No.	Component		Function
	Trunk lid opener request switch		Trunk lid opener request switch detects open operation of trunk lid and transmits trunk lid opener request signal to BCM.
	Trunk lid lock assembly (trunk room lamp switch)		Trunk room lamp switch is integrated into trunk lid lock assembly. Trunk room lamp switch detects trunk lid open/close condition and then transmits ON/OFF signal to BCM.
	Outside key antenna (rear bumper)		Outside key antenna detects whether Intelligent Key is within the detection area or not, and then transmits signal to BCM. Refer to Component Location .
	Rear door switch RH		Door switch detects door open/close condition and then transmits ON/OFF signal to BCM.
	Outside handle assembly (passenger side)	One touch unlock sensor	One touch unlock sensor detects user hold outside handle operation and transmits one touch unlock sensor signal to BCM. Refer to Component Location .
		Door request switch	Door request switch (passenger side) detected door lock/unlock operation and transmits door request switch signal to BCM.
	Door switch (passenger side)		Door switch detects door open/close condition and then transmits ON/OFF signal to BCM.
	Inside key antenna (console)		Inside key antenna (console) detects whether Intelligent Key is inside the vehicle, and transmits the signal to BCM. Refer to Component Location .
	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. Refer to Component Location .
	IPDM E/R		Starter control relay and starter relay are integrated in IPDM E/R, and used for the engine starting function. Starter relay is controlled by BCM, and starter control relay is controlled by IPDM E/R while communicating with BCM. IPDM E/R sends the starter control relay and starter relay status signal to BCM. Refer to Component Location .
	BCM		BCM controls INTELLIGENT KEY SYSTEM (ENGINE START FUNCTION), INFINITI VEHICLE IMMOBILIZER SYSTEM (IVIS) 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 .
	Inside key antenna (instrument lower)		Inside key antenna (instrument lower) detects whether Intelligent Key is inside the vehicle, and transmits the signal to BCM. Refer to Component Location .
	Horn low		Horn low operate for warning vehicle surroundings when VEHICLE SECURITY SYSTEM operates.
	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 .
	A/T assembly (TCM)		TCM detects the selector lever position, and then transmits the P/N position signal to BCM and IPDM E/R. BCM confirms the A/T shift selector position with the following 4 signals. P position signal from A/T shift selector (detention switch) P/N position signal from TCM Interlock/PNP switch signal from IPDM E/R (CAN) P/N position signal from HPCM (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 HPCM (CAN) P/N position signal from BCM (CAN) Refer to Component Location .
	Horn high		Horn high operate for warning vehicle surroundings when VEHICLE SECURITY SYSTEM operates.
	Hood switch		Refer to Component Description .
	Stop lamp switch		Stop lamp switch detects that brake pedal is depressed, and then transmits ON/OFF signal to BCM. Refer to Component 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 .
	TCU		TCU transmits engine start signal to BCM when engine start request signal is received from Infiniti Connection? data center. Refer to Component Location .
	Power window main switch (door lock and unlock switch)		Door lock and unlock switch transmits door lock/unlock signal operation to BCM.
	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 INFINITI VEHICLE IMMOBILIZER SYSTEM (IVIS) is on board.
	Door switch (driver side)		Door switch detects door open/close condition and then transmits ON/OFF signal to BCM.
	Outside handle assembly (driver side)	One touch unlock sensor	One touch unlock sensor detects user hold outside handle operation and transmits one touch unlock sensor signal to BCM. Refer to Component Location .
		Door request switch	Door request switch (driver side) detected door lock/unlock operation and transmits door request switch signal to BCM.
	A/T shift selector (detention switch)		Detention switch is integrated into A/T shift sector, and detects that selector lever is locked in the P position, then transmits ON/OFF signal to BCM and IPDM E/R.
	Rear door switch LH		Door switch detects door open/close condition and then transmits ON/OFF signal to BCM.
	Inside key antenna (trunk room)		Inside key antenna (trunk room) detects whether Intelligent Key is inside the vehicle, and transmits the signal to BCM. Refer to Component Location .
	Push-button ignition switch		Push-button ignition switch has push switch inside which detects that push-button ignition switch is pressed, and then transmits ON/OFF signal to BCM. BCM change the ignition switch position with the operation of push-button ignition switch. BCM maintains the ignition switch position status while push-button ignition switch is not operated.
	NATS antenna amp.		Refer to Component Description .
