Step
7 Wire circuit check
1) Disconnect radiator cooling fan motor No.1 connector
with ignition switch turned OFF.
2) Measure resistance between "BLU/YEL" wire terminal of
radiator cooling fan relay No.2 connector and vehicle
body ground.
Is resistance infinity?
8 Wire circuit check
1) Measure voltage between "BLU/YEL" wire terminal of
radiator cooling fan relay No.2 connector and vehicle
body ground with ignition switch turned ON.
Is voltage 0 V?
9 Wire circuit check
1) Measure resistance between "BLU/YEL" wire terminal of
radiator cooling fan relay No.2 connector and radiator
cooling fan motor No.1 connector with ignition switch
turned OFF.
Is resistance below 5
10 Radiator cooling fan control check
1) Disconnect connector from radiator cooling fan motor
No.2 and connect radiator cooling fan relay No.2 with
ignition switch turned OFF.
2) Run engine until ECT is over 97.5 °C, 207.5 °F.
3) Measure voltage between "BLU" wire terminals of
radiator cooling fan motor No.2 connector and vehicle
body ground.
Is voltage 10 – 14 V?
11 Wire circuit check
1) Disconnect radiator cooling fan relay No.2 with ignition
switch turned OFF.
2) Measure resistance between "BLU" wire terminal of
radiator cooling fan relay No.2 connector and vehicle
body ground.
Is resistance infinity?
12 Wire circuit check
1) Measure voltage between "BLU" wire terminal of radiator
cooling fan relay No.2 connector and vehicle body
ground with ignition switch turned ON.
Is voltage 0 V?
13 Wire circuit check
1) Measure resistance between "BLU" wire terminals of
radiator cooling fan relay No.2 connector and radiator
cooling fan motor No.2 connector with ignition switch
turned OFF.
Is resistance below 3
14 Wire circuit check
1) Measure resistance between "BLK" wire terminal of
radiator cooling fan motor No.2 connector and vehicle
body ground with ignition switch turned OFF.
Is resistance below 3
