System Description

EIS007QA

NVIS (Nissan Vehicle Immobilizer System-NATS) has the following immobilizer functions:

●

Since only NVIS (NATS) ignition keys, whose IDs have been registered into the ECM and BCM, allow the
engine to run, operation of a stolen vehicle without a NVIS (NATS) registered key is prevented by NVIS
(NATS).
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 have been NVIS (NATS) registered.
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. NVIS (NATS) warns out-
siders that the vehicle is equipped with the anti-theft system.

●

When NVIS (NATS) detects a malfunction, 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
NVIS (NATS) registered. 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, it may be necessary to re-register origi-
nal key identification. Therefore, be sure to receive ALL KEYS from vehicle owner.

System Composition

EIS007QB

The immobilizer function of the NVIS (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.

ECM Re-communicating Function

EIS007QC

The following procedure can automatically perform re-communication of ECM and BCM, but only when the
ECM has been replaced with a new one which has never been energized on-board.
(In this step, initialization procedure by CONSULT-II is not necessary)

NOTE:

●

When registering new key IDs or replacing the ECM other than brand new, refer to CONSULT-II
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.

Install ECM.

Using a registered key (*1), turn ignition switch to ON.
*1: To perform this step, use the key that has been used before performing ECM replacement.

Maintain ignition switch in ON position for at least 5 seconds.

Turn ignition switch to OFF.

Start engine.
If engine can be started, procedure is completed.
If engine cannot be started, refer to CONSULT-II Operation Manual NATS-IVIS/NVIS and initialize control
unit.

CONSULT-II INSPECTION PROCEDURE

CAUTION:

If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carries out CAN communication.

Turn ignition switch OFF.

Insert NVIS (NATS) program card into CONSULT-II.

Connect CONSULT-II and CONSULT-II CONVERTER to data
link connector.

Turn ignition switch ON.

Touch “START”.

Touch "OTHER".

Select “NATS V.5.0”.
If “NATS V5.0” is not indicated, go to

Perform each diagnostic test mode according to each service
procedure.

For further information, see the CONSULT-II Operation Manual
NATS-IVIS/NVIS.

CONSULT-II DIAGNOSTIC TEST MODE FUNCTION

NOTE:

●

When any initialization is performed, all IDs previously registered will be erased and all NATS ignition keys
must be registered again.

●

The engine cannot be started with an unregistered key. In this case, the system will show “DIFFERENCE
OF KEY” or “LOCK MODE” as a self-diagnostic result on the CONSULT-II screen.

●

In rare case, “CHAIN OF ECM-IMMU” might be stored as a self-diagnostic result during key registration
procedure, even if the system is not malfunctioning.
