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)

NISSAN VEHICLE IMMOBILIZER SYSTEM-NAT S : CVT Shift Selector (Park Position
Switch)
INFOID:0000000012430443
Park position switch detects that CVT shift selector is in the P (Park) position and then transmits the signal to
BCM and IPDM E/R.
BCM confirms the CVT shift selector position with the following 5 signals:
• P (Park) position signal from CVT shift selector (park position switch)
• P/N position signal from TCM
• P (Park) position signal from IPDM E/R (CAN)
• P/N position signal from IPDM E/R (CAN)
• P/N position signal from TCM (CAN)
IPDM E/R confirms the CVT shift selector position with the following 3 signals:
• P (Park) position signal from CVT shift selector (park position switch)
• P/N position signal from TCM
• P/N position signal from BCM (CAN)
NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS : BCMINFOID:0000000012430444
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.
NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS : ECMINFOID:0000000012430445
ECM controls the engine.
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.
NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS : IPDM E/RINFOID:0000000012430446
IPDM E/R has the starter control relay inside. Starter control relay is used for the engine starting function.
IPDM E/R controls this relay while communicating with BCM.
NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS : Combination MeterINFOID:0000000012430447
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.
10. Front door switch LH Door switch detects door open/close condi-
tion and then transmits ON/OFF signal to
BCM.
11. Rear door switch LH Door switch detects door open/close condi-
tion and then transmits ON/OFF signal to
BCM.
12. Ignition switch Input ignition switch ON/OFF condition to
BCM.
13. NATS antenna amp. ID verification is performed between the BCM
and the transponder integrated into the key
via the NATS antenna amp.
14. Remote keyless entry receiver Remote keyless entry receiver receives but-
ton operation signal and key ID signal then
transmits them to the BCM.
No.
