ignition switch in the OFF or ACC position, the
H signals of the key reminder switch and the
ignition switch inverted by
NOT1
are input to
by
NOT2
and the H signal output from
AND1
are input to
AND2.
Then
AND2
outputs H signal
to cause the detector circuit to operate.
3.
ANDi.
As a result,
AND1
outputs H signal.
The buzzer output causes the transistor to be
2.
When the driver’s door is opened (door switch
alternately ON and OFF, and the buzzer sounds
ON), the H signal of the door switch inverted
intermittently to remind the driver that the ignition
