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 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. 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. E 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). B A 1 fig. 14 19
