Optical sensor ground is supplied

to optical sensor terminal 3
through BCM (body control module) terminal 18.

When ignition switch is turned to "ON" position and when outside brightness is darker than prescribed level, input is supplied

to BCM terminal 58
from optical sensor terminal 4.

The headlamps will then illuminate. For a description of headlamp operation, refer to "SYSTEM DESCRIPTION ".
