DTC B1421 Solar Sensor Circuit (Passenger Side)

DESCRIPTION

Detection Condition:

The solar sensor is installed in the upper part of the instrument panel to detect the amount of solar radiation with a photodiode to control the heater and air conditioner "AUTO" function. It sends appropriate signals to the air conditioning amplifier. The output voltage of the 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 air conditioning amplifier reads voltage output from the solar sensor.
