Is malfunctioning part detected?
YES >> GO TO 8.
NO >> Check voltage of related BCM terminals using CONSULT-III.
8.REPAIR OR REPLACE THE MALFUNCTIONING PART
1. Repair or replace the malfunctioning part.
2. Reconnect parts or connectors disconnected during Diagnostic Procedure again after repair and replace-
ment.
3. Check DTC. If DTC is detected, erase it.
>> GO TO 9.
9.FINAL CHECK
When DTC is detected in step 2, perform DTC Confirmation Procedure or Component Function Check again,
and then check that the malfunction has been repaired securely.
When symptom was described from the customer, refer to confirmed symptom in step 3 or 4, and check that

System DiagramINFOID:0000000003814906
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).

OPERATION FLOW
SETTING THE VEHICLE SECURITY SYSTEM
Initial Condition
 Ignition switch is in the OFF position.
Disarmed Phase
 When any door, trunk lid or hood is open, the vehicle security system is set in the disarmed phase on the
assumption that the owner is inside or near the vehicle.
 When the vehicle security system is in the disarmed phase, the security indicator lamp blinks every 2.4 sec-
onds.
Pre-armed Phase and Armed Phase
When the following operation is performed, the vehicle security system turns into the “pre-armed” phase. (The
security indicator lamp illuminates.)
1. BCM receives LOCK signal from front door request switch or Intelligent Key, after trunk lid, hood and all
doors are closed.
2. The security indicator lamp illuminates for 30 seconds. Then, the system automatically shifts into the
“armed” phase.
