For USA

Power is supplied at all times
^ to headlamp relay terminal (1), and
^ through 15 A fuse [No. [53], located in the fuse, fusible link and relay box]
^ to headlamp relay terminal (5), and
^ through 15 A fuse [No. [54], located in the fuse, fusible link and relay box]
^ to headlamp relay terminal (7), and
^ through 7.5 A fuse [No. [14], located in the fuse block (J/B)].
^ to BCM terminal (105).
When the ignition switch is in the ON or START position, power is supplied
^ through 7.5 A fuse [No. [32], located in the fuse block (J/B)]
^ to BCM terminal (68).
Ground is supplied
^ to BCM terminals (56) and (113)
^ to illumination time control switch terminal (3)
^ through body grounds (M14) and (M47), and
^ to the lighting switch terminals (8) and (5)
^ through body grounds (E22) and (E36).

Low beam operation
When the lighting switch is turned to 2ND and LOW ("B") positions, ground is supplied
^ to headlamp relay terminal (2)
^ from the lighting switch terminal (12).
Headlamp relay is then energized, and power is supplied
^ from the headlamp relay terminal (6)
^ to terminal (2) of the LH headlamp, and
^ from the headlamp relay terminal (3)
^ to terminal (2) of the RH headlamp.
Ground is supplied
^ to terminal (1) of the LH headlamp
^ from the lighting switch terminal (7) , and
^ to terminal (1) of the RH headlamp
^ from the lighting switch terminal (10).
With power and ground supplied, the low beam headlamps illuminate.

High beam operation/flash-to-pass operation
When the lighting switch is turned to 2ND and HIGH ("A") or PASS ("C") positions, ground is supplied
^ to headlamp relay terminal (2)
^ from the lighting switch terminal (12).
Headlamp relay is then energized, and power is supplied
^ from the headlamp relay terminal (6)
^ to terminal (2) of the LH headlamp, and
^ to combination meter terminal (34) for the HIGH BEAM indicator
^ from headlamp relay terminal (3)
^ to terminal (2) of the RH headlamp.
Ground is supplied
^ to terminal (3) of the LH headlamp, and
^ to combination meter terminal (33)
^ from the lighting switch terminal (6)
^ to terminal (3) of the RH headlamp
^ from the lighting switch terminal (9)
With power and ground supplied, the high beam headlamps illuminate.

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 headlamp relay terminal (2)
^ from the BCM terminal (5).
Headlamp relay is then energized, and headlamps (Low or High) illuminate according to switch position Auto light operation allows headlamps to turn off when outside is brighter than the prescribed level. Or the ignition switch is turned to OFF position. (When shut oft delay function is canceled.)
For parking, license and tail lamp auto operation, refer to "PARKING, LICENSE AND TAIL LAMPS".

SHUT OFF DELAY
While the headlamps are lit in the auto-light operation mode, the ignition switch is turned from the "ON" to the "OFF" position. The BCM no longer receives a voltage signal at terminal (68). This starts the auto light shut off delay timer. The timer is set based on the resistance value at BCM terminal (57). With the timer running, the headlamps remain lit. When the timer reaches the end of its cycle, the head lamps turn off. Headlamp lighting time can be adjusted from about 0 to 3 minutes. (This function is not applicable to the tail lamps.)

THEFT WARNING SYSTEM
The theft warning system will flash the high beams if the system is triggered. Refer to "THEFT WARNING SYSTEM - IVMS".
