INPUT/OUTPUT SIGNAL CHART

SYSTEM DESCRIPTION

• The NVIS (NATS) is an anti-theft system by registering an Intelligent Key ID in to the vehicle and prevents

the hybrid system 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 hybrid system 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 Intelli-

gent Key ID verification when carrying the Intelligent Key.

• The Intelligent Key system of L32 is not the same as the conventional models. The mechanical key inte-

grated in the Intelligent Key cannot start the hybrid system. When the Intelligent Key battery 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 hybrid system start

operation can be performed by the push-button ignition switch operation.

• The security indicator always blinks when the Intelligent Key is removed from the key slot and when the

push-button ignition switch is in LOCK position.

• Intelligent Key can be registered with up to 4 keys on request from the owner.

• The specified registration is required when replacing ECM, BCM or Intelligent Key. The registration 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 “hybrid system cannot start”. In L32, the hybrid system can

be started with the Intelligent Key system and NVIS (NATS). Identify the possible causes according to “Work

Flow”, Refer to

SEC-4, "Work Flow"

• If ECM other than Genuine NISSAN part is installed, the hybrid system cannot be started. For ECM replace-

ment procedure, refer to

SEC-9, "ECM RE-COMMUNICATING FUNCTION : Special Repair Requirement"

[INTELLIGENT KEY SYSTEM]

NVIS (NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS)

• 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 ID (NVIS

“NATS” ID registration and Intelligent Key ID registration).

The NVIS (NATS) ID registration is the procedure that registers the ID 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 hybrid system cannot be started by insert-

ing the key into the key slot. When performing the NVIS (NATS) registration only, the hybrid system cannot

be started by the operation when carrying the key. The registration of both systems should be performed.

SECURITY INDICATOR

• Warns that the vehicle is equipped with NVIS (NATS).

• The security indicator always blinks when the Intelligent Key is removed from the key slot and when the igni-

tion switch is in LOCK position.

NOTE:

Because security indicator is highly efficient, the battery is barely affected.
