Procedure to disable immobilizer engine block
through throttle twistgrip
1) Turn the key to ON and fully open throttle. Keep it
open. The EOBD warning light turns off after 8 seconds.
2) Release the throttle as soon as the EOBD warning
light turns off.
3) EOBD pilot light will flash. Count a number of flashes
corresponding to the first figure of the code, open full
throttle and keep the position for 2 seconds, then
release. In this way the input of one figure is
E
acknowledged, EOBD pilot light comes on and stays on
for 4 seconds. Carry out the same procedure for the
following figures of the code. Failure to do so will cause
the EOBD pilot light to flash 20 times, then it will stay on.
This means that the procedure has been aborted. It will
be necessary to turn the key to OFF and restart from
point (1).
4) Repeat operations described in point (3) up to the last
figure of the code.
5) When you release the throttle, if the code was
inserted in the correct way, you can have two situations,
A or B:
A) the EOBD light starts flashing to indicate that engine
is enabled. The light goes off after 4 seconds, or if the
engine runs faster than 1000 rpm.
B) the CODE light flashes until engine rpm stays below
1000, or until the vehicle is restarted.
6) Should the code NOT be entered correctly both the
EOBD and CODE lights stay on and it is possible to
repeat the procedure starting again from point 2 for as
many times as necessary.

Note
Should the throttle twistgrip be released before the
set time, the warning light turns on again. It is then
necessary to bring the key to OFF and restart the
procedure from point (1).
