CVT Shift Selector (Park Position Switch)

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

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

ECM controls the engine.

When power supply position is turned ON, BCM starts communication with ECM and performs the ID verification 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

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

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

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.

Door Switch

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

Outside Key Antenna

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

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

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

Intelligent Key

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

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

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

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 controlled 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

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