1. SEAT BELT WARNING SYSTEM
WHEN THE IGNITION SW IS TURNED ON, CURRENT FLOWS FROM THE GAUGE FUSE TO TERMINAL 2 OF THE SEAT BELT WARNING
RELAY. AT THE SAME TIME, CURRENT FLOWS TO TERMINAL 5 THROUGH THE SEAT BELT WARNING LIGHT. THIS CURRENT
ACTIVATES THE SEAT BELT WARNING RELAY AND CURRENT FLOWS FROM TERMINAL 2 RELAY TERMINAL 4 GROUND, AND
THE CURRENT WHICH HAS FLOWED THROUGH THE SEAT BELT WARNING LIGHT FOR APPROX. 4–8 SECONDS FLOWS FROM
TERMINAL 5 OF THE RELAY TERMINAL 6 GROUND, CAUSING THE WARNING LIGHT TO LIGHT UP. AT THE SAME TIME AS THE
SEAT BELT WARNING LIGHT LIGHTS UP, THE CURRENT APPLIED TO TERMINAL 2 FLOWS THROUGH THE RELAY TO TERMINAL 6
BUCKLE SW GROUND, CAUSING THE SEAT BELT WARNING BUZZER TO SOUND FOR ABOUT 4–8 SECONDS. HOWEVER, IF THE
SEAT BELT IS PUT ON (BUCKLE SW OFF) DURING THIS PERIOD, THEN THE BUZZER WILL STOP.
