No.	Component	Function
	TCU	TCU transmits engine start signal to BCM when engine start request is received from Infiniti Connection^TM data center. TCU transmits panic alarm request signal to BCM when panic alarm request is received from Infiniti Connection^TM data center.
	Stop lamp switch	Stop lamp switch detects that brake pedal is depressed, and then transmits ON/OFF signal to BCM. Refer to COMPONENT LOCATION for detailed installation location.
	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 communication. BCM compares both signals to detect the vehicle speed. Refer to COMPONENT LOCATION for detailed installation location.
	TCM (CVT models)	TCM receives the shift position signal from transmission range switch, and then transmits the P/N position signal to BCM via CAN communication. BCM confirms the selector lever position with the following 4 signals. P position signal from CVT shift selector (detention switch) P position signal from IPDM E/R (CAN) Neutral position signal from IPDM E/R (CAN) P/N position signal from TCM (CAN) IPDM E/R confirms the selector lever position with the following 2 signals. P/N position signal from transmission range switch P/N position signal from BCM (CAN) Refer to COMPONENT LOCATION for detailed installation location.
	Transmission range switch (CVT models)	Transmission range switch detects the selector lever position, and then transmits the P/N position signal to IPDM E/R. BCM confirms the CVT shift selector position with the following 4 signals. P position signal from CVT shift selector (detention switch) P position signal from IPDM E/R (CAN) Neutral 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 2 signals. P/N position signal from transmission range switch P/N position signal from BCM (CAN) Refer to COMPONENT LOCATION for detailed installation location.
	Park/neutral position switch (M/T models)	Park/neutral position switch detects that shift lever is in the neutral position, and then transmits ON/OFF signal to IPDM E/R.
	Horn high	Horn high operate for warning vehicle surroundings when VEHICLE SECURITY SYSTEM operates.
	Hood switch	Refer to HOOD SWITCH .
	ECM	ECM controls the engine. When ignition switch 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 NG, the engine cannot start. Refer to COMPONENT LOCATION for detailed installation location.
	Horn low	Horn low operate for warning vehicle surroundings when VEHICLE SECURITY SYSTEM operates.
	IPDM E/R	Starter relay are integrated in IPDM E/R, and used for the engine starting function. Starter control relay is controlled by BCM, and starter relay is controlled by IPDM E/R while communicating with BCM. IPDM E/R sends the starter control relay/starter relay status signal to BCM. Refer to COMPONENT LOCATION for detailed installation location.
	Clutch interlock switch (M/T models)	Clutch interlock switch detects that clutch pedal is depressed, and transmits ON/OFF signal to BCM.
	Clutch pedal position switch (M/T models)	Clutch pedal position switch detects that clutch pedal is depressed, and then transmits ON/OFF signal to BCM.
	BCM	BCM controls INTELLIGENT KEY SYSTEM (ENGINE START FUNCTION), NISSAN VEHICLE IMMOBILIZER SISTEM (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, ignition switch operation is available. Then, when the ignition switch is turned ON, BCM performs ID verification between BCM and ECM. If the ID verification result is OK, ECM can start engine. Refer to COMPONENT LOCATION for detailed installation location.
	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 ignition switch is in any position other than ON to warn that NISSAN VEHICLE IMMOBILIZER SISTEM (NATS) is on board.
	CVT shift selector (detention switch) (CVT models)	Detention switch is integrated into CVT shift sector, and detects that selector lever is locked in the P position, then transmits ON/OFF signal to BCM.
	Power window main switch (door lock and unlock switch)	Door lock and unlock switch transmits door lock/unlock signal operation to BCM.
	Outside key antenna (driver side)	Outside key antenna and door request switch are integrated into outside door handle. Outside key antenna detects whether Intelligent Key is within the detection area or not, and then transmits signal to BCM. Refer to COMPONENT LOCATION for detailed installation location.
	Front door request switch (driver side)	Front door request switch transmits door lock/unlock request signal to BCM.
	Front door switch (driver side)	Door switch detects door open/close condition and then transmits ON/OFF signal to BCM.
	Rear door switch LH	Door switch detects door open/close condition and then transmits ON/OFF signal to BCM.
	Inside key antenna (luggage room)	Inside key antenna (luggage room) detects whether Intelligent Key is inside the vehicle, and transmits the signal to BCM. Refer to COMPONENT LOCATION for detailed installation location.
	Remote keyless entry receiver (Rear)	Remote keyless entry receiver (Rear) receives each button operation signal and electronic key ID signal from Intelligent Key, and then transmits the signal to BCM. Refer to COMPONENT LOCATION for detailed installation location.
	Outside key antenna (rear bumper)	Detects whether or not Intelligent Key is within the outside key antenna detection area. Refer to COMPONENT LOCATION for detailed installation location.
	Back door lock assembly	Back door switch is integrated into back door look assembly. Back door switch detects back door open/close condition, and then transmits ON/OFF signal to BCM. Refer to COMPONENT LOCATION for detailed installation location.
	Back door opener request switch	Back door opener request switch transmits door lock/unlock request signal to BCM. Refer to COMPONENT LOCATION for detailed installation location.
	Rear door switch RH	Door switch detects door open/close condition and then transmits ON/OFF signal to BCM.
	Front door switch (Passenger side)	Door switch detects door open/close condition and then transmits ON/OFF signal to BCM.
	Outside key antenna (passenger side)	Outside key antenna and door request switch are integrated into outside door handle. Outside key antenna detects whether Intelligent Key is within the detection area or not, and then transmits signal to BCM. Refer to COMPONENT LOCATION for detailed installation location.
	Front door request switch (passenger side)	Front door request switch transmits door lock/unlock request signal to BCM.
	Inside key antenna (instrument center)	Inside key antenna (instrument center) detects whether Intelligent Key is inside the vehicle, and transmits the signal to BCM. Refer to COMPONENT LOCATION for detailed installation location.
