" function is activated, if vehicle is
turned off (i.e. key turned to "OFF"), the function stays
active until manually turned off by the user or as long
as the battery voltage is 12.2 V. If voltage is < 12.2
V the turn indicators will turn off automatically in order
to save battery charge.
Note
If user performs a Key-ON while the "Hazard"
function is still active, the function will remain ON
(temporary turn indicator control interruption is
allowed during the instrument panel initial check
routine).
Note
If there is a sudden interruption in the battery
while the function is active, the instrument panel will
disable the function when the voltage is restored.
Note
The "Hazard" function has higher priority
compared to normal operation of the single turn
indicators, this means that, as long as it is active, it
will not be possible to activate the single right or left
turn indicators.

The Immobilizer system

For improved anti-theft protection, the motorcycle is
equipped with an IMMOBILIZER, an electronic
system that inhibits engine operation whenever the
ignition switch is turned off.
Housed in the handgrip of each ignition key is an
electronic device that modulates an output signal.
When the ignition is turned on this signal is generated
by a special antenna incorporated in the switch and
changes every time.
The modulated signal represents the "password"
(which is changed at each start-up) by which the ECU
recognizes the ignition key. The ECU will only allow
the engine to start if it recognizes this password.
