Auto Light Sensor

Repair procedures


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.



1. Disconnect the negative (-) battery terminal.

2. Remove the photo & auto light sensor (A) from crash pad upper side by using a flat-up screwdriver.

3. Remove the auto light sensor connector.

3. Remove the auto light sensor connector.


1. Reconnect the auto light sensor connector.

2. Install the auto light sensor.
