IGNITION KEY REMINDER TIMER FUNCTION
LJ
(1) While the ignition key is inserted in the ignition
switch (key reminder switch OFF), the H signal
of the key reminder switch is input to
ANDs.
(2) If either front door is open (door switch ON)
at that time, the L signal from the door switch
is reversed to the H signal by NOT and applied
to
AND3.
(3) As a result,
AND3
outputs the H signal and
inputs it to
AND2.
(4) If the inside lock knob of the driver’s door is
pushed forward at that time (the door lock actua-
tor LOCK), the H signal from the door lock actua-
tor is applied to
AND2.
(5) As a result,
AND2
outputs the H signal, which
is input to the timer circuit through OR to operate
the timer circuit, turn ON the transistor Tr for
five seconds, and unlock all doors.
(6) If the front passenger’s door is opened and
the inside lock knob is pushed forward (door
lock actuator LOCK) while the ignition key is
inserted in the ignition switch (key reminder
switch OFF) and the driver’s door is locked (door
lockactuator LOCK),
AND,
outputs the H signal.
The signal is input to the timer circuit through
OR to operate the timer circuit, turning ON the
transistor Tr for five seconds and unlocks all
doors.
