CHECK the identification of the relay
with the colour of the cables). Electrical
continuity is required in the wiring for
the relay to activate correctly: no errors
are generated if the relay fails to acti-
vate
CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING,
CAREFULLY READ THE GENERAL TROUBLESHOOTING
CONCEPTS FOR ELECTRICAL DEVICES AT THE BEGIN-
NING OF THE CHECK AND CONTROL SECTION IN THE
ELECTRICAL SYSTEM CHAPTER.
DIAGNOSTIC TOOL: ELECTRICAL ERRORS
P0480 Cooling fan command
Electrical diagnosis:
•
short circuit to positive/ short circuit to negative / open circuit
Error cause:
•
Short-circuit to positive: excessive voltage has been detected at PIN 61 of the VEHICLE
connector.
•
If short circuit to negative: no voltage has been detected.
•
If open circuit: 5V voltage has been detected. Error recognition carries out only when the
fan relay is activated.
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
cable)
•
If short circuit to negative: check the relay electrical specifications are correct by discon-
necting it from the cable harness. If not OK, replace the relay; if OK, restore the cable harness
(Brown cable)
•
If open circuit: 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 cable)
