FUNCTION CHART

No.	Component	Function
1	NATS antenna amp.	The ID verification is performed between BCM and transponder integrated into Intelligent Key via NATS antenna amp. when Intelligent Key backside is contacted to power switch in case that Intelligent Key battery is discharged. If the ID verification result is OK, the operation of power switch is available.
2	Power switch	Power switch has push switch inside which detects that power switch is pressed, and then transmits the signal to BCM. BCM changes the power supply position with the operation of power switch. BCM maintains the power supply position status while power switch is not operated.
3	Electric shift control module	Electric shift control module detects the shift position, and then transmits the P position signal to BCM and IPDM E/R. And electric shift control module transmits the P/N position signal to BCM. BCM confirms the shift position with the following 4 signals. P position signal from electric shift control module P/N position signal from electric shift control module P position signal from IPDM E/R (CAN) Shift position signal from VCM (CAN) Refer to "COMPONENT PARTS LOCATION " for detailed installation location.
4	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 PARTS LOCATION " for detailed installation location.
5	Inside key antenna (Instrument center)	Inside key antenna (Instrument center) detects whether Intelligent Key is inside the vehicle or not, and transmits the signal to BCM. Refer to "COMPONENT PARTS LOCATION " for detailed installation location.
6	VCM	VCM controls the vehicle. When power switch is turned to the ON position, BCM starts communication with VCM and performs the ID verification between BCM and VCM. If the verification result is OK, the vehicle can be set to READY. If the verification result is NG, the vehicle can not be set to READY. Refer to "COMPONENT PARTS LOCATION " for detailed installation location.
7	Stop lamp switch	Stop lamp switch detects that brake pedal is depressed, and then transmits the signal to BCM. Refer to "COMPONENT PARTS LOCATION " for detailed installation location.
8	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 PARTS LOCATION " for detailed installation location.
9	IPDM E/R	IPDM E/R has headlamp relays inside. Headlamp relays are used for the vehicle security function. IPDM E/R controls these relays while communicating with BCM. When IPDM E/R receives the alarm request signal from BCM, IPDM E/R activates vehicle security horn and headlamps intermittently. Refer to "COMPONENT PARTS LOCATION " for detailed installation location.
10	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 power switch is in any position other than ON to warn that NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS [NVIS (NATS)] is on board.
11	BCM	BCM controls INTELLIGENT KEY SYSTEM (READY SET FUNCTION), NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS [NVIS (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 power switch is pressed. If the ID verification result is OK, power switch operation is available. Then, when the power switch is turned to the ON position, BCM performs ID verification between BCM and VCM. If the ID verification result is OK, vehicle can be set to READY. Refer to "BODY CONTROL SYSTEM : COMPONENT PARTS LOCATION " for detailed installation location.
12	Door lock and unlock switch	Door lock and unlock switch is integrated into the power window main switch and front power window switch (passenger side). Door lock and unlock switch transmits door lock/unlock operation signal to BCM.
13	Outside door handle (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. Front door request switch transmits door lock/unlock request signal to BCM.
14	Door key cylinder switch	Door key cylinder switch detects door LOCK/UNLOCK operation using mechanical key, and then transmits door lock/unlock operation signal to BCM.
15	Front door switch (Driver side)	Door switch detects door open/close condition, and then transmits ON/OFF signal to BCM.
16	Rear door switch LH	Door switch detects door open/close condition, and then transmits ON/OFF signal to BCM.
17	Back door opener switch assembly	Back door opener switch and back door request switch are integrated into back door switch assembly. Back door opener switch transmits back door opening operation signal to BCM. Back door request switch transmits door lock/unlock request signal to BCM.
18	Back door lock assembly	Back door switch is integrated into back door lock assembly. Back door switch detects back door open/close condition, and then transmits ON/OFF signal to BCM.
19	Outside key antenna (Rear bumper)	Outside key antenna (Rear bumper) detects whether Intelligent Key is within the detection area or not, and then transmits signal to BCM. Refer to "COMPONENT PARTS LOCATION " for detailed installation location.
20	Inside key antenna (Luggage room)	Inside key antenna (Luggage room) detects whether Intelligent Key is inside the vehicle or not, and transmits the signal to BCM. Refer to "COMPONENT PARTS LOCATION " for detailed installation location.
21	Rear door switch RH	Door switch detects door open/close condition, and then transmits ON/OFF signal to BCM.
22	Inside key antenna (Rear seat)	Inside key antenna (Rear seat) detects whether Intelligent Key is inside the vehicle or not, and then transmits the signal to BCM. Refer to "COMPONENT PARTS LOCATION " for detailed installation location.
23	Front door switch (Passenger side)	Door switch detects door open/close condition, and then transmits ON/OFF signal to BCM.
24	Outside door handle (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. Front door request switch transmits door lock/unlock request signal to BCM.
