continuity of the wiring is necessary for correct activation: no error indications are displayed in case of
lack of activation
DIAGNOSIS INSTRUMENT: ELECTRICAL ERRORS
fuel pump relay control P0230
•
shorted to positive / open circuit, shorted to negative.
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 73 of the VEHICLE con-
nector. If the circuit is open, shorted to negative: voltage equal to zero has been detected
at PIN 73 of the VEHICLE connector.
Troubleshooting
•
If shorted to positive: check whether the relay electrical specifications are correct by dis-
connecting it from the cable harness. If are not OK, replace the relay; if OK, restore the cable
harness (brown/black cable).
•
If the circuit is open, shorted to negative: check the relay electrical characteristics are correct
by disconnecting it from the cable harness; if it is not OK, replace the relay, if it is OK, check
relay connector, engine-vehicle cable harness connector and VEHICLE connector of the
Marelli control unit: if not OK, restore; if OK, check continuity of cable harness (brown/black
cable)
