No.	Component	Function
1.	Combination meter	Combination meter transmits the Nissan Murano 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 Nissan Murano vehicle speed. Security indicator lamp is located on combination meter. Security indicator lamp blinks when push-button ignition switch is in anything else other than ON to warn that NISSAN Nissan Murano Vehicle IMMOBILIZER SYSTEM-NATS [NVIS (NATS)] is on board. Refer to Component Parts Location for detailed component location.
2.	Transmission range switch	The transmission range switch detects the selector lever position. Refer to Transmission Range Switch for detailed component location.
3.	ECM (Engine Control Module)	ECM detects the "P" or "N" position from transmission range switch signal. Refer to ECM for detailed component location.
4.	IPDM E/R (Intelligent Power Distribution Module Engine Room)	IPDM E/R detects push-button ignition switch (push switch) status and transmits push-button ignition switch status signal (CAN) to BCM. Refer to Component Parts Location for detailed component location.
5.	BCM (Body Control Module)	BCM controls INTELLIGENT KEY SYSTEM (ENGINE START FUNCTION), NISSAN Nissan Murano 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, push-button ignition switch operation is available. Then, when the push-button ignition switch is placed ON, BCM performs ID verification between BCM and ECM. If the ID verification result is OK, ECM can start engine. Refer to Component Parts Location for detailed component location.
6.	Main power window and door lock/unlock switch	Door lock and unlock switch is integrated into the main power window and door lock/unlock switch. Door lock and unlock switch transmits door lock/unlock operation signal to BCM. Refer to Main Power Window and Door Lock/Unlock Switch for detailed component location.
7.	Inside key antenna (console)	Inside key antenna (console) detects whether Intelligent Key is inside the Nissan Murano vehicle or not, and then transmits the signal to the BCM. Refer to Inside Key Antenna (console) for detailed component location.
8.	Front door switch LH	Front door switch LH transmits door open/closed signal to the BCM. Refer to Front Door Switch for detailed component location.
9.	Inside key antenna (luggage room)	Inside key antenna (luggage room) detects whether Intelligent Key is inside the Nissan Murano vehicle or not, and then transmits the signal to the BCM. Refer to Inside Key Antenna (luggage room) for detailed component location.
10.	Rear door switch LH	Rear door switch LH transmits door open/closed signal to the BCM. Refer to Rear Door Switch for detailed component location.
11.	Rear door switch RH	Rear door switch RH transmits door open/closed signal to the BCM. Refer to Rear Door Switch for detailed component location.
12.	Front door switch RH	Door switch detects door open/close condition and then transmits ON/OFF signal to BCM. Refer to Front Door Switch for detailed component location.
13.	Power window and door lock/unlock switch RH	Door lock and unlock switch transmits door lock/unlock operation signal to BCM. Refer to Power Window and Door Lock/Unlock Switch RH for detailed component location.
14.	Remote keyless entry receiver	Remote keyless entry receiver receives button operation signal and key ID signal of Intelligent Key and then transmits them to BCM. Refer to Remote Keyless Entry Receiver for detailed component location.
15.	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 push-button ignition switch position with the operation of push-button ignition switch. BCM maintains the push-button ignition switch position status while push-button ignition switch is not operated. Refer to Push-button Ignition Switch for detailed component location.
16.	NATS antenna amp.	Refer to NATS Antenna Amp..
17.	Dongle unit (if equipped)	BCM performs ID verification between BCM and dongle unit. When verification result is OK, BCM permits cranking.
18.	Hood switch	Refer to Hood Switch.
19.	Horns (low/high)	IPDM E/R energizes the horns when the security system is activated.
20.	Stop lamp switch	When the stop lamp switch supplies power to the BCM, the BCM supplies power to the shift lock solenoid. Refer to Stop Lamp Switch for detailed component location.
21	CVT shift selector (detent switch)	This switch provides CVT shift selector position to the BCM. Refer to Component Parts Location for detailed component location.
22.	Automatic back door control module (if equipped)	Refer to Automatic Back Door Control Module for detailed component location.
23.	Back door lock assembly	Back door lock actuator locks/unlocks the back door latch assembly. Refer to Back Door Lock Assembly for detailed component location.

NATS Antenna Amp.

NATS Antenna Amp. is installed behind push-button ignition switch.
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.

Hood Switch

Hood switch is integrated into hood lock assembly LH. It is located under the front of hood.
Hood switch detects that hood is open and then transmits ON/OFF signal to IPDM E/R. IPDM E/R transmits hood switch signal to BCM via CAN communication.
