For additional antitheft 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 located under the seat when the ignition is switched on.
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.
Abs disabling function
Keys (fig. 62)Operating principle of dtc
The bbs receives the front and rear speed information from the abs over the
can. Then, the bbs sends the vehicle speed
information to be displayed on the dashboard over the can.
If the tangential speed of the rear wheel exceeds the tangential speed of the
front wheel by a given percentage, t ...
Air temperature sensor
Introduction
The engine control system on the diavel uses a sensor that measures air
temperature. This sensor has a resistance of
ntc type (negative temperature coefficient), that reduces its own value when the
temperature increases. The air
temperature sensor allows the engine control unit t ...
Programming/reprogramming keys
The dds diagnosis instrument is required in order to programme/reprogramme
the keys. The key programming procedure
is launched from this instrument.
To start the key programming/reprogramming procedure it is necessary to have at
least one of the keys that start the
vehicle available (i.E. I ...
