DIAGNOSTICS INSTRUMENT: ELECTRICAL ERRORS
Gear sensor P0461
•
shorted to positive or open circuit / shorted to negative.
Error cause
•
If the circuit is open, shorted to positive: excessive voltage has been detected at PIN 72. If
shorted to negative: voltage equal to zero has been detected at PIN 72.
Troubleshooting
•
If the circuit is open, shorted to positive: the error is detected with gear engaged only. Check
the sensor connector and the VEHICLE connector of the control unit: if not OK, restore; if
they are OK, check the continuity of the Grey/Black cable between the two connectors: if
not OK, restore; if they are OK, with key set to ON and control unit connector disconnected,
check from the control unit side if the cable is in voltage: if it is in voltage, disconnect the
sensor connector and check if the cable is in voltage: if it is in voltage, restore the cable
harness; if it is not in voltage, replace the sensor (there is an interruption or shorted to positive
of the Pink/Black cable in the section from the sensor connector to the sensor or inside the
sensor).
•
If shorted to negative: disconnect the sensor connector and with key set to ON, check Grey/
Black cable voltage: if equal to zero, restore the cable harness; if equal to approx. 5 V,
replace the sensor (there is short circuit to ground of the Pink/Black cable in the section from
the sensor connector to the sensor or inside the sensor).
Side stand sensor
Function
It tells the side stand position to the control unit.
Operation / Operating principle
If the gear is engaged and the side stand is unfol-
ded, and therefore the circuit is open, the control
unit does not enable vehicle start-up or shuts off
the engine if it is rotating.
Level in electrical circuit diagram:
Start-up enabling switches
Location:
•
on the vehicle: on the stand
•
connector: on the alternator cover (2-
way connector)
