PRECAUTIONS

PRECAUTION

PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"

INFOID:0000000007563201

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:0000000007563202

When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to
windshield.

Precaution for Battery Service

INFOID:0000000007563203

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.

Service Procedure Precautions for Models with a Pop-up Roll Bar

INFOID:0000000007563204

• Risk of passenger injury or death may increase if the pop-up roll bar does not deploy during a roll

over collision. In order to reduce the chance of an incident where the pop-up roll bar is inoperative,
all maintenance must be performed by a NISSAN or INFINITI dealer.

• Before removing and installing the pop-up roll bar component parts and harness, always turn the

ignition switch OFF, disconnect the battery negative terminal, and wait for 3 minutes or more. (The
purpose of this operation is to discharge electricity that is accumulated in the auxiliary power supply
circuit in the air bag diagnosis sensor unit.)

• When repairing, removing, and installing a pop-up roll bar, always refer to SRS AIR BAG and SRS

AIR BAG CONTROL warnings in the Service Manual.

• 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 performed by mechanical key only. In that case, the NVIS (NATS) ID verification can be performed
when Intelligent Key is inserted into key slot. If verification result is OK, engine can be started.

OPERATION WHEN INTELLIGENT KEY IS CARRIED

1.

When push-button ignition switch is pressed, BCM activates inside key antenna and transmits the request
signal to Intelligent Key.

2.

Intelligent Key receives the request signal and transmits the Intelligent Key ID signal to BCM.

3.

BCM receives the Intelligent Key ID signal via remote keyless entry receiver, and verifies it with the regis-
tered ID.

4.

If the verification result is OK, BCM turns ACC relay ON and transmits the ignition power supply ON signal
to IPDM E/R.

5.

IPDM E/R turns ignition relay ON and starts the ignition power supply.

6.

BCM detects that selector lever is in the P or N position.

7.

BCM transmits the starter request signal via CAN communication to IPDM E/R and turns starter relay in
IPDM E/R ON if BCM judges that the engine start condition* is satisfied.

8.

IPDM E/R turns starter control relay ON when receiving the starter request signal.

9.

Battery power is supplied through starter relay and starter control relay to operate starter motor.

CAUTION:

If a malfunction is detected in the Intelligent Key system, “KEY” warning lamp in the combination
meter illuminates. At that time, engine cannot be started.

10. When BCM received feedback signal from ECM indicating that the engine is started, BCM transmits a

stop signal to IPDM E/R and stops the cranking by turning OFF starter motor relay. (If the engine start is
unsuccessful, the cranking operation stops automatically within 5 seconds.)

CAUTION:

When Intelligent Key is carried outside of the vehicle (inside key antenna detection area) while
ignition switch is in the ACC or ON position, even if the engine start condition* is satisfied, engine
cannot be started.

*: For the engine start condition, refer to “IGNITION SWITCH POSITION CHANGE TABLE BY PUSH-BUT-
TON IGNITION SWITCH OPERATION”.

OPERATION RANGE

Engine can be started when Intelligent Key is inside the vehicle. However, sometimes engine might not start
when Intelligent Key is on instrument panel or in glove box.

OPERATION WHEN KEY SLOT IS USED

When the Intelligent Key battery is discharged, the NVIS (NATS) ID verification between BCM and transpon-
der (integrated into Intelligent Key) is performed when Intelligent Key is inserted into key slot.
For details relating to starting the engine using key slot, refer to

SEC-13, "NISSAN VEHICLE IMMOBILIZER

SYSTEM-NATS : System Description"

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

NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS : System Description

INFOID:0000000007563230

SYSTEM DESCRIPTION

• The NIssan Vehicle Immobilizer System-NATS [NVIS (NATS)] prevents engine being started by Intelligent

Key whose ID is not registered to the vehicle (BCM). It has a higher protection against auto theft involving
the duplication of mechanical keys.

• The mechanical key integrated in the Intelligent Key cannot start the engine. When Intelligent Key battery is

discharged, the NVIS (NATS) ID verification is performed between BCM and transponder integrated into
Intelligent Key when Intelligent Key is inserted into 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 ignition switch is in any position except ON, to warn that the

vehicle is equipped with NVIS (NATS).

• Up to 4 Intelligent Key can be registered (Including the standard ignition key) on request from the owner.
• When replacing ECM, BCM or Intelligent Key, the specified procedure (Initialization and registration) using

CONSULT is required.

• Possible symptom of NVIS (NATS) malfunction is “Engine can not start”. However, this symptom may occur

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

EC-116, "Work Procedure"

.

SYSTEM

• The ID registration is a procedure that erases the current NVIS (NATS) ID, and then registers a new ID.

Therefore, before starting the registration operation, collect all registered Intelligent Keys from the customer.

• When registering Intelligent Key, perform only one procedure to register both IDs [Intelligent Key ID and

NVIS (NATS) ID] simultaneously.

SECURITY INDICATOR LAMP

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

OPERATION WHEN INTELLIGENT KEY IS INSERTED INTO KEY SLOT

1.

When Intelligent Key is inserted into key slot, BCM activates NATS antenna amp. that is integrated into
key slot to transmit the request signal to Intelligent Key.

2.

Intelligent Key receives the request signal and transmits the Intelligent Key ID signal to BCM.

3.

BCM receives the Intelligent Key ID signal via NATS antenna amp. and verifies it with the registered ID.

4.

If the verification result is OK, BCM turns ACC relay ON and transmits the ignition power supply ON signal
to IPDM E/R.

5.

IPDM E/R turns ignition relay ON and starts the ignition power supply.

6.

BCM detects that selector lever is in the P or N position.

7.

BCM transmits the starter request signal via CAN communication to IPDM E/R and turns starter relay in
IPDM E/R ON if BCM judges that the engine start condition* is satisfied.

8.

IPDM E/R turns starter control relay ON when receiving the starter request signal.

9.

Battery power is supplied through starter relay and starter control relay to operate starter motor.
