AXONE: STATUSES
Run / stop switch
Example value:Run/Stop
Indication on Axone always STOP: disconnect the connector and, with the switch set to RUN, check if
there is continuity toward the switch of the two yellow/grey and red/black cables: if there is no continuity,
replace the sensor; if there is, check the connector. If not OK, restore the cable harness; if it is OK, with
key set to ON, check if there is voltage to the red/black 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 harness; if it is correct, take the key to OFF and check the VEHICLE connector is in good
conditions and the continuity of the grey/yellow cable between the sensor in question and the VEHICLE
connector PIN 26: 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 ON, the yellow/grey cable is short circuit to positive: restore the
cable harness.
