System DescriptionEIS002TM
IVIS (Infiniti Vehicle Immobilizer System-NATS) has the following immobilizer functions:
Since only IVIS (NATS) ignition keys, whose IDs have been registered into the ECM and BCM, allow the
engine to run, operation of a stolen vehicle without an IVIS (NATS) registered key is prevented by IVIS
(NATS).
IVIS (NATS) will immobilize the engine if someone tries to start it without the registered key of IVIS
(NATS).
All of the originally supplied ignition key IDs have been IVIS (NATS) registered.
If requested by the vehicle owner, a maximum of five key IDs can be registered into the IVIS (NATS) com-
ponents.
The security indicator blinks when the ignition switch is in OFF or ACC position. IVIS (NATS) warns out-
siders that the vehicle is equipped with the anti-theft system.
When IVIS (NATS) detects a malfunction, the security indicator lamp lights up while ignition key is in the
ON position.
IVIS (NATS) trouble diagnoses, system initialization and additional registration of other IVIS (NATS) igni-
tion 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 is automatically
IVIS (NATS) registered. Then, if necessary, additional registration of other IVIS (NATS) ignition key IDs
can be carried out.
Regarding the procedures of IVIS (NATS) initialization and IVIS (NATS) ignition key ID registration, refer
to CONSULT-II Operation Manual NATS-IVIS/NVIS.
When servicing a malfunction of the IVIS (NATS) (indicated by lighting up of Security Indicator
Lamp) or registering another IVIS (NATS) ignition key ID, it may be necessary to re-register origi-
nal key identification. Therefore, be sure to receive ALL KEYS from vehicle owner.
System CompositionEIS0 02 T N
The immobilizer function of the IVIS (NATS) consists of the following:
NATS ignition key
NATS antenna amp. located in the ignition key cylinder
Body control module (BCM)
Engine control module (ECM)
Security indicator
NOTE:
The communication between ECM and BCM uses the CAN communication system.
