ELECTRICAL - Theft-alarm System8-33ARMING THE SYSTEM
After the following procedures have been completed, the SECURITY light illuminates for about 20 seconds,
and when illumination stops, the system is armed.
(1) Pull out the ignition key from the key cylinder.
(2) Open a door. (The other door is closed.)
(3) Lock the door with the key or the
keyless-locking method.
(The central door locking system will then function to lock all doors.)
NOTE(1) The system is set regardless of whether the hood and liftgate are open or
closed, and is armed as
soon as the light goes out.
(2) Even after the system has been armed, if the key is used to open the liftgate, the system will not be
activated; when the liftgate is then
closed, moreover, the system will be armed.
DISARMING THE SYSTEM
(1) The system will be disarmed if the key is used to unlock a door.
(2) If the system is armed while the driver is still in the vehicle, the system can be disarmed by inserting the
ignition key and turning it to the ACC or ON position.
(3) If the door lock is unlocked while closing the door or the door is ajar.
(4) If the door is unfastened while the SECURITY light illuminates.
ACTIVATING THE ALARM
(1) if an attempt is made to open a door, the liftgate or the hood, without using the key, while the system is
armed, the horn will sound intermittently and the headlights will flash on and off for approximately
three,
minutes.Furthermore, the starter circuit is interrupted at this time also, making starting of the engine impossible.
(2) if a further attempt at *forcible entry is made after the first three-minute alarm has finished, the
three-minute alarm will be activated again.
DEACTIVATING THE ALARM
(1) To deactivate the alarm, insert the key into the door’s key cylinder and turn the key.
(2) The alarm is deactivated and the system is disarmed when the iiftgate is unlocked with the key.
CHECKING THE SYSTEM OPERATION
The activation/operation of the system can be checked by following the steps below.
(1) Turn the ignition key to the ON position and then use the power-window switch to fully open the window
at the driver’s seat side.
(2) Turn the ignition key to the LOCK position and then remove the key from the ignition.
(3) Open only the driver’s door, and close all the other doors, as well as the hood and the rear hatch.
(4) Lock the driver’s door by the key or the
keyless-locking method.
(5) All doors will then be
locked, and the SECURITY light (within the combination meter) will illuminate; check
to be sure that illumination stops in about 20 seconds.
(6) After about two seconds have passed after the SECURITY light illumination stopped, reach through the
window of the driver’s door, pull up the lock lever to unlock the door, and then open the door.
(7) Check to be sure that, when the door is opened, the horn starts sounding and the headlights flash on and
Off.
(8) To stop the alarm, insert the key into the door’s key cylinder and turn the key.
!?iEeck the alarm for the opening of the liftgate or hood open the liftgate (or the hood) by using the
remote liftgate release lever (or the hood release lever),
located at the driver’s seat side either before the
alarm is activated by the opening of a door, or after the finish of the first three-minute alarm.

“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.
