•
An abnormal behaviour of the voltage at PIN 31 of the BLUE connector has been detected:
the voltage, that should vary over time, keeps a constant value instead.
Troubleshooting
•
check circuit continuity of the lambda sensor connector (PIN 1 PIN2) toward the probe:
replace the lambda sensor if there is no continuity; if there is continuity, check the sensor
connector and the Marelli control unit connector: If not OK, restore. If OK, check continuity
between the BLUE connector PIN 31 and PIN 21 and restore the cable harness.
Injector
Function
To supply the correct amount of petrol at the right
timing.
Operation / Operating principle
Injector coil is excited for the petrol passage to
open.

Left injector:
operation for 4 ms, 5 times
The auxiliary injection relay (no. 33 in the wiring diagram, placed under the saddle, left rear relay in the
relay group attached to the fall sensor; CHECK, however, the identification of the relay with the colour
of the cables) is energised for 5 seconds and the grey/red cable of the injector is closed to ground for
4 ms per second. Disconnect the 4-way connector of the fuel pump to be able to hear the relay and
injector activation. The continuity of the wiring is necessary for correct activation: no error indications
are displayed in case of lack of activation
