System Description
AIS002KR
NVIS (Nissan Vehicle Immobilizer System-NATS) has the following immobilizer functions:
●
Since only NVIS (NATS) ignition keys, whose ID Nos. have been registered into the ECM and BCM
(NATS control unit), allow the engine to run, a vehicle operation without a key registered in NVIS (NATS)
is prevented by NVIS (NATS).
That is to say, NVIS (NATS) will immobilize the engine if someone tries to start it without the registered
key of NVIS (NATS).
●
All of the originally supplied ignition key IDs (except for card plate key) have been registered in NVIS
(NATS).
If requested by the vehicle owner, a maximum of five key IDs can be registered into the NVIS (NATS)
components.
●
The security indicator blinks when the ignition switch is in “OFF” or “ACC” position. Therefore, NVIS
(NATS) warns outsiders that the vehicle is equipped with the anti-theft system.
●
When NVIS (NATS) detects trouble, the security indicator lamp lights up while ignition key is in the “ON”
position.
●
NVIS (NATS) trouble diagnoses, system initialization and additional registration of other NVIS (NATS)
ignition key IDs must be carried out using CONSULT-II hardware and CONSULT-II NVIS (NATS) software.
When NVIS (NATS) initialization has been completed, the ID of the inserted ignition key is automatically
registered in NVIS (NATS). Then, if necessary, additional registration of other NVIS (NATS) ignition key
IDs can be carried out.
Regarding the procedures of NVIS (NATS) initialization and NVIS (NATS) ignition key ID registration, refer
to CONSULT-II Operation Manual NATS-IVIS/NVIS.
●
When servicing a malfunction of the NVIS (NATS) (indicated by lighting up of Security Indicator
Lamp) or registering another NVIS (NATS) ignition key ID No., it may be necessary to re-register
original key identification. Therefore, be sure to receive ALL KEYS from vehicle owner.
