Automatic Light Control Sensor
WARNING: This page is about a different car, the 2002 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
This procedure should be performed ONLY after the multiplex communication system has been diagnosed and DTC B1244/44 requires sensitivity adjustment of the automatic light control sensor.
If headlights illuminate too early, turn sensitivity knob on automatic light control sensor counterclockwise. If headlights illuminate too late, turn sensitivity knob on automatic light control sensor clockwise. See Fig 1.
