SYSTEM DESCRIPTION
• The engine start function of Intelligent Key system makes it possible to start and stop the engine without
using the key, based on the electronic ID verification. The electronic ID verification is performed between
BCM and Intelligent Key when the push-button ignition switch is pressed while the Intelligent Key is within
the detection area of inside key antenna.
NOTE:
The driver should carry the Intelligent Key at all times.
• Intelligent Key has 2 IDs [Intelligent Key ID and NVIS (NATS) ID]. It can perform the door lock/unlock opera-
tion and the push-button ignition switch operation when the registered Intelligent Key is carried.
• When Intelligent Key battery is discharged, engine c an be started by operating push-button ignition switch
after contacting Intelligent Key backside to push-button i gnition switch. At that time, the NVIS (NATS) ID ver-
ification is performed.
• If the ID is successfully verified, when push-button ignition switch is pressed, the engine can be started.
• Up to 4 Intelligent Keys can be registered (Includi ng the standard Intelligent Key) upon request from the cus-
tomer.

NOTE:
Refer to DLK-23, "INTELLIGENT KEY SYSTEM : System Description"
for any functions other than engine
start function of Intelligent Key system.
PRECAUTIONS FOR INTELLIGENT KEY SYSTEM
The transponder [the chip for NVIS (NATS) ID verifi cation] is integrated into the Intelligent Key.
In that case, the NVIS (NATS) ID verification can be performed when Intelligent Key backside is con-
tacted to push-button ignition switch. If verification result is OK, engine can be started.
OPERATION WHEN INTELLIGENT KEY IS CARRIED
1. When the push-button ignition switch is pressed, the BCM activates 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.
3. BCM receives the Intelligent Key ID signal via remote keyless entry receiver and verifies it with the regis-
tered ID.
4. BCM turns ACC relay ON and transmits the ignition power supply ON signal to IPDM E/R.
5. IPDM E/R turns the ignition relay ON and starts the ignition power supply.
6. BCM detects that the selector leve r position and brake pedal operating condition.
7. BCM transmits the starter request signal to IPDM E/R and turns the starter relay in IPDM E/R ON if BCM judges that the engine start condition* is satisfied.
8. IPDM E/R turns the starter control relay ON when receiving the starter request signal.
9. Power supply is supplied through the starter relay and the starter control relay to operate the starter motor. CAUTION:
If a malfunction is detected in the Intelligent Key system, the “KEY” warning lamp in the combina-
tion meter illuminates. At that ti me, the engine cannot be started.
10. When BCM receives feedback signal from ECM indicati ng that the engine is started, the BCM transmits a
stop signal to IPDM E/R and stops cranking by turning OFF the starter motor relay. (If engine start is
unsuccessful, cranking stops autom atically within 5 seconds.)
CAUTION:
When the Intelligent Key is carri ed outside of the vehicle (inside key antenna detection area) while
the power supply is in the ACC or ON position, even if the engine start condition* is satisfied, the
engine cannot be started.
*: For the engine start condition, refer to the tabl e below “POWER SUPPLY POSITION CHANGE TABLE BY
PUSH-BUTTON IGNITION SWITCH OPERATION”.
OPERATION RANGE
Engine can be started when Intelligent Key is inside the vehicle. However, sometimes engine may not start
when Intelligent Key is on instrument panel or in glove box.
ENGINE START OPERATION WHEN INTELLIGENT KEY IS CONTACTED TO PUSH-BUTTON IG-
NITION SWITCH
When Intelligent Key battery is discharged, the NVIS (NATS) ID verification between transponder in Intelligent
Key and BCM is performed when Intelligent Key backside is contacted to push-button ignition switch. If the
verification result is OK, engine can be started.
POWER SUPPLY POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH OPERA-
TION
The power supply position changing operation c an be performed with the following operations.
NOTE:
• When an Intelligent Key is within the detection area of inside key antenna and when Intelligent Key backside
is contacted to push-button ignition switch, 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

NISSAN VEHICLE IMMOBILIZER SYST EM-NATS : System DescriptionINFOID:0000000009461089
SYSTEM DESCRIPTION
• The NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS [NVIS (NATS)] prevents the engine from being
started by Intelligent Key whose ID is not registered to the vehicle (BCM). It has higher protection against
auto theft involving the duplication of mechanical keys.
• The ignition key integrated in the Intelligent Key c annot start the engine. When the Intelligent Key battery is
discharged, the NVIS (NATS) ID verification is per formed between the transponder integrated with Intelligent
Key and BCM via NATS antenna amp. when the Intelligent Key backside is contacted to push-button ignition
switch. If the verification results are OK, the engine start operation can be performed by the push-button igni-
tion switch operation.
• Locate the security indicator lamp and apply the anti-t heft system equipment sticker that warns that the NVIS
(NATS) is on-board the model.
• Security indicator lamp always blinks when the pow er supply position is any position other than ON.
• Up to 4 Intelligent Keys can be registered (includi ng the standard ignition key) upon request from the owner.
• Specified registration is required when replacing ECM, BCM or Intelligent Key.
• Possible symptom of NVIS (NATS) malfunction is “Engine cannot start”. The engine can not be started
because of other than NVIS (NATS) malfunction, so start the trouble diagnosis according to SEC-63, "Work
Flow".
• If ECM other than genuine part is installed, the engi ne cannot be started. For ECM replacement procedure,
refer to EC-540, "Removal and Installation"
(with QR25DE) EC-997, "Removal and Installation" (with
VQ35DE).

PRECAUTIONS FOR KEY REGISTRATION
• The ID registration is a procedure that erases the cu rrent NVIS (NATS) ID once, and then reregisters a new
ID. Therefore before starting the registration operation, collect all registered Intelligent Keys from the cus-
tomer.
• When registering the Intelligent Key, perform only one procedure to simultaneously register both ID [NVIS
(NATS) ID and Intelligent Key ID].
SECURITY INDICATOR LAMP
• Warns that the vehicle is equipped with NVIS (NATS).
• Security indicator lamp always blinks when the pow er supply position is any position other than ON.
NOTE:
Because security indicator lamp is highly efficient, the battery is barely affected.
ENGINE START OPERATION WHEN INTELLIGENT KEY IS CONTACTED TO PUSH-BUTTON IG-
NITION SWITCH
1. When brake pedal is depressed while selector lever is in the P (Park) position, BCM activates NATS
antenna amp. that is located behind push-button ignition switch.
2. When Intelligent Key (transponder built-in) backside is contacted to push-button ignition switch, BCM
starts NVIS (NATS) ID verification between BCM and Intelligent Key (transponder built-in) via NATS
antenna amp.
3. When the NVIS (NATS) ID verification result is OK, buzzer in combination meter sounds and BCM trans-
mits the result to ECM.
4. BCM turns ACC relay ON and transmits ignition power supply ON signal to IPDM E/R.
5. IPDM E/R turns the ignition relay ON and starts the ignition power supply.
6. BCM detects that the selector lever position is P (Park) or N (Neutral).
7. BCM transmits starter request signal to IPDM E/R and turns the starter relay in IPDM E/R ON if BCM
judges that the engine start condition* is satisfied.
8. IPDM E/R turns the starter control relay ON when receiving the starter request signal.
9. Power supply is supplied through the starter relay and the starter control relay to operate the starter motor.
10. When BCM receives feedback signal from ECM indicating that the engine is started, BCM transmits a stop signal to IPDM E/R and stops cranking by turning of f the starter motor relay. (If engine start is unsuc-
cessful, cranking stops automatically within 5 seconds.)
*: For the engine start condition, refer to the table “POWER SUPPLY POSITION CHANGE TABLE BY PUSH-
BUTTON IGNITION SWITCH OPERATION” below.

DISARMED Phase
The vehicle security system is not set in the DISAR MED phase. The vehicle security system stays in this
phase while any door is open because it is assumed that the owner is inside or nearby the vehicle. Security
indicator lamp blinks every 2.4 seconds.
When the vehicle security system is reset, eac h phase switches to the DISARMED phase directly.
PRE-ARMED Phase
The PRE-ARMED phase is the transient state bet ween the DISARMED phase and the ARMED phase. This
phase is maintained for 30 seconds so that the owner c an reset the setting due to a mis-operation. This phase
switches to the ARMED phase when vehicle conditions are not changed for 30 seconds. Security indicator
lamp illuminates while being in this phase.
To reset the PRE-ARMED phase, refer to the s witching condition of No. 10 in the table above.
ARMED Phase
The vehicle security system is set and BCM monitors all necessary inputs. If any door or hood is opened with-
out using Intelligent Key, vehicle security system switc hes to the ALARM phase. Security indicator lamp blinks
every 2.4 seconds.
To reset the ARMED phase, refer to the switching condition of No. 11 in the table above.
ALARM Phase
BCM transmits “Theft Warning Horn Request” signal and “High Beam Request” signal intermittently to IPDM
E/R via CAN communication. In this phase, horns and headlamps are activated intermittently for approxi-
mately 50 seconds to warn that the vehicle is a ccessed by unauthorized means. ON/OFF timing of horns and
headlamps are synchronized. After 50 seconds, the vehicle security system returns to the ARMED phase. At
this time, if BCM still detects unauthorized access to t he vehicle, the system is switched to the ALARM phase
again. This RE-ALARM operation is carried out a maximum of 2 times.
To cancel the ALARM operation, refer to the switching condition of No. 12 in the table above.
NOTE:
If a battery terminal is disconnected during the ALARM phase, theft warning alarm stops. But when the battery
terminal is reconnected, theft warning alarm is activated again.

PRE-RESET Phase
The PRE-RESET phase is the transient state betw
een each phase and DISARMED phase. If only the condi-
tion of hood is not satisfied, the system switches to the PRE-RESET phase. Then, when any condition is
changed, the system switches to the DISARMED phase or PRE-ARMED phase.
PANIC ALARM
• The panic alarm function activates horns and headlamps intermittently when the owner presses the PANIC
ALARM button of Intelligent Key outside the vehicle while the power supply position is OFF or LOCK.
• When BCM receives panic alarm signal from Intelligent Key, BCM transmits “Theft Warning Horn Request”
signal and “High Beam Request” signal intermittently to IPDM E/R via CAN communication. To prevent the
activation due to mis-operation of Intelligent Key by owner, the panic alarm function is activated when BCM
receives the signal for 0.4 - 0.6 seconds.
• Panic alarm operation is maintained for 25 seconds.
• Panic alarm operation is cancelled when BCM receives one of the following signals:
- LOCK button of Intelligent Key: ON
- UNLOCK button of Intelligent Key: ON
