System DescriptionINFOID:0000000003814903
The engine start function of Intelligent Key system is a system that makes it possible to start and stop the
engine without removing the key. It verifies the electronic ID using two-way communication when pressing
the push-button ignition switch while carrying the Intelligent Key, which operates based on the results of
electronic ID verification for Intelligent Key using two-way communication between the Intelligent Key and
the vehicle.
NOTE:
The driver should carry the Intelligent Key at all times.
Intelligent Key has 2 IDs [for Intelligent Key and for NVIS (NATS)]. It can perform the door lock/unlock oper-
ation and the push-button ignition switch operation when the registered Intelligent Key is carried.
When the Intelligent Key battery is discharged, it can be used as emergency back-up by inserting the Intelli-
gent Key to the key slot. At that time, perform the NVIS (NATS) ID verification. If it is used when the Intelli-
gent Key is carried, perform the Intelligent Key ID verification.
If the ID is successfully verified, and when push-button ignition switch is pressed, steering lock will be
released and starting the engine will be possible.
If the door lock/unlock operation is performed when the Intelligent Key battery is discharged, all doors lock/
unlock can be performed by operating the driver door key cylinder using the mechanical key set in the Intel-
ligent Key.
Up to 4 Intelligent Keys can be registered (Including the standard Intelligent Key) on request from the owner.
NOTE:
Refer to SEC-9, "
System Description" for any functions other than engine start function of Intelligent Key
system.
PRECAUTIONS FOR INTELLIGENT KEY SYSTEM
In the Intelligent Key system, the transponder [the chip for NVIS (NATS) ID verification] is integrated
into the Intelligent Key. (For the conventional models, it is integrated into the mechanical key.) There-
fore, the mechanical key cannot perform the ID verification, and thus it cannot start the engine.
Instead, the NVIS (NATS) ID verification can be performed by inserting the Intelligent Key into the key
slot, and then it can start the engine.
OPERATION WHEN INTELLIGENT KEY IS CARRIED
1. When the push-button ignition switch is pressed, the BCM signals the inside key antenna and transmits
the request signal to the Intelligent Key.
2. The Intelligent Key receives the request signal and transmits the Intelligent Key ID signal to the BCM via
the remote keyless entry receiver.
3. The BCM receives the Intelligent Key ID signal and verifies it with the registered ID.

System DescriptionINFOID:0000000003814907
The NVIS (NATS) is an anti-theft system by registering an Intelligent Key ID in to the vehicle and prevents
the engine being started by an unregistered Intelligent Key. It has a higher protection against auto thefts that
duplicate mechanical key.
It performs the ID verification when starting the engine in the same way as the Intelligent Key system. But, it
performs the NVIS (NATS) ID verification when inserting the Intelligent Key and performs the Intelligent Key
ID verification when carrying the Intelligent Key.
The mechanical key integrated in the Intelligent Key cannot start the engine. When the Intelligent Key bat-
tery is discharged, the NVIS (NATS) ID verification memorized to the transponder integrated with Intelligent
Key is performed by inserting the Intelligent Key into the key slot. If the verification results are OK, the
engine start operation can be performed by the push-button ignition switch operation.
Locate the security indicator and apply the anti-theft system equipment sticker, forewarn that the NVIS
(NATS) is onboard with the model.
The security indicator always blinks when the power supply position is in LOCK, OFF and ACC position.
Up to 4 Intelligent Keys can be registered (Including the standard ignition key) on request from the owner.
The specified registration is required when replacing ECM, BCM or Intelligent Key. The registrations proce-
dure for NVIS (NATS) and registration procedure for Intelligent Key when installing the BCM, refer to CON-
SULT-III Operation Manual NATS-IVIS/NVIS.
Possible symptom of NVIS (NATS) malfunction is “Engine can not start”. The engine can be started with the
Intelligent Key system and NVIS (NATS). Identify the possible causes according to “Work Flow”. Refer to
SEC-5, "
Work Flow".
If ECM other than Genuine NISSAN is installed, the engine cannot be started. For ECM replacement proce-
dure, refer to SEC-8, "
ECM RE-COMMUNICATING FUNCTION : Special Repair Requirement".
PRECAUTIONS FOR KEY REGISTRATION
The key registration is a procedure that erases the current NVIS (NATS) ID once, and then re-registers a
new ID operation. Therefore the registered Intelligent Key is necessary for this procedure. Before starting
the registration operation collect all registered Intelligent Keys from the customer.
When registering the Intelligent Key, performs only one procedure to register simultaneously both IDs (NVIS
“NATS” ID registration and Intelligent Key ID registration).
The NVIS (NATS) ID registration is the procedure that registers the IDs stored into the transponder (inte-
grated in Intelligent Key) to BCM.
The Intelligent Key ID registration is the procedure that registers the ID to BCM.
When performing the Intelligent Key system registration only, the engine cannot be started by inserting the
key into the key slot. When performing the NVIS (NATS) registration only, the engine cannot be started by
pressing the push-button ignition switch when carrying the Intelligent Key. The registrations of both systems
should be performed.
SECURITY INDICATOR LAMP
Warns that the vehicle is equipped with NVIS (NATS).
