SEAT BELT WARNING SYSTEM
When the ignition SW is turned on, the current flows from the GAUGE Fuse to comb. Meter TERMINAL (B) 10. At this time, to determine whether the
driver is wearing the seat belt or not, a signal is input from the buckle SW (Driver side) to comb. Meter TERMINAL (A) 12. If the driver is not wearing
the seat belt, the seat belt warning light in the comb. Meter flashes and buzzer to inform the driver. Also, a sensor installed in the front passenger seat
determines whether there is a passenger seated, and whether the seat belt is worn or not. If the seat belt is not worn, the signal from the buckle SW
(Passenger side) and the sensor is input to the comb. Meter TERMINAL (B) 15, and the current flows from comb. Meter TERMINAL (A) 20 to
passenger seat belt warning light TERMINAL 9 to TERMINAL 4 to GROUND, and the light flashes to inform.
