PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000012430439
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 severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 three mi nutes before performing any service.
Precaution for WorkINFOID:0000000012430440
• When removing or disassembling each component, be ca reful not to damage or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.
• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component with a shop cloth or vinyl tape to protect it.
• Protect the removed parts with a shop cloth and prevent them from being dropped.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusabl e part, always replace it with a new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After installation is complete, be sure to check that each part works properly.
• Follow the steps below to clean components:
- Water soluble dirt:
• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.
• Then rub with a soft, dry cloth.
-Oily dirt:
• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty
area.
• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.
• Then rub with a soft, dry cloth.
- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.
- For genuine leather seats, use a genuine leather seat cleaner.

Component Function
1. Combination meter Combination meter transmits the vehicle
speed signal to BCM via CAN communica-
tion.
BCM also receives the vehicle speed signal
from ABS actuator and electric unit (control
unit) via CAN communication. BCM com-
pares both signals to detect the vehicle
speed.
Security indicator lamp is located on combi-
nation meter.
Security indicator lamp blinks when ignition
switch is in any position other than ON to
warn that NISSAN VEHICLE IMMOBILIZER
SYSTEM-NATS [NVIS (NATS)] is on board.
Refer to MWI-8, "
METER SYSTEM : Compo-
nent Parts Location".
2. ABS actuator and electric unit (control unit) ABS actuator and electric unit (control unit)
transmits the vehicle speed signal to BCM via
CAN communication.
BCM also receives the vehicle speed signal
from the combination meter via CAN commu-
nication. BCM compares both signals to de-
tect the vehicle speed.
Refer to
BRC-7, "
Component Parts Location"
for detailed installation location.
3. Transmission range switch Transmission range switch detects the CVT
shift selector lever position.
4. IPDM E/R Starter control relay is used for the engine
starting function. Starter control relay is con-
trolled by IPDM E/R while communicating
with BCM. IPDM E/R se
nds the starter control
relay statu signal to BCM.
5. BCM BCM controls NISSAN VEHICLE IMMOBI-
LIZER SYSTEM-NATS [NVIS (NATS)] and
VEHICLE SECURITY SYSTEM.
When the ignition switch is turned ON, BCM
performs ID verification between BCM and
ECM. If the ID verification result is OK, ECM
can start engine.
Refer to
BCS-77, "
BODY CONTROL SYS-
TEM : Component Parts Location" for de-
tailed installation location.
6. Clutch interlock switch Clutch interlock switch detects that clutch
pedal is depressed, and then transmits ON/
OFF signal to the BCM.
7. Stop lamp switch Stop lamp switch detects that brake pedal is
depressed, and then transmits ON/OFF sig-
nal to the BCM.
8. Main power window and door lock/unlock switch Door lock and unlock switch is integrated into
the main power window and door lock/unlock
switch.
Door lock and unlock switch transmits door
lock/unlock operation signal to BCM.
Refer to
PWC-6, "
Component Parts Loca-
tion".
9. CVT shift selector (park position switch) Park position switch is integrated into the
CVT shift selector and detects that the selec-
tor lever is in the P (park) position, then trans-
mits ON/OFF signal to the BCM and IPDM E/
R.

BCM controls ENGINE START FUNCTION, NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS (NATS) and
VEHICLE SECURITY SYSTEM.
BCM performs the ID verification between BCM and key. If t he ID verification result is OK, ignition switch oper-
ation is available.
Then, when the power supply position is turned ON, BCM performs ID verification between BCM and ECM. If
the ID verification result is OK, ECM can start engine.

SYSTEM DESCRIPTION
NATS (Nissan Anti-Theft System) has the following immobilizer functions:
• Engine immobilizer shows high anti-theft performance to prevent engine from starting by anyone other than
the owner.
• Only a key with key ID registered in BCM and ECM can start engine, and shows high anti-theft performance to prevent key from being copied or stolen.
• Security indicator always flashes with mec hanical key removed condition (key switch: OFF)
• Therefore, NATS warns outsider s that the vehicle is equipped with the anti-theft system.
• If system detects malfunction, security indicator illuminates when ignition switch is turned to ON position.
• If the owner requires, ignition key ID or mechanical key ID can be registered for up to 5 keys.
• During trouble diagnosis or when the following parts have been replaced, and if ignition key is added, regis-
tration
*1 is required:
*1: All keys kept by the owner of the vehi cle should be registered with mechanical key.
-ECM
-BCM
- Ignition key
- Remote keyless entry receiver
• NATS trouble diagnosis, system initialization and additional registration of other mechanical key IDs must be
carried out using CONSULT.
• When NATS initialization has been completed, the ID of the inserted mechanical key or mechanical key IDs can be carried out.
• Possible symptom of NATS malfunction is “Engine cannot start”. Identify the possible causes according to
“Work Flow”, Refer to SEC-139, "
Work Flow".
• If ECM other than Genuine NISSAN is installed, the engine cannot be started. For ECM replacement proce- dure, refer to EC-477, "
Removal and Installation".
