COMPONENT PARTS

5.

Inside key antenna (Instrument 
center)

Inside key antenna (Instrument center) detects whether Intelligent Key is inside the vehicle 
or not, and transmits the signal to BCM.
Refer to 

DLK-17, "Inside Key Antenna (Instrument Center)"

 for detailed installation location.

6.

VCM

• VCM controls the vehicle. When power switch is turned to the ON position, BCM starts 

communication with VCM and performs the ID verification between BCM and VCM.
If the verification result is OK, the vehicle can be set to READY. If the verification result is 
NG, the vehicle can not be set to READY.

• VCM detects the shift position, and then transmits the P position signal to BCM and IPDM 

E/R. And VCM transmits the P/N position signal to BCM.

• BCM confirms the shift position with the following 4 signals.
- P position signal from electric shift selector
- P/N position signal from electric shift selector
- P position signal from IPDM E/R (CAN)
Refer to 

EVC-15, "Component Parts Location"

 for detailed installation location.

7.

Stop lamp switch

Stop lamp switch detects that brake pedal is depressed, and then transmits the signal to 
BCM.
Refer to 

BRC-10, "Component Parts Location"

 for detailed installation location.

8.

ABS actuator and electric unit 
(control unit)

ABS actuator and electric unit (control unit) transmits the vehicle speed signal to BCM via 
CAN communication.
BCM also receives the vehicle speed signal from combination meter via CAN communica-
tion. BCM compares both signals to detect the vehicle speed.
Refer to 

BRC-10, "Component Parts Location"

 for detailed installation location.

9.

IPDM E/R

IPDM E/R has headlamp relays inside. Headlamp relays are used for the vehicle security 
function. IPDM E/R controls these relays while communicating with BCM.
When IPDM E/R receives the alarm request signal from BCM, IPDM E/R activates vehicle 
security horn and headlamps intermittently.
Refer to 

PCS-6, "Component Parts Location"

 for detailed installation location.

10.

Combination meter

Combination meter transmits the vehicle speed signal to BCM via CAN communication.
BCM also receives the vehicle speed signal from ABS actuator and electric unit (control unit) 
via CAN communication. BCM compares both signals to detect the vehicle speed.
Security indicator lamp is located on combination meter.
Security indicator lamp blinks when power switch is in any position other than ON to warn 
that NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS [NVIS (NATS)] is on board.
Refer to 

MWI-6, "METER SYSTEM : Component Parts Location"

 for detailed installation lo-

cation.

Refer to 

DLK-19, "Door Lock and Unlock Switch"

 for detailed installation location.

12.

Front outside handle LH

Outside key antenna and door request switch are integrated into the front outside handle LH.

SYSTEM DESCRIPTION 

• The READY set function of Intelligent Key system makes it possible to set the vehicle to READY without

using the key, based on the electronic ID verification. The electronic ID verification is performed between

BCM and Intelligent Key when the power switch is pressed while the Intelligent Key is within the detection

area of inside key antenna.

NOTE:

The driver should carry the Intelligent Key at all times.

• Intelligent Key has 2 IDs [Intelligent Key ID and NVIS (NATS) ID]. It can perform the door lock/unlock opera-

tion and the power switch operation when the registered Intelligent Key is carried.

• If the ID is successfully verified, power switch operation can be available and the vehicle can be set to

READY.

• Up to 4 Intelligent Keys can be registered upon request from the customer.

NOTE:

Refer to 

DLK-24, "INTELLIGENT KEY SYSTEM : System Description"

 for any functions other than the

READY set function of Intelligent Key system.

PRECAUTIONS FOR INTELLIGENT KEY SYSTEM

The transponder [the chip for NVIS (NATS) ID verification] is integrated into the Intelligent Key. There-

fore, ID verification cannot be performed using mechanical key only.

When Intelligent Key battery is discharged, the NVIS (NATS) ID verification can be performed by oper-

ating power switch after contacting Intelligent Key backside to power switch. If verification result is

OK, the vehicle can be set to READY.

OPERATION WHEN INTELLIGENT KEY IS CARRIED

1. When the power switch is pressed, 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 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 ON power supply signal to IPDM E/R if the verification results are

OK.

5. IPDM E/R turns the ignition relay ON to start ON power supply.
6. BCM detects that the shift position and brake pedal operating condition.
7. BCM transmits READY signal to VCM if BCM judges that the READY set condition* is satisfied.

*: For READY set condition, refer to “READY SET CONDITION TABLE BY POWER SWITCH OPERA-

TION” below.

NOTE:

• If a malfunction is detected in the Intelligent Key system, “I-KEY system fault” on information display

appears. In this case, BCM does not transmits READY signal.

• When the Intelligent Key is carried outside of the vehicle (inside key antenna detection area) while the

power switch position is ACC or ON, BCM does not transmits READY signal even if READY set condi-

tion* is satisfied.

8. When BCM receives feedback signal from VCM indicating that the vehicle is set to READY, BCM stops

transmitting READY signal.

OPERATION RANGE

Vehicle can be set to READY when Intelligent Key is inside the vehicle. However, sometimes vehicle may not

be set to READY when Intelligent Key is on instrument panel or in glove box.
