System Description
INFOID:0000000001704084
DESCRIPTION
Operation Flow

Setting the vehicle security system
Initial condition• Ignition switch is in OFF position.
Disarmed phase• When the vehicle is being driven or when any door or trunk (sedan) is open, the vehicle security system is
set in the disarmed phase on the assumption that the owner is inside or near the vehicle.
Pre-armed phase and armed phase• The vehicle security system turns into the "pre-armed" phase (security lamp illuminates) when the BCM
receives LOCK signal from front door key cylinder switch, keyfob or Intelligent Key after all doors and trunk
(sedan) are closed.
• All doors and trunk (sedan) are closed after front doors are locked by key or door lock and unlock switch.
The security indicator lamp illuminates for 30 seconds. then, the system automatically shifts into the "armed"
phase.
Canceling the set vehicle security system
Armed phase is canceled when the driver unlocks the doors or the trunk (sedan) with the key, keyfob or Intelli-
gent Key.
Activating the alarm operation of the vehicle security system
Make sure the system is in the armed phase.
When one of the following operations is performed, the system sounds the horns and flashes the headlamps
for about 50 seconds.
1. Any door is opened before unlocking door with key, keyfob or Intelligent Key.
2. Door is unlocked without using key, keyfob or Intelligent Key.
3. Trunk (sedan) is opened without using the key, trunk lid opener switch, keyfob or Intelligent Key (sedan).
POWER SUPPLY AND GROUND
Power is supplied at all times• through 10A fuse [No.13, located in the fuse block (J/B)]

• to BCM terminal 38.
Ground is supplied• to BCM terminal 67
• through body grounds M57 and M61.
INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors and trunk (sedan).
To activate the vehicle security system, BCM must receive signals indicating the ignition switch is OFF, doors
and trunk (sedan) are closed and locked.
When a door or trunk (sedan) is open, BCM terminal 12, 13, 42, 43, 47 or 48 receives a ground signal from
each door or trunk switch. In addition to BCM, when back door is open, the Intelligent Key unit terminal 23
receives a ground signal from back door or trunk (sedan) through BCM terminal 30.
When front door LH is unlocked, BCM terminal 46 receives a signal from terminal 6 of main power window and
door lock/unlock switch.
When front door RH is unlocked, BCM terminal 46 receives a signal from terminal 2 of power window and door
lock/unlock switch RH.
VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by
• Opening a door without using the key, keyfob or Intelligent Key.
• Opening trunk without using the key, keyfob or Intelligent Key (sedan).
The vehicle security system will be triggered once the system is in armed phase,
• when BCM receives a ground signal at terminals 12, 13, 47, 48 (front or rear door switch), terminal 42
(sedan, trunk switch) or terminal 43 (hatchback, back door switch).
When the vehicle security system is triggered, ground is supplied intermittently
• from IPDM E/R terminal 45
• to horn relay terminal 1.
The headlamps flash and the horn sounds intermittently.
The alarm automatically turns off after 50 seconds, but will reactivate if the vehicle is tampered with again.
VEHICLE SECURITY SYSTEM DEACTIVATION
To deactivate the vehicle security system, a door or trunk (sedan) must be unlocked with the key, keyfob or
Intelligent Key.
When the key is used to unlock the driver door, BCM terminal 7 receives signal
• from terminal 3 of the front door key cylinder switch LH.
When the key is used to open the trunk (sedan), BCM terminal 41 receives signal
• from terminal 1 of the trunk key cylinder switch.
When the BCM receives an unlock signal from keyfob, Intelligent Key, front door key cylinder switch LH or
trunk key cylinder switch (sedan), the vehicle security system is deactivated (Disarmed phase).
PANIC ALARM OPERATION
Intelligent Key and remote keyless entry system may or may not operate vehicle security system (horn and
headlamps) as required.
When the remote keyless entry system is triggered, ground is supplied intermittently

DESCRIPTION
NOTE:
If customer reports a “No start” condition, request ALL KEYS to be brought to a Nissan dealer in case
of a NATS malfunction.
NATS (Nissan Anti-Theft System) has the following functions:
• NATS shows a higher anti-theft performance at preventing engine to be started by an unregistered key. (reg-
istered key: mechanical key and Intelligent Key).
• Only a key with key ID registered in BCM and ECM can start engine, it has a higher protection against auto
theft that duplicates keys.
• If a malfunction has been detected, security indicator will illuminate when ignition switch is in ON position.
• If the owner requires, mechanical key can be registered for up to 5 keys.
• During trouble diagnosis or when the following parts have been replaced, and if mechanical key is added,
registration* is required.
*: All mechanical keys of the vehicle should be registered.

• NATS trouble diagnoses, system initialization and additional registration of other NATS mechanical key IDs
must be carried out using CONSULT-III hardware and CONSULT-III NATS software. When NATS initializa-
tion has been completed, the ID of the inserted mechanical key can be displayed.
Regarding the procedures of NATS initialization and mechanical key ID registration, refer to CONSULT-III
operation manual NATS.
SECURITY INDICATOR
• Forewarns that the vehicle is equipped with NATS.
• Security indicator will not blink while the ignition knob is in ON or START state.
NOTE:
Because security indicator is highly efficient, the battery is barely affected.
Condition of Security Indicator
• When operating the ignition switch with Intelligent Key, security indicator lamp will turn off at once if ignition
switch is pressed and blinks when ignition switch is released.
• When operating the ignition switch with mechanical key security indicator will turn off at once if mechanical
key is inserted into key cylinder and blinks when mechanical key is removed.
(Once the mechanical key is inserted into key cylinder, BCM will only perform the key ID verification with
mechanical key)
System CompositionINFOID:0000000001704105
The function of the NATS consists of the following:
• Mechanical key
• NATS antenna amp. located in the ignition key cylinder
•BCM
• ECM (Engine control module)
• Security indicator
• Intelligent Key unit (if equipped)
NOTE:
The communication between ECM, BCM and/or Intelligent Key unit uses the CAN communication sys-
tem.
ECM Re-communicating FunctionINFOID:0000000001704106
Performing the following procedure can automatically perform re-communication of ECM and BCM or Intelli-
gent Key unit, but only when the ECM has been replaced with a new one which has never been energized on-
board.
(In this step, initialization procedure by CONSULT-III is not necessary)
NOTE:
•When registering new Key IDs or replacing the ECM other than brand new, refer to CONSULT-III
Operation Manual NATS.
