MODE DOOR ACTUACTOR

MODE DOOR ACTUATOR is located side of the heater unit.

SENSORS

FIN THERMO SENSOR

1. Description

Fin sensor is installed in the evaporator in order to detect the temperature of evaporator. It prevents evaporator from freezing.

Location

: Inserted into the evaporator pin

Characteristics

2-2. On/off temperatures:

0 ~ 0.5°C : OFF

3.5 ~ 4°C : ON

INCAR SENSOR

The in-car sensor is located on the lower crash pad as shown in the picture. It contains a thermister, which measures the temperature of the air inside the passenger compartment. It senses the passenger compartment temperature, changes the resistance value, and enters the corresponding voltage into the automatic temperature control module (FATC).

Inspection

Negative type thermistor, that resistance will rise with lower temperature, and reduce with higher temperature.

PHOTO SENSOR

The photo sensor is located by the driver side defrost nozzle. In response to photo intensity level in vehicle, the sensor will send signal to control module to control the blower level and discharge temperature.

It contains a photovoltaic (sensitive to sunlight) diode.

AMBIENT SENSOR

The ambient temperature sensor is located at the front of the condenser fan shroud. This sensor detects the temperature of outside air and sends voltage signals to the controller.

The sensor output will be used for discharge air temperature, sensor fail-safe, temperature door control, blower motor level control, mix mode control and in-car humidity control.

It is a negative type thermistor; resistance will increase with lower temperature, and decrease with higher temperatures

AQS (Air Quality System)

Most drivers generally select the recirculation or fresh air mode manually to intercept the inflow of harmful exhaust gas, in spite of inconvenience and danger, while driving. These harmful gases can be causes of tiredness, drowsiness or cough while driving.

Although they detect the exhaust gas and manually close the inlet of the vehicles trapping the fumes inside, it is far too late to protect their health because they already inhaled the exhaust gas. Inversely, if driving with the inlet of the car closed completely, the shortage of air and the accumulation of carbon dioxide (CO2) will be occurred. This causes fatigue, headache, enervation, and drowsiness.

AQS gives a perfect solution to these problems. The Air Quality System detects exhaust gas of neighboring vehicles and intercepts automatically. AQS controls the inlet of car automatically and can be easily installed to the existing vehicle. Manual operation is also available.

Location

The AQS is located at the front of the engine radiator.

HUMIDITY SENSOR

Humidity sensor detects the relative humidity of the car’s cabin. This sensor converts it into the frequency signal (Hz) and sends the signal to the FATC controller. If ambient air temperature or in-car humidity is outside certain range, it will turn on A/C to control in-car humidity preventing in-car fogging.
