COMPONENT PARTS
When power supply position is turned ON, BCM starts
communication with ECM and performs the ID verifica-
tion between BCM and ECM.
If the verification result is OK, the engine can start. If the verification result is invalid, the engine can not start.
IPDM E/RINFOID:0000000012430328
IPDM E/R has the starter relay and starter control relay inside. Starter relay and starter control relay are used
for the engine starting function. IPDM E/R controls these relays while communicating with BCM.
NATS Antenna Amp.INFOID:0000000012430329
The ID verification is performed between BCM and transponder in Intelligent Key via NATS antenna amp.
when Intelligent Key backside is contacted to push-button igni tion switch in case that Intelligent Key battery is
discharged. If the ID verification result is OK, the operation of starting engine is available.
Combination MeterINFOID:0000000012430330
Combination meter transmits the vehicle speed signal to BCM via CAN communication.
BCM also receives the vehicle speed signal from ABS ac tuator and electric unit (control unit) via CAN commu-
nication. BCM compares both signals to detect the vehicle speed.
Door SwitchINFOID:0000000012430331
Door switch detects door open/close conditi on and then transmits ON/OFF signal to BCM.
Outside Key AntennaINFOID:0000000012430332
Outside key antenna detects whether Intelligent Key is outside the vehicle and transmits the signal to BCM.
Three outside key antennas are installed in the front outside handle LH, front outside handle RH and rear
bumper.
Inside Key AntennaINFOID:0000000012430333
Inside key antenna detects whether Intelligent Key is inside the vehicle and transmits the signal to BCM.
Three inside key antennas are installed in the instrument center, console and trunk room.
Remote Keyless Entry ReceiverINFOID:0000000012430334
Remote keyless entry receiver receives each button oper ation signal and electronic key ID signal from Intelli-
gent Key and then transmits the signal to BCM.
Intelligent KeyINFOID:0000000012430335
Each Intelligent Key has an individual electronic ID and transmits the ID signal by request from BCM.
Carrying the Intelligent Key whose ID is registered in BC M, the driver can perform, remote start, door lock/
unlock operation, remote liftgate, panic alarm and push-button ignition switch operation.
Push-button Ignition SwitchINFOID:0000000012430336
Push-button ignition switch detects that push-button is pressed and then transmits the signal to BCM. BCM
changes the power supply position with the operation of push-button ignition switch. BCM maintains the power
supply position status while push-button is not operated.
Security Indicator LampINFOID:0000000012430337
Security indicator lamp is located on combination meter.
Security indicator lamp blinks when power supply positi on is any position other than ON to warn that NISSAN
VEHICLE IMMOBILIZER SYSTEM-NATS (NATS) is on board.
Starter RelayINFOID:0000000012430338
Engine starting system functions by controlling both starter relay and starter control relay.
Starter relay is controlled by BCM, and starter contro l relay is controlled by IPDM E/R on request from BCM.
IPDM E/R transmits starter relay and starter control relay status signal to BCM via CAN communication.

Refer to SEC-15, "NISSAN ANTI-THEFT 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 NATS ID verification) is integrated into the Intelligent Key. (For the con-
ventional models, it is integrated into the mechanical key.) Therefore, ID verification cannot be per-
formed by mechanical key only.
In that case, NATS ID verification can be perfor med when Intelligent Key backside is contacted to
push-button ignition switch while brake pedal is depressed. 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 i gnition power supply ON signal to IPDM E/R.
5. IPDM E/R turns the ignition relay ON and starts the ignition power supply.
6. IPDM E/R turns the starter control relay ON for engine starting in advance.
7. BCM detects the selector lever position and brake pedal operation condition.
8. BCM transmits the starter request signal to IPDM E/R and turns the starter relay ON if BCM judges that the engine start condition* is satisfied.
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 on 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 aut omatically within 5 seconds.)
CAUTION:
When the Intelligent Key is carried outside of th e 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 “IGNIT ION 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 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, NATS ID verification between transponder in Intelligent Key and
BCM is performed when Intelligent Key backside is cont acted to push-button ignition switch while brake pedal
is depressed. If the verification result is OK, engine can be started.
IGNITION SWITCH POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH OPERA-
TION
The ignition switch position can be changed by the following operations:
NOTE:
• When an Intelligent Key is within the detection area of inside key antenna or 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 operation condition
- Selector lever position
- Vehicle speed
Vehicle speed: less than 4 km/h (2.5 MPH)

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".
