Component
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.

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
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
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
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
16.
Inside key antenna (console)
Inside key antenna (console) detects whether
Intelligent Key is inside the vehicle or not, and
then transmits the signal to the BCM.
Refer to
17.
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 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.
