Seat Belt Reminder Buzzer: Description and Operation

^ Current always flows to TERMINAL 1 of the integration relay through DOME fuse.

1. SEAT BELT WARMING 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 flowing through the warning light flows from TERMINAL 9 of the relay --> TERMINAL 10 --> GROUND, causing the warning light to light up. At the sane time as the warning light lights up, a buckle SW OFF signal is input to TERMINAL 8 of the relay, the current flowing to TERMINAL 7 of the relay flows from TERMINAL 10 --> 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 relay stops and the current flow from TERMINAL 7 of the relay --> TERMINAL 10 --> GROUND is cut, causing the buzzer to stop.

2. UNLOCK WARNING SYSTEM
With the Ignition key inserted in the key cylinder (unlock SW ON), the Ignition SW still OFF and door open (door open detection 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 --> TERMINAL 10 --> GROUND and unlock warning buzzer sounds.
