rMULTI-PURPOSE FUSES
The multi-purpose fuses are located within the junction block at
the lower part of the instrument panel (at the driver’s seat side).
These fuses are all the blade type; 1 O-ampere, 15-ampere and
30-ampere fuses are used.

IDELAYED SWITCH-OFF DOME LIGHT
When the door is closed with the dome light switch in
thtDOOR position and ignition switch in the OFF position, the
dome light stays lit for a given period of time and then dims
before going out.
If the ignition switch’ is in the ON position, the dome light does
not dim but goes out as soon as the door is closed.
The foot light and ignition key illumination light operate in
exactly the same way.

1.When a door is opened (the door switch placed
in the ON state) with the dome light switch in
the DOOR position, current flows from the
battery to the dome light to the dome light
switch (and the ‘foot light and ignition key
illumination light) to diode
DI to the door switch
to the ground, and the dome light lights.
2.When the ignition switch is in the OFF position,
L signal is input to the NOT circuit and inverted Hsignal input to the AND circuit. When the door is
-closed at this time (door switch OFF), the circuit
. .----es :- _.a -&Aso the AND circuit outputs
H signal to operate
the timer circuit.
The timer circuit outputs to the base of
Tr the
signal which gradually varies in about six
seconds. So the voltage applied to the light
-gradually reduced to cause the light to dim.
3.When the ignition switch is in the ON position,His input to the NOT circuit
ahd inverted L signal
input to the AND circuit. So when the door is
closed, the timer circuit does not operate, and
the light does not dim but goes out immediately.

Init !,WF%;$TlON OF THE CENTRAL DOOR

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
Tr? for
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,
Trp, and to ground,
thus switching ON the “unlock” side contacts of the
door lock relay and activating the door lock
actuators, thereby the doors.

The motor operates to move the slide anchor.t receives direction of rotation, start, and stop signals from the
:ontroi unit. and operates according to these signals.Jote that an automatic seat belt motor relay is installed at the motor.f. due to a malfunction, the slide anchor stops before it reaches the2nd of its travel, note that the slide anchor can also be movednanually by using the hexagonal wrench included with the vehicle.
-ocated at the door latch.
rhese switches detect the open/close condition of the doors.
The following components also constitute the automatic seat belts system.

Kev-reminder Switch

Buzzer
rhis switch sends a High signal to the control unit when the ignition ‘ncorporated within the key cylinder.
“ON” signals are sent to the control unit by switch A while the key is
inserted in the key cylinder; “ON” signals are sent by switch
Bwhen the key is not in the key cylinder.
Located at the rear side of the instrument panel.The power for this buzzer is supplied from the battery through fuse
No. 1.
Note that the buzzer sounds an alarm to warn that the key has beenleft in the ignition.

lsPo2eeWarning Alarm when the Driver’s Lap Belt is not Fastened
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
