THEFT WARNING SYSTEM ARMING (With key or remote controller used to lock doors)
If the key is used to lock doors, time control unit terminal29receives a ground signal
from terminal2of 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) or17(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 terminal2.
If the theft warning system is triggered, ground is supplied
from terminal43of the time control unit
to theft warning relay terminal1.
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.
