Fuel pump
NOTES: The injection relay (No 33 in the wiring diagram, position under the saddle, next to the battery
positive, CHECK, however, the identification of the relay with the colour of the cables) is energised for
30 seconds. Electrical continuity is required in the wiring for the relay to activate correctly: no errors are
generated if the relay fails to activate
DIAGNOSTIC TOOL: ELECTRICAL ERRORS
Fuel pump relay command P0230
•
short circuit to positive/ open circuit, short circuit to negative.
Error cause
•
Short-circuit to positive: excessive voltage has been detected at PIN 73 of the VEHICLE
connector. If open circuit, short circuit to negative: a voltage equal to zero was detected at
PIN 73 of the ENGINE connector.
Troubleshooting
•
Short-circuit to positive: check the relay electrical specifications are correct by disconnecting
it from the cable harness. If not OK, replace the relay; if OK, restore the cable harness
(Brown/Black cable).
•
If open circuit, short circuit 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).
