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.
Refer to

MWI-5, "METER SYSTEM : Compo-

nent Parts Location"

.

2.

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-7, "Component Parts Location"

for detailed installation location.

3.

Hood switch

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

4.

Transmission range switch

Transmission range switch detects the CVT
shift selector lever position.

5.

IPDM E/R

Starter control relay is 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.

6.

BCM

BCM controls NISSAN VEHICLE IMMOBI-
LIZER SYSTEM-NATS [NVIS (NATS)] and
VEHICLE SECURITY SYSTEM.
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-73, "BODY CONTROL SYS-

TEM : Component Parts Location"

for de-

tailed installation location.

7.

Clutch interlock switch

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

8.

Stop lamp switch

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

9.

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.

PWC-6, "Component Parts Loca-

tion"

NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS : CVT Shift Selector (Park Position
Switch)

INFOID:0000000009698610

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)

NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS : BCM

INFOID:0000000009698611

BCM controls ENGINE START FUNCTION, NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS (NATS), and

VEHICLE SECURITY SYSTEM.

BCM performs the ID verification between BCM and key. If the ID verification result is OK, ignition switch oper-

ation 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.

NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS : ECM

INFOID:0000000009698612

ECM controls the engine.

When power supply position is turned ON, BCM starts communication with ECM and performs the ID verifica-

tion between BCM and ECM.

If the verification result is OK, the engine can start. If the verification result is invalid, the engine can not start.

10.

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.

11.

Front door switch LH

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

12.

Rear door switch LH

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

13.

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.

14.

NATS antenna amp.

ID verification is performed between the BCM
and the transponder integrated into the key
via the NATS antenna amp.

15.

Remote keyless entry receiver

Remote keyless entry receiver receives but-
ton operation signal and key ID signal then
transmits them to the BCM.

No.

COMPONENT PARTS

NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS : IPDM E/R

INFOID:0000000009698613

IPDM E/R has the starter relay and starter control relay inside. Starter relay and starter control relay are used

for the engine starting function. IPDM E/R controls these relays while communicating with BCM.

NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS : Combination Meter
