Replace the cooling fan relay with a new one. |
Active control inspection
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). |
