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
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
4) Repeat operations described in point (3) up to the last
figure of the code.
5) Release the throttle twistgrip, if the code is correct,
the EOBD warning light shall flash signalling that engine
block has been disabled. The warning light turns off after
If the code is NOT correct, the EOBD warning light stays
on and it is then possible to turn the key to OFF and
repeat the procedure, starting from point (1), as many
times as necessary (infinite).
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).
