No.	Component	Function
1	Inside key antenna (Luggage room)	Inside key antenna (Luggage room) detects whether Intelligent Key is inside the vehicle or not, and then transmits the signal to BCM. Refer to "DOOR LOCK SYSTEM: COMPONENT PARTS LOCATION " for detailed installation location.
2	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 "DOOR LOCK SYSTEM: COMPONENT PARTS LOCATION " for detailed installation location.
3	Inside key antenna (Console)	Inside key antenna (Console) detects whether Intelligent Key is inside the vehicle or not, and then transmits the signal to BCM. Refer to "DOOR LOCK SYSTEM: COMPONENT PARTS LOCATION " for detailed installation location.
4	Inside key antenna (Instrument center)	Inside key antenna (Instrument center) detects whether Intelligent Key is inside the vehicle or not, and then transmits the signal to BCM. Refer to "DOOR LOCK SYSTEM: COMPONENT PARTS LOCATION " for detailed installation location.
5	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.
6	Stop lamp relay	Stop lamp relay is used to send the stop lamp switch signal to BCM. Refer to "CVT CONTROL SYSTEM: COMPONENT PARTS LOCATION " for detailed installation location.
7	TCM	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 5 signals. P position signal from CVT shift selector (detention switch) P/N position signal from TCM P 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 selector lever position with the following 3 signals. P position signal from CVT shift selector (detention switch) P/N position signal from TCM P/N position signal from BCM (CAN) Refer to "CVT CONTROL SYSTEM: COMPONENT PARTS LOCATION " for detailed installation location.
8	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 can not start. Refer to "ENGINE CONTROL SYSTEM: COMPONENT PARTS LOCATION " for detailed installation location.
9	NATS antenna amp.	Refer to "NATS Antenna Amp. ".
10	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 changes 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.
11	Stop lamp switch	Stop lamp switch detects that brake pedal is depressed, and then transmits ON/OFF signal to BCM. Refer to "CVT CONTROL SYSTEM: COMPONENT PARTS LOCATION " for detailed installation location.
12	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 "IPDM E/R: COMPONENT PARTS LOCATION " for detailed installation location.
13	BCM	BCM controls INTELLIGENT KEY SYSTEM (ENGINE START 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 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 "BODY CONTROL SYSTEM: COMPONENT PARTS LOCATION " for detailed installation location.
14	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 SYSTEM-NATS [NVIS (NATS)] is on board. Refer to "METER SYSTEM: COMBINATION METER ".
15	Power window main switch	Door lock and unlock switch is integrated into the power window main switch. Door lock and unlock switch transmits door lock/unlock operation signal to BCM. Refer to "POWER WINDOW MAIN SWITCH " (front window anti-pinch) or "POWER WINDOW MAIN SWITCH " (driver side window anti-pinch).
16	Front door outside handle assembly LH	Outside key antenna and door request switch are integrated into front door outside handle assembly. 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. Refer to "FRONT DOOR OUTSIDE HANDLE ASSEMBLY (OUTSIDE KEY ANTENNA) ".
17	Front door switch (Driver side)	Door switch detects door open/close condition and then transmits ON/OFF signal to BCM. Refer to "FRONT DOOR SWITCH ".
18	Front door lock assembly (Driver side)	Door key cylinder switch is integrated into front door lock assembly (driver side). Door key cylinder switch detects door LOCK/UNLOCK operation using mechanical key, and then transmits the operation signal to BCM. Refer to "FRONT DOOR LOCK ASSEMBLY (DRIVER SIDE) ".
19	Sliding door switch LH	Door switch detects door open/close condition and then transmits ON/OFF signal to BCM. Refer to "SLIDING DOOR SWITCH ".
20	Back door opener switch assembly	Back door opener switch and back door request switch are integrated into back door opener 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. Refer to "BACK DOOR OPENER SWITCH ".
21	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. Refer to "BACK DOOR LOCK ASSEMBLY (WITHOUT AUTOMATIC BACK DOOR SYSTEM) " or "BACK DOOR LOCK ASSEMBLY (WITH AUTOMATIC BACK DOOR SYSTEM) ".
22	Outside key antenna (rear bumper)	Outside key antenna detects whether or not Intelligent Key is within the outside key antenna detection area. Refer to "DOOR LOCK SYSTEM: COMPONENT PARTS LOCATION " for detailed installation location.
23	Sliding door switch RH	Door switch detects door open/close condition and then transmits ON/OFF signal to BCM. Refer to "SLIDING DOOR SWITCH ".
