CVT Shift Selector (Park Position Switch)

INFOID:0000000009268353

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)

BCM

INFOID:0000000009268354

BCM controls INTELLIGENT KEY SYSTEM (ENGINE START FUNCTION), NISSAN VEHICLE IMMOBI-

LIZER SYSTEM-NATS (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 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:0000000009268355

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.

IPDM E/R

INFOID:0000000009268356

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 controls these relays while communicating with BCM.

NATS Antenna Amp.

INFOID:0000000009268357

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 operation of starting engine is available.

Combination Meter

INFOID:0000000009268358

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:0000000009268359

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

Outside Key Antenna

INFOID:0000000009268360

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.

Inside Key Antenna

INFOID:0000000009268361

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

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

Remote Keyless Entry Receiver

INFOID:0000000009268362

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.

Intelligent Key

INFOID:0000000009268363

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 liftgate, panic alarm and push-button ignition switch operation.

Push-button Ignition Switch

INFOID:0000000009268364

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.

Security Indicator Lamp

INFOID:0000000009268365

Security indicator lamp is located on combination meter.

Security indicator lamp blinks when power supply position is any position other than ON to warn that NISSAN

VEHICLE IMMOBILIZER SYSTEM-NATS  (NATS) is on board.

Starter Relay

INFOID:0000000009268366

Engine starting system functions by controlling both starter relay and starter control relay.

Both relays are integrated in IPDM E/R. Starter relay is controlled by BCM, and starter control relay is con-

trolled by IPDM E/R on request from BCM.

IPDM E/R transmits starter relay and starter control relay status signal to BCM via CAN communication.

Stop Lamp Switch

INFOID:0000000009268367

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

Transmission Range Switch

INFOID:0000000009268368

Transmission range switch is integrated in CVT assembly, and detects the CVT shift selector position.

TCM receives the transmission range switch signal and then transmits the P/N position 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)
