Removal and Installation
IWhen removing or installing hood, place a cloth or other padding on hood. This prevents vehicle body from
being scratched.
IBumper fascia is made of plastic. Do not use excessive force and be sure to keep oil away from it.
IHood adjustment: Adjust at hinge portion.
IHood lock adjustment: After adjusting, check hood lock control operation. Apply a coat of grease to hood
locks engaging mechanism.
IHood opener: Do not attempt to bend cable forcibly. Doing so increases effort required to unlock hood.

SETTING THE THEFT WARNING SYSTEM
Initial condition
(1) Close all doors.
(2) Close hood.
Pre-armed phase and armed phase
The theft warning system turns into the ªpre-armedº phase when hood and all doors are closed and locked by
key or multi-remote controller. (The security indicator lamp blinks intermittently for 30 seconds.)
After about 30 seconds, the system automatically shifts into the ªarmedº 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) or (d) is performed, the
system sounds the horns and flashes the hazard lamp for about 30 seconds.
(a) Engine hood or any door 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 ultrasonic sensing is triggered.

INITIAL CONDITION TO ARM THE SYSTEM
The operation of the theft warning system is controlled by all the doors and hood.
To activate the theft warning system, the time control unit must receive signals indicating all the doors and
hood are closed and the doors are locked.
When a door is open, time control unit terminal
U06orU07receives a ground signal from each door switch.
When a door is unlocked, time control unit terminal
U25,U35orU36receives a ground signal from each door
unlock sensor.
When the hood is open, time control unit terminal
U32receives a ground signal

Ifrom terminalq
2of the key cylinder switch
Ithrough body grounds
B18andB10.
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
U18supplies ground intermittently to termi-
nalq
40of the combination meter. The security lamp will blink intermittently for approximately 30 seconds (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
Iopening a door
Iopening back door
Iopening the hood
Iunlocking door without using the multi-remote controller
Iswitching the ignition ON without a NATS registered key
Itriggering the ultrasonic sensors
Once the theft warning system is in armed phase, if the time control unit receives a signal at terminal
U25,
U35,U36(door unlock sensor),U06,U07(door switch),U32(hood switch), orU17(ultrasonic sensor) the theft
warning system will be triggered. 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 ªONº position with a registered NATS key.

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-182 how to enter Diagnostic Mode).
Approximately 2 seconds after the TCU has finished flashing the hazard lamp to confirm that the Diagnostic
Mode has been successfully entered, the TCU will generate a short beep indicating the trigger that will be dis-
played. 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
Ultrasonic sensors 10
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-182.
Before continuing trouble diagnoses on the next page, perform the checks as mentioned in the table on page
EL-183.
