Seat Belt Reminder Buzzer: Description and Operation
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
the current flowing 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, the current flowing to TERMINAL 1 of the relay 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 relay stops and the current flow from TERMINAL 1 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 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 relay, the integration relay operates, current flows from TERMINAL 1 of the relay to
TERMINAL 10 to GROUND and key reminder buzzer sounds.
