Code card
The keys come with a CODE CARD (fig. 15) that reports:
A) (fig. 16) the electronic code to be used in case of
engine block, i.e. bike did not start after key-ON.
Warning
Keep the CODE CARD in a safe place. However, it
is advisable to keep the electronic code printed on the
CODE CARD handy when you ride your motorcycle, in
case it is necessary to override engine block through the
procedure that uses the throttle twistgrip.
In case of faulty immobilizer system, the following
procedure gives the chance to disable "engine block"
function -signalled by the orange EOBD warning light that
comes on (8, fig. 4).
But this operation can be carried out only if the electronic
code indicated on the code card is known.
