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 IPM
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.
