After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and a no-start condition.

Component Description
INFOID:0000000009461065
CVT Shift Selector (P ark Position Switch)INFOID:0000000009461066
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 sele ctor 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)
BCMINFOID:0000000009461067
BCM controls INTELLIGENT KE Y SYSTEM (ENGINE START FUNCTIO N), NISSAN VEHICLE IMMOBI-
LIZER SYSTEM-NATS [NVIS (NATS) ], and VEHICLE SECURITY SYSTEM.
BCM performs the ID verification between BCM and Intelligent Key when the Intelligent Key is carried into the
detection area of inside key antenna and push-button ignition swit ch is pressed. If the ID verification result is
OK, push-button ignition switch operation 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.
ECMINFOID:0000000009461068
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 NG, the engine can not start.
IPDM E/RINFOID:0000000009461069
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 contro ls these relays while communicating with BCM.
NATS Antenna Amp.INFOID:0000000009461070
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 i gnition switch in case that Intelligent Key battery is
discharged. If the ID verification result is OK, the operation of starting engine is available.
TCMINFOID:0000000009461071
TCM transmits the shift position signal (P/N position) to BCM and IPDM E/R. And further, TCM transmits the
shift position signal (P/N position) to BCM via CAN communication.
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 select or 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)
Combination MeterINFOID:0000000009461072
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:0000000009461073
Door switch detects door open/close conditi on and then transmits ON/OFF signal to BCM.
Outside Key AntennaINFOID:0000000009461074
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.
Hood SwitchINFOID:0000000009461075
Hood switch detects that hood is open/closed, and then trans mits the signal to IPDM E/R. IPDM E/R transmits
hood switch signal to BCM via CAN communication.
Inside Key AntennaINFOID:0000000009461076
Inside key antenna detects whether Intelligent Key is inside the vehicle and transmits the signal to BCM.
Two inside key antennas are installed in the front console and rear parcel shelf.
Remote Keyless Entry ReceiverINFOID:0000000009461077
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:0000000009461078
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 BCM, the driver can perform, remote start, door lock/
unlock operation, remote trunk, panic alarm and push-button ignition switch operation.

SYSTEM
NOTE:
Refer to DLK-23, "INTELLIGENT KEY 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 NVIS (NATS) ID verifi cation] is integrated into the Intelligent Key.
In that case, the NVIS (NATS) ID verification can be performed when Intelligent Key backside is con-
tacted to push-button ignition switch. 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 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. BCM detects that the selector leve r position and brake pedal operating condition.
7. BCM transmits the starter request signal to IPDM E/R and turns the starter relay in IPDM E/R ON if BCM judges that the engine start condition* is satisfied.
8. IPDM E/R turns the starter control relay ON when receiving the starter request signal.
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 in the combina-
tion meter illuminates. At that ti me, the engine cannot be started.
10. When BCM receives feedback signal from ECM indicati ng 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 autom atically within 5 seconds.)
CAUTION:
When the Intelligent Key is carri ed outside of the 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 the tabl e below “POWER SUPPLY POSITION CHANGE TABLE BY
PUSH-BUTTON 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, the NVIS (NATS) ID verification between transponder in Intelligent
Key and BCM is performed when Intelligent Key backside is contacted to push-button ignition switch. If the
verification result is OK, engine can be started.
POWER SUPPLY POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH OPERA-
TION
The power supply position changing operation c an be performed with the following operations.
NOTE:
• When an Intelligent Key is within the detection area of inside key antenna and 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 operating condition
- Selector lever position
- Vehicle speed
Vehicle speed: less than 4 km/h (2.5 MPH)
