System Description: Description

IVIS (Infiniti Vehicle Immobilizer System - NATS) has the following immobilizer functions:

• Engine immobilizer shows high anti-theft performance to prevent engine start by other than the owner (registered key: ignition key, mechanical key and Intelligent Key).
• 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.
• In the vehicle without Intelligent Key system, security indicator always flashes with other than ignition switch ON or START position.
• In the vehicle with Intelligent Key system, 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, IVIS (NATS) warns outsiders that the vehicle is equipped with the anti-theft system.
• If system detects malfunction, it turns on security indicator in ignition switch ON position.
• If the owner requires, 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 or mechanical key is added, registration* is required.

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

• ECM
• BCM
• Ignition key (models without Intelligent Key system)
• Mechanical key (models with Intelligent Key system)

• IVIS (NATS) trouble diagnoses, system initialization and additional registration of other IVIS (NATS) ignition key or mechanical key IDs must be carried out using CONSULT-II hardware and CONSULT-II IVIS (NATS) software. When IVIS (NATS) initialization has been completed, the ID of the inserted ignition key or mechanical key or mechanical key IDs can be carried out.

  Regarding the procedures of IVIS (NATS) initialization and ignition key or mechanical key ID registration, refer to CONSULT-II operation manual, NATS-IVIS/NVIS.
