4) Click the "Operate" (2).
At this time, if an operation sound is heard from the cooling fan relay and cooling fan motors are 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). In a hot engine condition with the intake air temperature
exceeding 40 °C (104 °F), however, the engine coolant temperature at which the inspection is
operational will be restricted to 95 °C (203 °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
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 ON.
• There is a tolerance of operating temperature of cooling fan relay.
