SYSTEM DESCRIPTION

NATS (Nissan Anti-Theft System) has the following immobilizer functions:
• Engine immobilizer shows high anti-theft performance to prevent engine start by 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 mechanical key removed condition (key switch: OFF).
• Therefore, NATS warns outsiders that the vehicle is equipped with the anti-theft system. Refer to

SEC-165,

"System Description"

.

• If system detects malfunction, security indicator illuminate when ignition switch is turned to ON position.
• If the owner requires, ignition 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* is required.

*1

: All keys kept by the owner of the vehicle should be registered with ignition key.

- ECM
- BCM
- Ignition key
- ABS actuator control unit
- EPS sontrol unit
- IPDM E/R

• NATS trouble diagnosis, system initialization and additional registration of other Ignition key IDs must be car-

ried out using CONSULT-III hardware and SECURITY CARD.

PRECAUTIONS FOR KEY REGISTRATION

• The key registration is a procedure that erases the current NATS ID once, and then re-registers a new ID.

Therefore the registered ignition key is necessary for this procedure. Before starting the registration opera-
tion collect all registered ignition keys from the customer

• The NATS ID registration is the procedure that registers the ID stored into the transponder (integrated in

ignition key) to BCM.

• Security indicator blinks when the ignition switch is in “OFF” or “ACC” position.
• When NATS detects trouble, the security indicator lamp lights up while ignition key is in the “ON” position.
