NISSAN VEHICLE IMMOBILIZER SY STEM-NATS : Stop Lamp SwitchINFOID:0000000012430452
Stop lamp switch detects that brake pedal is depressed, and then transmits the signal to BCM.
NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS : Transmission Range Switch
INFOID:0000000012430453
Transmission range switch is integrated in CVT assembly, and detects the CVT shift selector position.
TCM receives the transmission range switch signal and then transmits the P/N position 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 sele ctor 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)

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".
