connector: right side, under helmet
compartment, along upper frame.
Electrical characteristics:
•
STOP position: the circuit is open
•
RUN position: closed circuit (continui-
ty)
Pin-out:
1. Green/orange cable: ground connection
2. Yellow/grey cable: voltage 12V
THE CONNECTION DIAGRAMS ARE IN THE ELECTRICAL SYSTEM SECTIONS; PAY ATTENTION
TO THESE DIAGRAMS AS THEY SHOW THE CONNECTOR/COMPONENT AS VIEWED FROM
THE CABLE HARNESS SIDE, THAT IS LOOKING AT THE CABLES WHEN GOING OUT OF THE
"MAIN" CABLE HARNESS AND INTO THE CONNECTOR/COMPONENT.

Troubleshooting
•
Indication on Axone always STOP: disconnect the connector and, with the switch set to
RUN, check if there is continuity towards the switch of the two cables- yellow/grey and green/
orange: if there is not continuity, replace the sensor; if there is, check the connector. If it is
not OK, restore the cable harness; if it is OK, with key set to KEY ON, check if there is voltage
on the yellow/grey cable: if there is no voltage, restore the cable harness; if there is, check
the yellow/grey cable earth insulation: if there is continuity to ground, restore the cable har-
ness; if it is OK, take the key to KEY OFF and check the control unit connector and the
continuity of the yellow/grey cable between the connector in question and PIN 27 of the
control unit connector B "BLUE": if not OK, restore the cable harness; if OK, replace the
Marelli control unit.
•
Indication on Axone 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, it means that, with key set to KEY ON, the green/orange
cable is shorted to positive: restore the cable harness.
