Hyundai Santa Fe: Auto Light Sensor. Repair procedures
Inspection
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.
If IGN1 ON, The BCM monitors the range of this supply and
raises up a failure 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.
