Auto Light Operation

BCM is connected to the optical sensor. The optical sensor sends a signal to BCM according to outside brightness.

When the lighting switch is turned to AUTO position, ground is supplied

• to BCM terminal (14)
• from the lighting switch terminal (42).

When ignition switch is set to ON or START and outside is darker than the prescribed level, ground is supplied

• to tail lamp relay terminal (2)
• from the BCM terminal (11).

Tail lamp relay is then energized, and parking, license and tail lamps illuminate.

Auto light operation allows these lamps to turn off when outside is brighter than the prescribed level.

Or the ignition switch is turned to the OFF position.
