Seat Belt Reminder Buzzer: Description and Operation
System Outline
Current always flows to TERMINAL 3 of 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 the TERMINAL 9 of the integration relay at the same time, current
flows to TERMINAL 10 of the relay from the gauge fuse through the seat belt warning light. This current activates the seat belt warning relay
and. current flowing through the warning light flows from TERMINAL 10 of the relay --> TERMINAL 7 --> GROUND, causing the warning
light to light up. at the same as the warning light lights up. a buckle SW OFF signal is input to TERMINAL 5 of the relay, the current flowing to
TERMINAL 1 of the relay flows from TERMINAL 7 --> GROUND and the seat belt warning buzzer sounds for approx. 4-8 Seconds.
However, if seat belt is put ON during this period
(While the buzzer is sounding), signal input to TERMINAL 5 of the relay stops an the current flow from TERMINAL 1 of the relay -->
TERMINAL 7 --> GROUND is cut, causing the buzzer to stop.
2. UNLOCK WARNING SYSTEM
With the ignition key inserted in the key cylinder (unlock warning SW ON), the ignition SW still OFF and door open (door courtesy SW ON),
when a signal is input TERMINALS 4 and 8 of the relay. the integration relay operates, current flows from TERMINAL 1 of the relay -->
TERMINAL 7 --> GROUND and the unlock warning buzzer sounds.
