System Outline
Current always flows to TERMINAL 1 of the integration relay through the DOME fuse.
1. SEAT BELT WARNING SYSTEM
When the ignition SW is turned ON, current flows from the GAUGE fuse to TERMINAL 7 of the integration relay. At the same time, current
flows to TERMINAL 9 of the relay from the GAUGE fuse through the seat belt warning light. This current activates the integration relay and
current through the warning light flows from TERMINAL 9 of the relay to TERMINAL 10 to GROUND, causing the warning light to light up.
A buckle SW OFF signal is input to TERMINAL 8 of the relay, current to TTERMINAL 7 of the relay flows from TERMINAL 10 to
GROUND and the seat belt warning buzzer sounds for approx. 4-8 seconds. However, if the seat belt is put on during this period (While the
buzzer is sounding), signal input to TERMINAL 8 of the relay stops and the current flowing from TERMINAL 7 of the relay to TERMINAL 10
to GROUND is cut, causing the buzzer to stop.
2. KEY REMINDER SYSTEM
With the ignition key inserted in the ignition key cylinder (Unlock SW ON), the ignition SW still OFF and the driver's door open (Door courtesy
SW ON), when a signal is input to TERMINAL 6 of the relay, the integration relay operates, current flows from TERMINAL 7 of the relay to
TERMINAL 10 to GROUND and the key reminder buzzer sounds.
