Supra L6-2997cc 3.0L DOHC MFI (1998)
Seat Belt Reminder Buzzer: Description and Operation
Current always flows to TERMINAL 1 of the integration relay through 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 integration 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 integration 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 integration relay, the current flowing to TERMINAL 7 of
the integration relay flows through 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 integration relay stops and the current
flow from TERMINAL 7 of 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 LH door open (Door courtesy SW ON
), when a signal is input to TERMINAL 6 of the integration relay, the integration relay operates, current flows from TERMINAL 7 of the
integration relay to TERMINAL 10 to GROUND and key reminder buzzer sounds.
