B1424

DTC B1424/24 Solar Sensor Circuit (Driver Side)

DESCRIPTION

DTC Detecting Condition:

The automatic light control sensor is installed in the upper part of the instrument panel to detect the amount of solar sensor radiation with photo diode to control the heater and air conditioner "AUTO" function. It sends appropriate signals to the A/C amplifier assembly. The output voltage of the automatic light control 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 assembly reads voltage output from the automatic light control sensor.

HINT: If DTC B1244 is output at the same time, troubleshoot DTC B1244 first.
