Air Conditioning System (for Automatic Air Conditioning System)

DTC 21 SOLAR SENSOR CIRCUIT (PASSENGER SIDE)

CIRCUIT DESCRIPTION

Detection Item:

The A/C solar sensor is installed in the upper part of the instrument panel to detect the amount of solar sensor radiation with photodiode to control the heater and air conditioner "AUTO" function. It sends appropriate signals to the A/C amplifier. The output voltage of the A/C solar sensor changes in accordance with the amount of solar radiation. As the amount increases, the voltage increases. As the amount decreases, the voltage decreases. The A/C amplifier reads voltage output from the A/C solar sensor.
