6) Click the off button (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
arrives each at 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 to ON.
• There is a tolerance of operating temperature of cooling fan relay.
