System Description

EIS00129

IVIS (Infinity Vehicle Immobilizer System – NATS) has the following immobilizer functions:

Since only IVIS (NATS) electronic keys, whose ID numbers. have been registered into the ECM and NATS
IMMU of IVIS (NATS), allow the engine to run, operation of a stolen vehicle without a IVIS (NATS) regis-
tered electronic key is pre-vented by IVIS (NATS).
That is to say, IVIS (NATS) will immobilize the engine if someone tries to start it without the registered
electronic key of IVIS (NATS).

All of the originally supplied electronic key IDs (except for card key and emergency key) have been IVIS
(NATS) registered. If requested by the vehicle owner, a maximum of four key IDs can be registered into
the IVIS (NATS) components.

The security indicator blinks when the ignition switch is in “OFF” or “ACC” position. Therefore, IVIS
(NATS) warns outsiders that the vehicle is equipped with the anti-theft system.

When IVIS (NATS) detects any malfunctions, the security indicator lamp lights up while electronic key is in
the “ON” position.

IVIS (NATS) trouble diagnoses, system initialization and additional registration of other IVIS (NATS) elec-
tronic 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 electronic key is automatically
IVIS (NATS) registered. Then, if necessary, additional registration of other IVIS (NATS) electronic key IDs
can be carried out.
Regarding the procedures of IVIS (NATS) initialization and IVIS (NATS) electronic key ID registration,
refer to CONSULT-II operation manual, IVIS/NVIS.
