tion manual for further details.)
2) Start the engine and run it idling condition.
3) Click "Cooling fan relay control" 1.
4) Click the "Operate" 2.
At this time, if an operation sound is heard from the cooling fan relay and cooling fan motor is operated,
the function is normal.
NOTE:
The cooling fan relay and cooling fan motor inspection is operational at any engine coolant temperature until
reaching 100 °C (212 °F).
5) Click the "Stop" 3 to check the operation properly.
6) Click the "Off" 4 to check the cooling fan relay and cooling fan motor operation.
NOTE:
* This inspection should be begun from when the engine coolant temperature is below 50 °C (122 °F).
Check that the cooling fan relay operates for a few seconds as the engine coolant temperature reaches
each temp. of 50 °C (122 °F), 70 °C (158 °F) and 90 °C (194 °F)/above 4 000 r/min. It is cooling fan motor
malfunction or its circuit failure when the motor would not run even if the relay turns ON.
* There is a tolerance of operating temperature of cooling fan relay.
