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.

NISSAN ANTI-THEFT SYSTEM : System DescriptionINFOID:0000000012430342
SYSTEM DIAGRAM
SYSTEM DESCRIPTION
• The Nissan Anti-Theft System (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 NATS ID verification is performed between the transponder integrated with Intelligent Key
and BCM via NATS antenna amp. when the Intelligent Ke y backside is contacted to push-button ignition
switch while brake pedal is depressed. If the verifica tion result is OK, the engine start operation can be per-
formed by the push-button ignition switch operation.
• Locate the security indicator lamp and always blinks it when the ignition switch is in any position except ON
to warn that the vehicle is equipped with Nissan Anti-Theft System (NATS).
• Up to 4 Intelligent Keys can be registered (including the standard ignition key) upon request from the owner.
• When replacing ECM, BCM or Intelligent Key, the spec ified procedure (Initialization and registration) using
CONSULT is required.
• For initialization and registration of Intelligent Keys, refer to CONSULT Immobilizer mode and follow the on-
screen instructions.
• Possible symptom of NATS malfunction is “Engine c an not start”. This symptom also occurs because of
other than NATS malfunction, so start the trouble diagnosis according to SEC-46, "
Work Flow".
• If ECM other than genuine part is installed, the engine cannot be started. For ECM replacement procedure, refer to EC-477, "
Removal and Installation".

SYSTEM
PRECAUTIONS FOR KEY REGISTRATION
• The ID registration is a procedure that erases the cu
rrent NATS ID once, and then registers a new ID. There-
fore 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 IDs (NATS
ID and Intelligent Key ID).
SECURITY INDICATOR LAMP
• Security indicator lamp warns that the vehicle is equipped with NATS.
• Security indicator lamp always blinks when the i gnition switch is in 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 the BCM activates NATS antenna amp. that is located behind push-button ignition switch.
2. When Intelligent Key (transponder built-in) backsi de is contacted to push-button ignition switch, BCM
starts NATS ID verification between BCM and Intelligent Key (transponder built-in) via NATS antenna
amp.
3. When NATS ID verification result is OK, buzzer in combination meter sounds and BCM transmits 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. IPDM E/R turns the starter control relay ON for engine starting in advance.
7. BCM detects that the selector leve r position and brake pedal operation condition.
8. BCM transmits 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.
10. When BCM receives feedback signal from ECM indica ting that the engine is started, BCM transmits a
stop signal to IPDM E/R and stops 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 “IGN ITION SWITCH POSITION CHANGE TABLE BY PUSH-BUT-
TON IGNITION SWITCH OPERATION” below.
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)
