udgement circuit, and when the key cylinder switch
ON signal is input, an H signal is input to the lock
output side of timer circuit I. This causes Tr2 to turn
ON for 0.5 seconds, and all of the doors lock. Also,
if the passenger's side door is unlocked by means o
the key, an L signal is input to the door lock switch
udgement circuit, and when a key cylinder switch
ON signal is input, an H signal is input to the unlock
side of timer circuit I. This causes Tr1 to turn ON for
0.5 seconds, and all of the doors unlock.

OPERATION
CENTRAL DOOR LOCKING
(1) When the inside lock knob on the driver's side is
locked, AND1 outputs an H signal which causes Tr2
to turn ON for 0.5 seconds by means of timer circuit
I, and all of the doors lock. In addition, when the
inside lock knob on the driver's side is unlocked, the
L signal is reversed by the NOT1 and a H signal is
input to the unlock output side of timer circuit I. This
causes Tr1 to turn on for 0.5 seconds, and all of the
doors unlock.
(2) When the driver's side door is locked by means o
the key, the operation is the same as in step (1).
(3) If the passenger's side door is locked by means o
the key, an H signal is input to the door lock switch
PREVENTING DOORS FROM BEING LOCKED WHEN IGNITION KEY IS LEFT BEHIND
If the key is left in the ignition switch (key reminder
switch OFF), when the driver's side door is opened
(door switch ON) and the driver's side inside lock
knob is locked, AND3 and AND2 output H signals.
This causes timer circuit II to operate to turn Tr1
ON, and all of the doors unlock to prevent the key
from being left behind.
