The Immobilizer system
For improved antitheft protection, the motorcycle is
equipped with a 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. 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 acts as a password (which is
different at each start-up) and tells the ECU that an
"authorised" ignition key is being used to start up the
engine. When the ECU recognises the signal, it
enables engine start-up.
