INTELLIGENT KEY SYSTEM
Revision: June 20062007 Versa
System DescriptionEIS0091W

The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock/
unlock function), and start the engine (engine start function) by carrying around the Intelligent Key (without
some key operation), which operates based on the results of electronic ID verification using two-way com-
munications between the Intelligent Key and the vehicle (Intelligent Key unit).

Vehicles equipped with a manual transmission include a key interlock solenoid located in the steering col-
umn to prevent accidental shut-off of the ignition switch and locking of the steering wheel during driving
condition when the vehicle is moving.
CAUTION:
The driver should always carry the Intelligent Key

Operation of the remote controller buttons on the Intelligent Key also provides the same functions as the
remote control entry system. (Remote keyless entry functions)

If an action that does not meet the operating conditions of the Intelligent Key system is taken, the buzzer
goes off to inform the driver. (Warning chime functions)

When a door lock is locked or unlocked with request switch or remote controller button operation, the haz-
ard lamps flash and the buzzer (outside vehicle) sounds (Hazard and buzzer reminder function).

Even if the Intelligent Key battery is completely discharged, the door locks can be locked and unlocked
and the engine started with the mechanical key built into the Intelligent Key.

The settings for each function can be changed with the CONSULT-II.

If an Intelligent Key is lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can
be registered.

It has been made possible to diagnose the system and register an Intelligent Key with the CONSULT-II.

Revision: June 20062007 Versa
System DescriptionEIS0093O
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.
(registered 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.
–ECM
–BCM
–Mechanical key

NATS trouble diagnoses, system initialization and additional registration of other NATS mechanical key
IDs must be carried out using CONSULT-II hardware and CONSULT-II NATS software. When NATS ini-
tialization 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-II
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 igni-
tion 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 mechani-
cal 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 CompositionEIS0093P
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)

NATS (NISSAN ANTI-THEFT SYSTEM)
Revision: June 20062007 Versa
NOTE:
The communication between ECM, BCM and/or Intelligent Key unit uses the CAN communication sys-
tem.
ECM Re-communicating FunctionEIS0093Q
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-II is not necessary)
NOTE:

When registering new Key IDs or replacing the ECM other than brand new, refer to CONSULT-II
Operation Manual NATS.

If multiple keys are attached to the key holder, separate them before work.

Distinguish keys with unregistered key ID from those with registered ID.
1. Install ECM.
2. Use a registered key (*), turn ignition switch to “ON”.
*: To perform this step, use the key that has been used before to perform ECM replacement.
3. Maintain ignition switch in “ON” position for at least 5 seconds.
4. Turn ignition switch to “OFF”.
5. Start engine.
If engine can be started, procedure is completed.
If engine cannot be started, refer to CONSULT-II Operation Manual NATS and initialize control unit.
