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-8, "
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. Transmission range switch Transmission range switch detects the CVT
shift selector lever position.
4. IPDM E/R Starter control relay is used for the engine
starting function. Starter control relay is con-
trolled by IPDM E/R while communicating
with BCM. IPDM E/R se
nds the starter control
relay statu signal to BCM.
5. 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-77, "
BODY CONTROL SYS-
TEM : Component Parts Location" for de-
tailed installation location.
6. Clutch interlock switch Clutch interlock switch detects that clutch
pedal is depressed, and then transmits ON/
OFF signal to the BCM.
7. Stop lamp switch Stop lamp switch detects that brake pedal is
depressed, and then transmits ON/OFF sig-
nal to the BCM.
8. 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
PWC-6, "
Component Parts Loca-
tion".
9. 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.

• 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 : BCMINFOID:0000000012430444
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 t he 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 : ECMINFOID:0000000012430445
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.
NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS : IPDM E/RINFOID:0000000012430446
IPDM E/R has the starter control relay inside. Starter control relay is used for the engine starting function.
IPDM E/R controls this relay while communicating with BCM.
NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS : Combination MeterINFOID:0000000012430447
Combination meter transmits the vehicle speed signal to BCM via CAN communication.
BCM also receives the vehicle speed signal from ABS ac tuator and electric unit (control unit) via CAN commu-
nication. BCM compares both signals to detect the vehicle speed.
10. Front door switch LH Door switch detects door open/close condi-
tion and then transmits ON/OFF signal to
BCM.
11. Rear door switch LH Door switch detects door open/close condi-
tion and then transmits ON/OFF signal to
BCM.
12. Ignition switch Input ignition switch ON/OFF condition to
BCM.
13. NATS antenna amp. ID verification is performed between the BCM
and the transponder integrated into the key
via the NATS antenna amp.
14. Remote keyless entry receiver Remote keyless entry receiver receives but-
ton operation signal and key ID signal then
transmits them to the BCM.
No.

SYSTEM DESCRIPTION
NATS (Nissan Anti-Theft System) has the following immobilizer functions:
• Engine immobilizer shows high anti-theft performance to prevent engine from starting by anyone other than
the owner.
• Only a key with key ID registered in BCM and ECM can start engine, and shows high anti-theft performance to prevent key from being copied or stolen.
• Security indicator always flashes with mec hanical key removed condition (key switch: OFF)
• Therefore, NATS warns outsider s that the vehicle is equipped with the anti-theft system.
• If system detects malfunction, security indicator illuminates when ignition switch is turned to ON position.
• If the owner requires, ignition key ID or mechanical key ID can be registered for up to 5 keys.
• During trouble diagnosis or when the following parts have been replaced, and if ignition key is added, regis-
tration
*1 is required:
*1: All keys kept by the owner of the vehi cle should be registered with mechanical key.
-ECM
-BCM
- Ignition key
- Remote keyless entry receiver
• NATS trouble diagnosis, system initialization and additional registration of other mechanical key IDs must be
carried out using CONSULT.
• When NATS initialization has been completed, the ID of the inserted mechanical key or mechanical key IDs can be carried out.
• Possible symptom of NATS malfunction is “Engine cannot start”. Identify the possible causes according to
“Work Flow”, Refer to SEC-139, "
Work Flow".
• If ECM other than Genuine NISSAN is installed, the engine cannot be started. For ECM replacement proce- dure, refer to EC-477, "
Removal and Installation".
