The Immobilizer System - Ducati 749R 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.
Accommodated in the handgrip of each ignition key is an
electronic device that modulates an output signal. This
signal is generated by a special antenna incorporated in the
switch when the ignition is turned on and changes every
E
time. The modulated signal acts as a "password" and tells
the CPU that an "authorised" ignition key is being used to
start up the engine. When the CPU recognises the signal,
it enables engine start-up.
Keys (fig. 14)
The Owner receives a set of keys comprising:
- 1 RED key A
- 2 BLACK keys B
Warning
Red key A has a rubber cover for preserving it in
perfect conditions and avoiding contact with other keys.
Never remove this protection unless really needed.
The keys B are regular ignition keys and are used to:
- start up the engine
- open the lock of the fuel tank filler plug
- open the seat lock (Biposto).

The key A performs the same functions as the keys B, and
is also used to wipe off and re-program other black keys, if
needed.
Note
The three keys have a small plate (1) attached that
reports their identification number.
Warning
Keep the keys in different places. Store the plate (1)
and the key A in a safe place.
It is also recommended to use always the same black key
to use the bike.
