System Outline

With the ignition SW in ACC position, current flows to TERMINAL 8 of the integration relay. When the ignition SW is turned to ON position, current flows to TERMINAL 6 of the relay. When the light control SW is turned to TAIL or HEAD position, current is applied to TERMINAL 4 of the relay through the TAIL fuse.

LIGHT REMINDER SYSTEM
When the light control SW is in TAIL or HEAD position and the driver's door is opened (Door courtesy SW ON), as a result, the relay is activated and current flows from TERMINAL 4 of the relay to TERMINAL A 5 to TERMINAL 1 of the door courtesy SW LH to GROUND, sounding the light reminder buzzer.
