The Immobilizer system
For improved antitheft 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.
Keys
(fig. 128)
The owner receives 2 keys with the vehicle.
These keys contain the "immobilizer system code".
The keys (B) are regular ignition keys and are used to:
- start up the engine.
- open the fuel tank filler plug.
- open the seat lock.
Warning
It is also advisable to use only one of the keys to
start the motorcycle.
Operation
When the ignition key is turned to OFF, the
immobilizer inhibits engine operation. If the other key
does not work out either, contact the Ducati Service
network.
Warning
Any important shock might damage the
electronic components fitted into the key.
Use only one key during the procedure. Failure to do
so might prevent the system from recognizing the
code of the key in use.
