MOTO GUZZI NEVADA Service Station Manual page 86

Electrical system
3. Engine speed sensor anti-jamming cable
(blue/green cable)
PARAMETERS
Target engine revs
Example value:1100 +/- 100 rpm
Parameter valid at idle, setting depends especially on engine temperature: the ECU unit will try to keep
the engine running at this revs, acting on the ignition advance.
STATUSES
Synchronisation
Example value:Synchronised / Not synchronised
Indicates if the control unit detects the engine speed sensor signal correctly
ELECTRICAL ERRORS
Cause
Faulty cabling or pick up
Troubleshooting
•
An interruption in the sensor circuit has been detected, from PIN 20 to PIN 29 of the control
unit connector.
•
Check the sensor connector and the injection ECU connector:
•
If the values are incorrect restore them.
•
If the values are correct, check the continuity of the two cables that go from PIN 20 to PIN
29 of the control unit connector:
•
If there is no continuity, restore the cabling.
•
If there is continuity check interruption in the sensor and replace it.
Short circuit.
•
Conduct an electrical check of the sensor.
•
If the sensor check value is incorrect replace it.
•
If the value is correct, check insulation of the power from ground of the two cables.
•
Conduct tests from the sensor connector toward the sensor.
•
If the sensor value is incorrect restore the cabling/replace the sensor.
•
If the value is correct conduct tests from PIN 20 and 29 of the Marelli control unit connector
toward the cable harness.
