• P/N position signal from TCM (CAN)
IPDM E/R confirms the A/T shift selector position with the following 3 signals.
• P position signal from A/T shift selector (detention switch)
• P/N position signal from transmission range switch
• P/N position signal from BCM (CAN)

BCM

INFOID:0000000006038461

BCM controls INTELLIGENT KEY SYSTEM (ENGINE START FUNCTION) and NISSAN ANTI-THEFT SYS-
TEM (NATS).
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 switch 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.

ECM

INFOID:0000000006038462

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/R

INFOID:0000000006038463

Starter control relay and starter relay are used for the engine starting function. Starter relay is located on dash
side (LH) and controlled by BCM. Starter control relay is integrated in IPDM E/R and controlled by IPDM E/R
while communicating with BCM. IPDM E/R sends the starter control relay and starter relay status signal to
BCM. 

NATS Antenna Amp.

INFOID:0000000006038464

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 ignition switch in case that Intelligent Key battery is
discharged. If the ID verification result is OK, the release of steering lock and the operation of starting engine
is available.

TCM

INFOID:0000000006038465

TCM transmits the shift position signal (P/N position) to BCM via CAN communication.
BCM confirms the A/T shift selector position with the following 5 signals.
• P position signal from A/T shift selector (detention switch)
• P/N position signal from transmission range switch
• P 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 A/T shift selector position with the following 3 signals.
• P position signal from A/T shift selector (detention switch)
• P/N position signal from transmission range switch
• P/N position signal from BCM (CAN)

Combination Meter

INFOID:0000000006038466

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 commu-
nication. BCM compares both signals to detect the vehicle speed.

Door Switch

INFOID:0000000006038467

Door switch detects door open/close condition and then transmits ON/OFF signal to BCM.

Inside Key Antenna

INFOID:0000000006038469

Inside key antenna detects whether Intelligent Key is inside the vehicle, and transmits the signal to BCM.

SEC-10

< SYSTEM DESCRIPTION >

[WITH INTELLIGENT KEY SYSTEM]

COMPONENT PARTS

Three inside key antennas are installed in the instrument center, console and luggage room.

Intelligent Key

INFOID:0000000006038470

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 performs door lock/unlock operation
and push-button ignition switch operation.

Push-button Ignition Switch

INFOID:0000000006038472

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.

Remote Keyless Entry Receiver

INFOID:0000000006038473

Remote keyless entry receiver receives each button operation signal and electronic key ID signal from Intelli-
gent Key, and then transmits the signal to BCM.

Security Indicator Lamp

INFOID:0000000006038474

Security indicator lamp is located on combination meter.
Security indicator lamp blinks when power supply position is in any position except the ON position to warn
that Nissan Anti-Theft System (NATS) is on board.

Starter Control Relay

INFOID:0000000006038477

Starter control relay and starter relay are used for the engine starting function. Starter relay is located on dash
side (LH) and controlled by BCM. Starter control relay is integrated in IPDM E/R and controlled by IPDM E/R
while communicating with BCM. IPDM E/R sends the starter control relay and starter relay status signal to
BCM. 

Starter Relay

INFOID:0000000006038478

Starter control relay and starter relay are used for the engine starting function. Starter relay is located on dash
side (LH) and controlled by BCM. Starter control relay is integrated in IPDM E/R and controlled by IPDM E/R
while communicating with BCM. IPDM E/R sends the starter control relay and starter relay status signal to
BCM. 

Steering Lock Relay

INFOID:0000000006038479

Steering lock relay is located on dash side (LH), and controlled by IPDM E/R to supply power source for steer-
ing lock unit.
When IPDM E/R receives the steering lock relay ON request signal from BCM, IPDM E/R turns ON steering
lock relay and then transmits the steering lock relay condition signal to BCM.

Steering Lock Unit

INFOID:0000000006038480

Steering lock unit performs steering lock/unlock operation on request from BCM, and power source is supplied
from steering lock relay controlled by IPDM E/R.
When push-button ignition switch is pressed while the Intelligent Key is inside the vehicle, BCM performs the
ID verification with steering lock unit. Steering lock unit releases the steering lock based on the result of the ID
verification.
Steering lock unit has 2 switches (steering lock status switch and steering unlock status switch) inside. BCM
judges the steering lock/unlock condition by comparing these switch signals and steering lock unit status sig-
nal transmitted from IPDM E/R via CAN communication.

Stop Lamp Switch

INFOID:0000000006038481

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

Transmission Range Switch

INFOID:0000000006038482

Transmission range switch is integrated in A/T assembly, and detects the A/T shift selector position.
