Trouble Diagnoses
If no doors can not be unlocked by remote controller operation then the following procedure is required.
A) Unlock the vehicle by a mechanical key in the drivers door key cylinder.
Note: this may cause the alarm to sound.
B) Put the key in ignition, turn to ON position for at least five seconds. Assuming the ignition key contains
a valid transponder then a signal will be generated by the immobilizer which will disarm the alarm and
allow key learn mode to be entered.
C) Turn ignition OFF and wait for ten seconds.

THEFT WARNING SYSTEM
EL-311

SETTING THE THEFT WARNING SYSTEM
Initial condition
(1) Close all doors.
(2) Close hood and trunk lid.
Pre-armed phase and armed phase
The theft warning system turns into the“pre-armed”phase when hood, trunk lid and all doors are closed
and locked by key or multi-remote controller. (The security indicator lamp blinks intermittently for 30 sec-
onds.)
After about 30 seconds, the system automatically shifts into the“armed”phase (the system is set).
CANCELING THE SET THEFT WARNING SYSTEM
When the following (a) or (b) operation is performed, the armed phase is canceled.
(a) Unlock the doors with the multi-remote controller.
(b) Insert key in ignition key cylinder and turn it to ON. Then NATS IMMU will send a disarm signal to the
time control unit.
ACTIVATING THE ALARM OPERATION OF THE THEFT WARNING SYSTEM
Make sure the system is in the armed phase. When the following operation (a) (b) (c) (d) or (e)is performed,
the system sounds the horns and flashes the hazard lamp for about 30 seconds.
(a) Engine hood, trunk lid or any doors is opened before unlocking door with the multi-remote controller.
(b) A door is unlocked without using the multi-remote controller.
(c) The ignition is switched ON without using a NATS registered key.
(d) The ultra sonic sensing is triggered.
(e) A rear side or rear screen breakage is detected (Wagon).
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times.

Through 10A fuse [No.16 , located in the fuse block (J/B)]

to security indicator lamp terminal
2.
Power is supplied at all times

through 10A fuse [No.5 , located in the fuse block (J/B)]

to time control unit terminal
9.
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No.26 , located in the fuse block (J/B)]

to time control unit terminal
1.
Ground is supplied

to time control unit terminal
16.

through body groundsM6,M28andM26.
INITIAL CONDITION TO ARM THE SYSTEM
The operation of the theft warning system is controlled by all the doors, hood and trunk lid.
To activate the theft warning system, the time control unit must receive signals indicating all the doors, hood
and trunk lid are closed and the doors are locked.
When a door is open, time control unit terminal

6or
7receives a ground signal from each door switch.
When a door is unlocked, time control unit terminal

25,
35or
36receives a ground signal from terminal

5of each door unlock sensor.
When the hood is open, time control unit terminal

32receives a ground signal

from terminal
1of the hood switch

through body groundsE11andE37.
When the trunk lid is open, time control unit terminal

33receives a ground signal

from terminal
1of the trunk room lamp switch

through body groundsB18andB27.
When the back door, trunk or tail gate is open, time control unit terminal

33receives a ground signal

from terminal
1of the luggage room lamp switch

through body groundsB48andD110.
THEFT WARNING SYSTEM
System Description (Cont’d)
EL-313

THEFT WARNING SYSTEM ARMING (With key or remote controller used to lock doors)
If the key is used to lock doors, time control unit terminal
29receives a ground signal

from terminal
2of the key cylinder switch

through body groundsB18andB27.
If this signal or lock signal from remote controller is received by the time control unit, the theft warning sys-
tem will arm automatically.
When arming the theft warning system, time control unit terminal

18supplies ground intermittently to ter-
minal

1of the security indicator lamp. The security lamp will blink intermittently for approximately 30 sec-
onds (and then blink every 2.6 seconds, due to NATS).
Now the theft warning system is in armed phase.
THEFT WARNING SYSTEM ALARM OPERATION
The theft warning system is triggered by

opening a door

opening the trunk lid or back door

opening the hood

unlocking door without using the multi-remote controller

switching the ignition ON without a NATS registered key

triggering the ultra sonic sensors

smashing the back door or rear side quarter window (wagon model only).
Once the theft warning system is in armed phase, if the time control unit receives a signal at terminal

25,

35,
36(door unlock sensor),
6,
7(door switch),
33(trunk room lamp switch or luggage room lamp
switch),

32(hood switch),
31(smash sensor) or
17(ultra sonic sensor) the theft warning system will be
triggered. The hazard lamps flash and the horn sounds intermittently.
Power is supplied at all times

through 10A fuse [No.16 , located in the fuse block (J/B)].

to theft warning relay terminal
2.
If the theft warning system is triggered, ground is supplied

from terminal
43of the time control unit

to theft warning relay terminal
1.
The hazard lamps flash and the horn sounds intermittently.
The alarm automatically turns off after 30 seconds but will reactivate if the vehicle is tampered with again,
or if the initial cause remains present.
THEFT WARNING SYSTEM ALARM DISARMING
The theft warning system alarm operation can be deactivated by either unlocking the vehicle with the remote
controller, or turning the ignition to the“ON”position with a registered NATS key.
SMASH SENSOR
The smash sensor will trigger the alarm when the rear side or rear screen is broken. There are three wind-
shield protected:
1. Back door window. Sensor circuit is bonded to the glass.
2. Rear side quarter windows (one each side). Sensor circuit is bonded to the glass.
All three sensor are wired in series. By breaking any of the three windshields (sensor circuit open), the alarm
will sound.

Trouble Diagnoses
Alarm Trigger Feedback
To verify the last three triggers that activated the theft warning system, the Time Control Unit (TCU) can be
switched into Diagnostic Mode (see page EL-309 how to enter Diagnostic Mode).
Approximately 2 seconds after the TCU has finished flashing the hazard lamp to confirm that the Diagnos-
tic Mode has been successfully entered, the TCU will generate a short beep indicating the trigger that will
be displayed. A single beep means the most recent trigger, three beeps means the oldest trigger. Following
each beep or group of beeps, the hazard lamp will flash to indicate the alarm trigger.
Source of Alarm Trigger Number (of flashes)
Driver’s door lock status switch 1
Passenger door lock status switch 2
Rear door lock status switch 3
Ignition line 4
Driver’s door open switch 5
Other door open switch 6
Trunk or back door open switch 8
Hood switch 9
Ultra sonic sensors 10
Smash sensor (Wagon vehicles) 11
In case there have been no alarm triggers, there will be no indicator flashes between the audible signals.
After completing the alarm trigger feedback, the TCU will enter Diagnostic Mode as described on page
EL-309.
Before continuing trouble diagnoses on the next page, perform the checks as mentioned in the table on page
EL-310.
