Precautions: Precautions for Diagnosing Trouble · General safety (00)
•In the automatic air conditioning system (auto A/C), HVAC control module automatically controls inside air temperature, blower fan speed, air inlet and outlet, etc. Once users set desired inside air temperature with the temperature control selector and push “AUTO” switch, HVAC control module starts detecting the inside air temperature, the outside air temperature, sunlight and the engine coolant temperature by means of the inside air temperature sensor, the outside air temperature sensor, the sunload sensor, and the ECT sensor, respectively. In this way, HVAC control module keeps in-car temperature at the desired level at all times.
