Function

1.

Combination meter

Combination meter transmits the vehicle
speed signal to BCM via CAN communica-
tion.
BCM also receives the vehicle speed signal
from ABS actuator and electric unit (control
unit) via CAN communication. BCM com-
pares both signals to detect the vehicle
speed.
Security indicator lamp is located on combi-
nation 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

MWI-6, "METER SYSTEM : Combi-

nation Meter"

.

2.

Inside key antenna (instrument center)

Inside key antenna (instrument center) de-
tects whether Intelligent Key is inside the ve-
hicle or not, and then transmits the signal to
the BCM.

3.

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 the combination meter via CAN commu-
nication. BCM compares both signals to de-
tect the vehicle speed.
Refer to

BRC-8, "ABS Actuator and Electric

Unit (Control Unit)"

for detailed installation lo-

cation.

4.

Intelligent Key warning buzzer

Intelligent Key warning buzzer warns the us-
er, who is outside the vehicle, of operation
confirmation according to Intelligent Key op-
eration and door request switch operation, or
of an inappropriate operation.

5.

Hood switch

Hood switch detects that brake hood is open
or closed, and then transmits that signal to
the IPDM E/R

6.

Transmission range switch

Transmission range switch detects the CVT
shift selector lever position.

7.

IPDM E/R

Starter control relay is 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 sta-
tus signal to BCM.

8.

BCM

BCM controls INTELLIGENT KEY SYSTEM
(ENGINE START FUNCTION), NISSAN VE-
HICLE 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

BCS-6, "BODY CONTROL SYSTEM

: Component Parts Location"

for detailed in-

stallation location.

9.

Clutch interlock switch

Clutch interlock switch detects that clutch
pedal is depressed, and then transmits ON/
OFF signal to the BCM

10.

Stop lamp switch

Stop lamp switch detects that brake pedal is
depressed, and then transmits ON/OFF sig-
nal to the BCM

11.

Main power window and door lock/unlock 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

PWC-7, "Power Window Main

Switch"

.

12.

CVT shift selector (park position switch)

Park position switch is integrated into the
CVT shift selector and detects that the selec-
tor lever is in the P (park) position, then trans-
mits ON/OFF signal to the BCM and IPDM E/
R.

No.

CVT Shift Selector (Park Position Switch)

INFOID:0000000009520883

Park position switch detects that CVT shift selector is in the P (Park) position and then transmits the signal to

BCM and IPDM E/R.

BCM confirms the CVT shift selector position with the following 5 signals:

• P (Park) position signal from CVT shift selector (park position switch)

• P/N position signal from TCM

• P (Park) 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 CVT shift selector position with the following 3 signals:

• P (Park) position signal from CVT shift selector (park position switch)

• P/N position signal from TCM

• P/N position signal from BCM (CAN)

BCM

INFOID:0000000009520884

BCM controls INTELLIGENT KEY SYSTEM (ENGINE START FUNCTION), NISSAN VEHICLE IMMOBI-

LIZER SYSTEM-NATS (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 power supply position is turned ON, BCM performs ID verification between BCM and ECM. If

the ID verification result is OK, ECM can start engine.

ECM

INFOID:0000000009520885

ECM controls the engine.

13.

Front door switch LH

Door switch detects door open/close condi-
tion and then transmits ON/OFF signal to
BCM.

14.

Rear door switch LH

Door switch detects door open/close condi-
tion and then transmits ON/OFF signal to
BCM.

15.

Inside key antenna (trunk room)

Inside key antenna (trunk room) detects
whether Intelligent Key is inside the vehicle or
not, and then transmits the signal to the BCM.
Refer to

SEC-10, "Inside Key Antenna"

.

16.

Inside key antenna (console)

Inside key antenna (console) detects whether

inside which detects that push-button ignition
switch is pressed, and then transmits ON/
OFF signal to BCM. BCM changes the igni-
tion 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.

18.

NATS antenna amp.

ID verification is performed between the BCM
and the transponder integrated into the Intel-
ligent Key via the NATS antenna amp.

19.
