Kia Carens: Auto Lighting Control System / Auto Light Sensor Repair procedures
In the state of IGN1 ON, when the multi function switch module detects auto
light switch on, tail lamp relay output and head lamp low relay output are controlled
according to auto light sensor's input.

as soon as the supply’s voltage is out of range. Then this failure occurs
and as long as this is present, the head lamp must be turned on without taking
care about the sunlight level provided by the sensor.
This is designed to prevent any head lamp cut off when the failure occurs during
the night.
