(1) A crash bead is provided in the inner cowl top panel that
absorbs energy during collision. It prevents the steering
wheel from protruding into the driver during collision,
thereby ensuring safety of the driver.
(2) The safety hook prevents the hood from entering the
passenger compartment during collision, thereby ensuring
safety of the driver as well as passengers.
DASH PANEL
The dash panel consists of the deadening sheet sandwiched
between two sheets of panel. Coupled with the silencer
attached to the panel on the passenger
companment side, the
dash panel is effective in deadening noise and resisting to
vibration.SIDE BODY

Ri... 4sThe central door-lock system, by which all doors can
be locked or unlocked (from the inside by using the
inside door lock knob at either front door, or from
the outside by using the door key), not only sewes
to reduce the trouble of individually locking orunlocking each door when passengers get out or
get in, but also maintains passenger safety.
For the central door-lock system, the operation of
the lock actuator is regulated by the door control
unit.

The door lock actuator incorporates an internal PTC thermist’-so as to Prevent damage as the result of overheating of

is an acronym for Positive Temperature Coefficient.
The thermistor with a positive temperature coefficient

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.

---IBatteryOPERATION OF THE POWER WINDOWS

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.
