SYSTEM OUTLINE
1. SEAT BELT WARNING SYSTEM
When the ignition SW turned on, a signal is input to the combination meter. To determine whether the driver has fastened the
seat belt, a signal is input from the buckle SW LH to the combination meter TERMINAL (E) 3. When the seat belt is not
fastened, the seat belt warning light in the combination meter blinks, and emits a warning sound.
In addition, the front passenger is recognized by a sensor (Seat belt warning occupant detection sensor (Buckle SW RH)) is
installed in the front passenger seat, and determines whether the seat belt is fastened. When not fastened, the signals from
the buckle SW RH is input to combination meter TERMINAL (E) 4, and the passenger seat belt warning light blinks to warn
the passenger.
2. KEY REMINDER SYSTEM
When the driver door is opened with the ignition SW off and ignition key remaining in the key cylinder (Unlock warning SW
on), a signal is input from the unlock warning SW to the combination meter TERMINAL (E) 16, and from the door courtesy
SW front LH to combination meter TERMINAL (E) 9. As a result, the buzzer in the combination meter goes on and warns the
driver that the key is remaining in the key cylinder.
