System DescriptionNIS0003C
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, 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-III hardware and CONSULT-III NVIS (NATS) soft-
ware.
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-III 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.

NVIS (NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS)
Revision: 2006 November2007 350Z
System CompositionNIS0003D
The immobilizer function of the NVIS (NATS) consists of the following:

NATS ignition key

NATS antenna amp. located in the ignition key cylinder

BCM

Engine control module (ECM)

Security indicator
NOTE:
The communication between ECM and BCM uses the CAN communication system.
ECM Re-communicating FunctionNIS0003E
Performing following procedure can automatically perform re-communication of ECM and BCM, but only
when the ECM has been replaced with a new one (*1).
*1: New one means a virgin ECM which has never been energized on-board.
(In this step, initialization procedure by CONSULT-III is not necessary)
NOTE:

When registering new Key IDs or replacing the ECM other than brand new, refer to CONSULT-III
Operation Manual NATS-IVIS/NVIS.

If multiple keys are attached to the key holder, separate them before work.

Distinguish keys with unregistered key ID from those with registered ID.
1. Install ECM.
2. Using a registered key (*2), turn ignition switch to “ON”.
*2: To perform this step, use the key (except for card plate key) that has been used before performing
ECM replacement.
3. Maintain ignition switch in “ON” position for at least 5 seconds.
4. Turn ignition switch to “OFF”.
5. Start engine.
If engine can be started, procedure is completed.
If engine cannot be started, refer to CONSULT-III Operation Manual NATS-IVIS/NVIS and initialize control
unit.
