COOLING FAN OPERATION WITH THE ENGINE RUNNING
The cooling fan motor is controlled:

temperature sensor malfunction, and is switched off when the temperature falls below 93 °C(199°F).
at high speed if the engine coolant temperature exceeds 99 °C(210°F) or if there is a low speed malfunc-
tion, and is switched off when the temperature falls below 96 °C(205°F).
The cooling fan motor low and high speeds are controlled when the air conditioning function is selected on the
