•
Short-circuit to positive: excessive voltage has been detected on VEHICLE PIN 68. If short
circuit to negative: no voltage has been detected. If open circuit: an interruption has been
detected
Troubleshooting
•
Short-circuit to positive: disconnect the injector connector, set key to ON, activate the com-
ponent with the diagnostic tool and check the voltage on the White/Blue cable on the injector
connector: if there is voltage, restore the filter box cable harness. If there is no voltage,
replace the sensor
•
If short circuit to negative: disconnect the injector connector, set the key to ON and check if
there is a ground connection on the white/blue cable: if the connection is present, restore
the cable harness. If there is no connection, replace the injector
•
If open circuit: check the component correct electrical characteristic: if it is not the correct
one, replace the component; if it is correct, check the connector on the component and the
Marelli control unit connector: if not OK, restore. If OK, check cable continuity between VE-
HICLE PIN 68 and component PIN - and restore the cable harness
Fuel pump
Function
Fuel pump: keeps pressure of the injectors supply
duct.
Low fuel: tells to the instrument panel about low
fuel
Operation / Operating principle
Low fuel: it is a resistance that if correctly supplied
varies its electrical resistance if it is damped or not
by petrol.
Level in electrical circuit diagram:
Injection load relay
Location:
•
on the vehicle: on the tank.
•
connector: on right rear frame (4-ways
black).
Electrical characteristics:
PIN 1-2: 0.5 - 1 ohm; PIN 3-4: you do not need to
measure the component electrical resistance
since it works correctly with suitable supply from
the instrument panel only. Check correct operation
