NOTE:
If customer reports a “NO START” condition, request ALL KEYS to be brought to an NISSAN dealer in
case of a NVIS (NATS) malfunction.

System Description

NIS0019P

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

DESCRIPTION

●

Engine immobilizer shows high anti-theft performance to prevent engine start by other than the owner
(registered key: ignition key, mechanical key and Intelligent Key).

●

Only a key with key ID registered in BCM and ECM can start engine, and shows high anti-theft perfor-
mance to prevent key from being copied or stolen.

●

In the vehicle without Intelligent Key system, security indicator always flashes with other than ignition
switch ON or START position.

●

In the vehicle with Intelligent Key system, security indicator always flashes with mechanical key removed
condition (key switch OFF) and ignition knob released condition on LOCK position (ignition knob switch
OFF).

PIIB8713E

NVIS (NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS)

BL-237

Revision: 2006 August

2006 Murano

●

Therefore, NVIS (NATS) warns outsiders that the vehicle is equipped with the anti-theft system.

●

If system detects malfunction, it turns on security indicator in ignition switch ON position.

●

If the owner requires, ignition key ID or mechanical key ID can be registered for up to 5 keys.

●

During trouble diagnosis or when the following parts have been replaced, and if ignition key or mechanical
key is added, registration* is required.
*: All keys kept by the owner of the vehicle should be registered with ignition key or mechanical key.

–

ECM

–

BCM

–

Ignition key (models without Intelligent Key system)

–

Mechanical key (models with Intelligent Key system)

●

NVIS (NATS) trouble diagnoses, system initialization and additional registration of other NVIS (NATS)
ignition key or mechanical 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 igni-
tion key or mechanical key or mechanical key IDs can be carried out.
Regarding the procedures of NVIS (NATS) initialization and ignition key or mechanical key ID registration,
refer to CONSULT-II operation manual, NATS-IVIS/NVIS.

SECURITY INDICATOR

●

Warns that the vehicle has NVIS (NATS).

●

In the vehicle without Intelligent Key system, security indicator always flashes with other than ignition
switch ON or START position. In the vehicle with Intelligent Key system, security indicator always flashes
with mechanical key removed condition (key switch OFF) and ignition knob released condition on LOCK
position (ignition knob switch OFF).

NOTE:
Because security indicator is highly efficient, the battery is barely affected.

Condition of Security Indicator

WITHOUT INTELLIGENT KEY SYSTEM

WITH INTELLIGENT KEY SYSTEM

●

In ignition knob operation with Intelligent Key, it always turns on with pushing ignition knob, and always
flashes with ignition knob released (ignition knob switch OFF) condition on ignition knob “LOCK” position.

●

In ignition knob operation with mechanical key, it turns off on the condition that mechanical key is inserted
in key cylinder, and always flashes with ignition knob released (ignition knob switch OFF) condition on
mechanical key removed condition.

System Composition

NIS0019Q

The immobilizer function of the NVIS (NATS) consists of the following:

●

NATS ignition key (without Intelligent Key system)

●

Mechanical key (with Intelligent Key system)

●

NATS antenna amp. located in the ignition key cylinder

●

Body control module (BCM)

●

Engine control module (ECM)

●

Security indicator

●

Steering lock unit (with Intelligent Key system)

●

Intelligent Key unit (with Intelligent Key system)

NOTE:
The communication between ECM, BCM and/or Intelligent Key unit uses the CAN communication sys-
tem.

ECM Re-communicating Function

NIS0019R

Performing following procedure can automatically perform re-communication of ECM and BCM or Intelligent
Key unit, 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-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 (*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.

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.
