The Immobilizer System - Ducati MONSTER 1100 S Owner's Manual

The immobilizer system

For additional anti-theft protection, the motorcycle is
equipped with an IMMOBILIZER, an electronic system
that locks the engine automatically 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 in the switch 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 recognises this password.

Keys
The owner receives a set of keys, comprising:
- 2 black keys (B).
These contain the "code" of the immobilizer system.
Notes
Your Ducati dealer may ask you to produce your Code
Card in order to carry out certain servicing operations.
The black keys (B) are the keys for normal use, and are
used to:
- start the engine;
- open the lock on the fuel tank filler cap;
- open the seat lock.
