Electrical system
BEFORE CARRYING OUT ANY TROUBLESHOOTING, CAREFULLY READ THE GENERAL CON-
CEPTS OF ELECTRICAL TROUBLESHOOTING FOUND AT THE BEGINNING OF THE CHECKS
AND CONTROLS SECTION IN THE ELECTRICAL SYSTEM CHAPTER.
AXONE: STATUSES
Gear in neutral
Example value:yes/no
AXONE: NOTES
•
Indication on the instrument panel always gear engaged: check the correct position of the
cable terminals on the connector and the correct connection of the cables on the terminals.
If they are not correct, restore the cable harness; if correct, disconnect the connector and,
with gear in neutral, check continuity to terminal ground connection, sensor side: if there is
no continuity, replace the sensor (after checking cable continuity on the sensor side and the
correct mechanical position). If there is, check the correct position of the terminal on the
control unit connector and the correct connection of the cables on the terminals. If they are
not correct, restore the cable harness; if OK, check the cable continuity between the sensor
connector and ENGINE connector PIN 16: if there is no continuity, restore the cable harness.
If there is, replace the instrument panel if the vehicle performance is correct (the engine
starts with gear in neutral but the neutral warning light is off) or replace the control unit if the
vehicle performance is not correct (the engine does not start with gear in neutral).
•
Indication on the instrument panel always gear in neutral: disconnect the terminals from the
sensor and check if there is continuity with ground connection at PIN toward the sensor, with
gear engaged: if there is continuity, replace the sensor. If it is insulated from the ground
connection, it means that the green/black cable from sensor PIN 1 to ENGINE connector
PIN 16 is short circuited to ground: restore the cable harness
Clutch lever sensor

•
on the vehicle: under clutch lever
•
connector: on the sensor
