Indication on Navigator always STOP: disconnect the connector and, with the switch set to
RUN, check if there is continuity towards the two cables switch - Blue/Green and Yellow/
Red: If there is not continuity, replace the sensor; if there is continuity, check the connector:
if not OK, restore the cable harness; if OK, check, with key set to ON, if there is voltage on
Yellow/Red cable: if there is no voltage, restore the cable harness; if there is, check the
Yellow/Red cable ground insulation: If there is continuity with ground connection, restore
the cable harness; if OK, set the key to OFF and check the VEHICLE connector and the
engine-vehicle cable harness connector: if not OK, restore; if OK, check continuity of the
Pink cable between switch connector and PIN C7 of the engine-vehicle cable harness con-
nector and between the PIN C7 and the VEHICLE connector PIN 78: if not OK, restore the
cable harness; if OK, replace the Marelli control unit.
•
Indication on Navigator always RUN: disconnect the connector and, with the switch set to
STOP, check if there is continuity between the two cables of the switch: if there is continuity,
replace the switch; if there is not continuity, it means that, with key set to ON, the Pink cable
(between switch and the PIN C7 of the engine-vehicle cable harness connector or from the
latter to the PIN 78 of the control unit connector) is shorted to positive: restore the cable
harness.
Butterfly valve in exhaust
Function
It is used to reduce exhaust noise. The exhaust
butterfly valve is managed as follows:
•
With engine off: open by 75%
•
With engine running: regardless of the
gear engaged, below 5,500 rpm and
below 14° of throttle opening it is fully
closed; over 6,500 rpm or 16° of throttle
opening it is fully open; under any other
condition it is in an intermediate posi-
tion. With bike stopped and in neutral
the valve stays closed, regardless of
rpm.
