The Immobilizer System; Keys - Ducati MULTISTRADA 1100 S Use And Maintenance 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.
In the handgrip of each ignition key is an electronic device
that modulates the signal sent by a special antenna in the
switch during start-up. The modulated signal represents
E
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

(fig. 13)
The owner receives a set of keys, comprising:
- 1 red key (A)
The red key is a service tool and is part of the
motorcycle's immobilizer system. It contains the code
of the immobilizer system and should not be used for
normal everyday use of your motorcycle. Your dealer
may ask you to produce the red key in order to carry
out certain service operations.
For security reasons, the red key cannot be replaced.
In cases where the red key is required for servicing
purposes and the owner is unable to produce it, it will
be necessary to renew the motorcycle's electronic
control unit, instrument panel and ignition switch
assembly, and the cost of these operations will be
met by the owner. It is therefore important to keep
the red key in a safe place.
- 2 black keys (B)

Warning
The red key (A) has a rubber sleeve to keep it in perfect
condition, and prevent contact with other keys. Never
remove this protection unless absolutely necessary.
The B keys are the keys for normal use, and are used to:
- start the engine;
- open the fuel tank filler plug;
- open the document compartment cover;
- open the passenger seat lock.
The A key performs all the same functions as the B keys and
it can also be used to reset and re-program other black keys
if necessary.
