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 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) and ignition
knob released condition on LOCK position (ignition knob switch: OFF).
• Therefore, NATS warns outsiders that the vehicle is equipped with the anti-theft system. Refer to
.
• 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* is required.
*1
: All keys kept by the owner of the vehicle 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
