COOLING FAN
Description
INFOID:0000000001094292
Cooling fan operates at each speed when the current flows in the cooling fan motor as follows.
Refer to
for cooling fan operation.
Component Function Check
INFOID:0000000001094293
1.
CHECK COOLING FAN LOW SPEED FUNCTION
With CONSULT-III
1.
Turn ignition switch ON.
2.
Perform “COOLING FAN” in “ACTIVE TEST” mode with CONSULT-III and touch “LOW” on the CON-
SULT-III screen.
3.
Make sure that cooling fans operates at low speed.
Without CONSULT-III
1.
Start engine and let it idle.
2.
Turn air conditioner switch and blower fan switch ON.
3.
Make sure that cooling fan operates at low speed.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Check cooling fan low speed control circuit.
2.
CHECK COOLING FAN HIGH SPEED FUNCTION
With CONSULT-III
1.
Touch “HI” on the CONSULT-III screen.
2.
Make sure that cooling fans operates at higher speed than low speed.
Without CONSULT-III
1.
Turn ignition switch OFF.
2.
Turn air conditioner switch and blower fan switch OFF.
3.
Disconnect engine coolant temperature sensor harness connector.
4.
