When the doors are locked (by using the inside lock
knobs or the door key), the door lock switch
(incorporated within the door lock actuator) is
switched OFF, and then, because current flows to
the fuse, as well as to the door-control unit and the
lock timer, the lock timer causes base current to
flow to
TrI for 0.5 second, thus switching ON Tr,. As
a result, current flows to the fuse, as well as to the
“lock” side coil of the door lock relay,
Tr,, and to
ground, thus switching ON the “lock” side contacts
of the door lock relay and activating the door lock
actuators, thereby locking the doors.

When the doors are unlocked (by using the inside
lock knobs or the door key), the door lock switch
(incorporated within the door lock actuator) is
switched ON, and then, -because current flows to
the fuse, the door-control unit and the lock timer,
the lock timer causes base current to flow to

0.5 second, thus switching ON
Tr7. As a result,
current flows to the fuse, as well as to the “unlock”
side coil of the door lock relay,

thus switching ON the “unlock” side contacts of the
door lock relay and activating the door lock

1. When the switch is operated, contacts “b” and
“c” at the “DOWN” side are caused to connect.
and current flows from the battery to contact
“b”, contact “c”,the motor, contact “c”‘,
contact “a”‘,
resistor R and to ground, and, as aresult, the motor rotates to the “DOWN” side.
2.Current from contact “b” and contact “c” flows
through diode
DI and R.; then I% and I%, and R,and
R7, cause reference voltage to be applied to
the negative
(-) side of IC and the positive (+)
side of
G. The reference voltage is maintained
at a certain fixed level by the
ZD.3. During the time that the motor is in operation,
the amount of current flowing to the motor is
not very much, and, because the voltage
(ICcomparison voltage) at point A is lower than the
reference voltage at the negative
(-) side of IC,,the output voltage of
IC becomes low. For G,because the voltage
(G comparison voltage) at
the negative
(-) side becomes lower than the
reference voltage at the positive (+) side, the
output voltage of
lC2 becomes high, and the
transistor
(Tr) is switched ON.
4. Because the transistor
(Tr) is switched ON,
current also flows from diode
D1 to the coil (L).thus causing excitation of the coil
IL), with the
result that the switch is held by the plunger.

1. When the glass reaches the lowermost point,
the amount of current flowing to the motor
increases, and the voltage applied at point A also
increases.2. When the voltage
(IC comparison voltage) at
the positive
(+) side of IC becomes higher than
the reference voltage at the negative
(-) side,
the output voltage becomes higher but voltage
is prevented from being applied momentarily to
the negative
I-) side of ICI by resistor R6 and the
capacitor
0.This is a delay circuit that delays the time that
the transistor
(Tr) will be switched OFF when
the output voltage of
IC, becomes low, so that
the glass is correctly opened to its full extent.
The motor operates for 0.7 second after the
glass reaches its lowermost position.

When, with the driver’s lap belt unfastened (the buckle switchis switched ON), the ignition switch is tunrned from the
“LOCK” or
“ACC” position to the “ON” position, the buzzer
will sound intermittently for approximately 6 seconds. If,however, the driver’s lap belt is fastened during that time, the
buzzer will be switched
OFF.
Note that the warning light when the ignition switch isactivated will also illuminate when the ignition switch is turned
from the “LOCK” or “ACC” position to the “ON” position.
Warning Alarm when the ignition Key is Left in the Ignition
The buzzer will sound continuously when all of these condi-
tions occur simultaneously: the key is in the key cylinder
(key-reminder switch A is switched ON), and the ignition
switch is at the “LOCK” or “ACC” position, and the driver’s
door is open (the door latch switch “open” is switched ON).
Warning Alarm when an Automatic Seat Belt Starts to
Move toward the “Release” Side
When the driver’s or front seat passenger’s automatic seat belt
starts to move toward the “release” side, the buzzer sounds
for approximately 0.7 second.AUTOMATlC SEAT BELT CONTROL UNIT INPUT/OUTPUT
