If the fuse in question is in good condition, proceed
with the check of the speed sensor as follows:
Keeping the sensor connected to the system and with
the key in the ON position, using a tester, check that
when the sensor is positioned in front of one of the nuts
of the brake disk, between terminal 3 and terminal 2 of
the connector, the voltage is close to zero, whilst when
it is not placed in front of one of the nuts, the voltage is
close to that of the battery.

LOW BEAM HEADLIGHT

In the event that the dipping beam does not work,
check the conditions of fuse 3 on the fuse box. If this
fuse is ok, check the conditions of the relay situated on
the left side of the motorcycle, with the label "B".
If this is also ok, check continuity of the R/W cable
which goes from relay "B" to the engine control unit at
terminal 31.
