•
If the sensor resistance is not OK replace the sensor.
•
If OK check, with the key turned ON, for the presence of voltage at sensor connector PIN
1:
•
If there is no voltage at PIN 1 replace the instrument panel.
•
If about 12 V is present, restore the cabling (there is a short to battery).
•
If about 5 V is present, connect a 10 kOhm resistance to PIN 1 of the sensor connector and
the vehicle ground.
•
If, with the key ON, the voltage measured upstream of the resistance drops, replace the
instrument panel. If it continues to stay at about 5 V restore the pink cable (there is a short
to + 5V).
•
In case there is a short circuit to ground connection of PIN 12 of the instrument panel con-
nector:
•
Check the ground insulation of the sensor connector pink cable:
•
If connected to ground, restore the cabling. If insulated from ground, check correct resistance
of the sensor:
•
if not OK, replace the sensor; if OK, replace the instrument panel
RUN/STOP switch
Function
It tells the control unit if the rider wishes to enable
engine start-up or to keep the engine running.
Operation / Operating principle
If the driver wants to shut off the engine or to dis-
able engine start-up, the switch should be open,
i.e. the Marelli control unit should not detect volt-
age at PIN 26 of the control unit connector.
