DTC P0480: Fan 1 (Radiator Cooling Fan) Control CircuitS7RS0B1104050
Wiring Diagram5
Wire circuit check
1) Connect connector to purge control valve with ignition
switch turned OFF.
2) Turn ON ignition switch and measure voltage between “C37-29” terminal of ECM connector and vehicle body
ground.
Is it voltage 10 – 14 V? Go to Step 6. “BLU/BLK” wire is open
circuit.
6 EVAP canister purge control valve check
1) Check EVAP canister purge control valve referring to
“EVAP Canister Purge Valve Inspection in Section 1B”.
Is it in good condition? Go to Step 7. Faulty EVAP canister
purge control valve.
7 EVAP canister purge control circuit check
1) With ignition switch turn OFF, measure resistance
between “E23-1/16” terminal and “C37-29” terminal of
ECM connector.
Is resistance below 40
Ω at 20 °C, 68 °F? Faulty ECM. Substitute
a known-good ECM and
recheck.
“BLK/RED” and/or
“BLU/BLK” wire are high
resistance circuit.

Wiring Diagram12
Wire circuit check
1) Disconnect radiator cooling fan control relay No. 2 and
No. 3 from individual circuit fuse box No.1 with ignition
switch turned OFF.
2) Measure resistance between “E23-48” terminal of ECM connector and vehicle body ground.
Is resistance infinity? Go to Step 13. “GRN” wire is shorted to
ground circuit.
13 Wire circuit check
1) Turn ON ignition switch.
2) Measure voltage between “E23-48” terminal of ECM
connector and vehicle body ground.
Is voltage 0 V? Go to Step 14. “GRN” wire is shorted to
power supply circuit.
14 Radiator cooling fan relay No. 2 and No. 3 check
1) Check radiator cooling fan relay No. 2 and No. 3
referring to “Radiator Coolin g Fan Relay Inspection in
Section 1F”.
Are relays in good condition? “GRN” wire is open
circuit.
Replace relay.
15 Radiator cooling fan control No. 2 and No. 3 check
1) Connect connectors to ECM with ignition switch turned
OFF.
2) Connect radiator cooling fan relay No. 2 to individual circuit fuse box No.1.
3) Run engine until ECT is over 102.5 °C, 216.5 °F.
4) Measure voltage between vehicle body ground and “E23-48” terminal of ECM connector.
Is voltage lower than 1.5 V? Intermittent trouble.
Check for intermittent
refer to “Intermittent and
Poor Connection
Inspection in Section
00”.
If OK, substitute a
known-good ECM and
recheck.
Faulty ECM.
