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)

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.
