Wiring Diagram
11 Check wire circuit
1) Disconnect radiator fan control relay No.2 and No.3 from
relay box.
2) Measure resistance between “G04-3” terminal wire and
vehicle body ground.
Is resistance infinity?
Go to Step 12. “GRN/RED” wire
shorted to ground
circuit.
12 Check wire circuit
1) Turn ON ignition switch.
2) Check voltage between “G04-3” terminal wire and
vehicle body ground.
Is voltage 0 V?
Go to Step 13. “GRN/RED” wire
shorted to power supply
circuit.
13 Check radiator fan control relay No.2 and No.3
1) Check radiator fan control relay No.2 and No.3, referring
to “Radiator Fan Relay No.1, No.2 and No.3 Inspection

1) Connect connectors to ECM with ignition switch turned
OFF.
2) Run engine at ECT is over 107
°
C, 225
°
F.
3) Measure voltage between vehicle body ground and
“G04-3” terminal wire.
Is voltage lower 1.5 V?
Radiator cooling fan
control system is good
condition.
Repeat “DTC
