PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000007827577
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this
Service Manual.
WARNING:
Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision that would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see “SRS AIR BAG”.
• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the
battery, and wait at least 3 minutes before performing any service.
Precaution for Procedure without Cowl Top Cover
INFOID:0000000007579626

PRECAUTIONS FOR 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.) Therefore, ID verification cannot be per-
formed by mechanical key only.
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, 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 to start the ignition power supply.
6.
IPDM E/R turns the starter control relay ON for engine starting in advance.
7.
BCM detects that the selector lever position and brake pedal operating condition (CVT models), or clutch
pedal operation condition (M/T models).
8.
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.
9.
Power source is supplied to starter motor through the starter relay and the starter control relay.
CAUTION:
If a malfunction is detected in the Intelligent Key system, the “KEY” warning lamp in the combina-
tion meter illuminates. At that time, the engine cannot be started.
10. When BCM receives feedback signal from ECM indicating 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 automatically within 5 seconds.)
CAUTION:
When the Intelligent Key is carried 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 “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 integrated
into 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 can 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

NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS : System Description
INFOID:0000000007579652
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 cannot start the engine. When the Intelligent Key battery is
discharged, the NVIS (NATS) ID verification is performed between the transponder integrated into 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.
• The security indicator lamp on combination meter always blinks when the power supply position is any posi-
tion other than ON which warns that the NVIS (NATS) is on board the model.
• Up to 4 Intelligent Keys can be registered (including 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
• If ECM other than genuine part is installed, the engine cannot be started. For ECM replacement procedure,
refer to
.

< SYSTEM DESCRIPTION >
[WITH INTELLIGENT KEY SYSTEM]
SYSTEM
• The ID registration is a procedure that erases the current NVIS (NATS) ID once, and then registers a new ID.
Therefore before starting the registration operation, collect all registered Intelligent Keys from the customer.
• 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 power 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 position (CVT models), 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.
When push-button ignition switch is pressed, BCM turns ACC relay ON and transmits ignition power sup-
ply ON signal to IPDM E/R.
5.
IPDM E/R turns the starter control relay ON for engine starting in advance.
6.
IPDM E/R turns the ignition relay ON to start the ignition power supply.
7.
BCM detects that the selector lever position and brake pedal operating condition (CVT models), or clutch
pedal operation condition (M/T models).
8.
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.
9.
Power supply is supplied to the starter motor through the starter relay and the starter control relay.
10. When BCM receives feedback signal from ECM indicating that the engine is started, BCM transmits a
stop signal to IPDM E/R to stop cranking by turning off the starter motor relay. (If engine start is unsuc-
cessful, cranking stops automatically within 5 seconds.)
*: For the engine start condition, refer to “POWER SUPPLY POSITION CHANGE TABLE BY PUSH-BUTTON

VEHICLE SECURITY SYSTEM : System Description
INFOID:0000000007579654
• The vehicle security system has two alarm functions (theft warning alarm and panic alarm), and reduces the
possibility of a theft or mischief by activating horns and headlamps intermittently.
• The panic alarm does not start when the theft warning alarm is activating, and the panic alarm stops when
the theft warning alarm is activated.
The priority of the functions are as per the following.
THEFT WARNING ALARM
• The theft warning alarm function activates horns and headlamps intermittently when BCM detects that any
door is opened by unauthorized means, while the system is in the ARMED state.
• Security indicator lamp on combination meter always blinks when power supply position is any position other
than ON. Security indicator lamp blinking warns that the vehicle is equipped with a vehicle security system.

SYSTEM
• To lock/unlock all doors by operating remote controller button of Intelligent Key or door request switch, Intelligent Key must be within
the detection area of outside key antenna. For details, refer to
DLK-16, "DOOR LOCK FUNCTION : System Description"
.
• To open back door by operating back door opener switch, Intelligent Key must be within the detection area of outside key antenna. For
details, refer to
DLK-16, "DOOR LOCK FUNCTION : System Description"
DISARMED Phase
The vehicle security system is not set in the DISARMED 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, each phase switches to the DISARMED phase directly.
PRE-ARMED Phase
The PRE-ARMED phase is the transient state between the DISARMED phase and the ARMED phase. This
phase is maintained for 30 seconds, so that the owner can 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 switching 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 is opened without using
Intelligent Key, vehicle security system switches 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 accessed 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 the 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 between each phase and DISARMED phase.
The PRE-RESET phase is not available for this models.
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.
• 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
- PANIC ALARM button of Intelligent Key: Long pressed
- Any door request switch: ON
