INITIAL CONDITION TO ACTIVATE THE SYSTEMNBEL0120S02The operation of the theft warning system is controlled by the doors, hood and glass hatch.
To activate the theft warning system, the smart entrance control unit must receive signals indicating the doors,
hood and glass hatch are closed and the doors are locked.
When a door is open, smart entrance control unit terminal 28, 29 or 40 receives a ground signal from each
door switch.
When a door is unlocked, smart entrance control unit terminal 26, 36 or 37 receives a ground signal from ter-
minal 4 of each door unlock sensor or terminal 1 of back door unlock sensor.
When the hood is open, smart entrance control unit terminal 27 receives a ground signal
Ifrom terminal 1 of the hood switch
Ithrough body grounds E13 and E41.
When the glass hatch is open, smart entrance control unit terminal 38 receives a ground signal
Ifrom terminal 1 of the glass hatch switch
Ithrough body grounds D210, B11 and B22.
When the doors are locked with key or multi-remote controller and none of the described conditions exist, the
theft warning system will automatically shift to armed mode.
THEFT WARNING SYSTEM ACTIVATION (WITH KEY OR REMOTE CONTROLLER USED TO
LOCK DOORS)
NBEL0120S03If the key is used to lock doors, terminal 41 receives a ground signal
Ifrom terminal 3 of the key cylinder switch LH
Ithrough back grounds M77 and M111
Ifrom terminal 1 of the back door key cylinder switch
Ithrough body grounds B11, B22 and D210.
If this signal or lock signal from remote controller is received by the smart entrance control unit, the theft
warning system will activate automatically.
Once the theft warning system has been activated, smart entrance control unit terminal 31 supplies ground to
terminal 2 of the security indicator lamp.
The security lamp will illuminate for approximately 30 seconds and then blink.
Now the theft warning system is in armed phase.
THEFT WARNING SYSTEM ALARM OPERATIONNBEL0120S04The theft warning system is triggered by
Iopening a door
Iopening the hood or the glass hatch
Iunlocking door without using the key or multi-remote controller.
Once the theft warning system is in armed phase, if the smart entrance control unit receives a ground signal
at terminal 26, 36, 37 (door unlock sensor), 28, 29, 40 (door switch), 38 (glass hatch switch) or 27 (hood
switch), the theft warning system will be triggered. The headlamps flash and the horn sounds intermittently.
Power is supplied at all times
Ithrough 7.5A fuse (No. 52, located in fuse and fusible link box)
Ito horn relay terminals 1 and 3.
Ithrough 10A fuse (No. 54, located in fuse and fusible link box)
Ito horn relay terminal 6.
When the theft warning system is triggered, ground is supplied intermittently

THEFT WARNING SYSTEM DEACTIVATIONNBEL0120S05To deactivate the theft warning system, a door, the back door or the glass hatch must be unlocked with the
key or remote controller.
When the key is used to unlock the door, smart entrance control unit terminal 30 receives a ground signal
Ifrom terminal 1 of the LH key cylinder switch
Ifrom terminal 2 of the back door key cylinder switch.
When the key is used to open the glass hatch, smart entrance control unit terminal 42 receives a ground sig-
nal from terminal 3 of the back door key cylinder switch.
When the smart entrance control unit receives either one of these signals or unlock signal from remote
controller, the theft warning system is deactivated. (Disarmed phase)
PANIC ALARM OPERATIONNBEL0120S06Multi-remote control system may or may not operate theft warning system (horn and headlamps) as required.
When the multi-remote control system is triggered, ground is supplied intermittently.
Ifrom smart entrance control unit terminal 4
