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

• 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.

dure, refer to

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
• 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.
