System Description

INFOID:0000000009722701

SYSTEM DESCRIPTION

• The NVIS (NATS) is an anti-theft system by registering an Intelligent Key ID into 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.

• Security indicator lamp always blinks when the power supply position is in any position except ON, to warn

that the NVIS (NATS) is on board the model.

• Intelligent Key can be registered up to 4 keys (Including the standard ignition key) on request from the

owner.

• When replacing ECM, BCM or Intelligent Key, the specified procedure (Initializing and registration) using

CONSULT is required.

• When NVIS (NATS) has a malfunction, Engine may not start. However, the engine can not be started

because of other than NATS malfunction. So, start the trouble diagnosis according 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 RECOMMUNICATING FUNCTION : Special Repair Requirement"

.

PRECAUTIONS FOR KEY REGISTRATION

• The key registration is a procedure that erases the current NATS ID once, and then re-registers a new ID.

Therefore the registered Intelligent Key is necessary for this procedure. Before starting the registration oper-
ation 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 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
the operation when carrying the key. The registrations of both systems should be performed.

SECURITY INDICATOR LAMP

• Warns that the vehicle is equipped with NVIS (NATS).
• The security indicator lamp always blinks when the ignition switch is in any position except ON.
NOTE:
Because security indicator lamp is highly efficient, the battery is barely affected.

POWER SUPPLY POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH OPERA-
TION

The power supply position changing operation can be performed with the following operations.
NOTE:
• When an Intelligent Key is within the detection area of inside key antenna and when it is inserted to the key

slot, it is equivalent to the operations below.

• When starting the engine, the BCM monitors under the engine start conditions,
- Brake pedal operating condition
- Selector lever position
- Vehicle speed
• This models do not have the steering lock system. However, power supply position changes to the LOCK

position without steering lock operation when the following conditions are fulfilled. 

- Ignition switch: OFF
- Shift lever position: P
- Any of the following condition is met
• Opening door
• Closing door
• Door is locked by request switch operation
• Door is locked by Intelligent Key operation
