Hyundai Sonata: Auto Lighting Control System / Auto Light Sensor Repair procedures
Hyundai Sonata LF 2014-2019 Service Manual / Body Electrical System / Auto Lighting Control System / Auto Light Sensor Repair procedures
| Inspection |
Check if the auto light control operates like a timing chart
shown below. Tail lamp output and head lamp (Low) output is controlled
based on the auto light sensor's input (illumination intensity) when the
Auto Light Switch in Multi-Function Switch is turned ON, and the
vehicle is in IGN1 or IGN2 ON Mode. If IGN1 = ON, BCM detects this
voltage, and if the voltage exceeds rated voltage, then auto light
failure occurs. (below 4V or above 6V)
Failure Occurrence: If auto light failure occurs, the head
lamp must be turned ON regardless of sun light level. This is to prevent
the head lamp from being turned OFF in case of auto light failure
during night time. |
In the state of IGN1 ON, when 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.The
auto light control doesn't work if the pin sunlight supply (5V regulated
power from Ignition 1 power to sunlight sensor) is in short circuit
with the ground.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.
