The Immobilizer System - Ducati Diavel Carbon Owner's Manual

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.
The grip of each ignition key contains an electronic
device that modulates the output signal from a
special antenna located under the seat when the
ignition is switched On.
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.
