System Outline
Current always flows to TERMINAL 1 to the integration relay through the DOME fuse.
1. SEAT BELT WARNING SYSTEM
When the ignition SW is turned ON, current flows from the GAUGEfuse to TERMINAL 7 of the integration relay. At the same time, current
flows to TERMINAL 9 of the integration relay from the GAUGE fuse through the seat belt warning light. Then, if the driver's seat belt is not
fastened (A retractor SW OFF signal is input to TERMINAL 8 of the integration relay), the current flowing through the warning light flows from
TERMINAL 9 of the integration relay to TERMINAL 10 to GROUND, and lights up the warning light. The current flowing to TERMINAL 1
of the integration relay also flows from TERMINAL 10 to GROUND and the seat belt warning buzzer sounds for approx. 6 seconds. However, if
the seat belt is put on during this period (While the buzzer is sounding), signal input to TERMINAL 8 of the integration relay stops, and the
current flowing from TERMINAL 1 to the integration relay to TERMINAL 10 to GROUND is cut, causing the buzzer to stop.
2. KEY REMINDER SYSTEM
With the ignition key inserted in the key cylinder (Unlock warning SW ON), the ignition SW still OFF and driver's door open (Door courtesy SW
ON), when a signal is input to TERMINAL 6 of the integration relay, the integration relay operates, the current flows from TERMINAL 1 of the
integration relay to TERMINAL 10 to GROUND and the key reminder buzzer sounds.
