Operation
When the ignition key is turned to OFF, the immobilizer
inhibits engine operation.
When the ignition key is turned back to ON to start the
engine (Key-ON), the following happens:
1) if the CPU recognised the code, the IMMO light on the
instrument panel will flash briefly. This means that the
immobilizer system has recognised the key code and
enabled engine ignition. When you press the
button, the engine will start up.
2) If the IMMO light stays on, it means that the code has
not been recognised. When this is the case, turn the
ignition key back to OFF and then to ON again. If the
engine still does not start, try with another black key.
If the other key does not work out either, contact the
DUCATI Service network.
3) Should the IMMO pilot light still be flashing, it means
that an immobilizer system fault was reset (e.g. with the
overriding procedure through throttle grip).
Important
Use only one key during the procedure. Failure to
do so might prevent the system from recognizing the
code of the key in use.
