< FUNCTION DIAGNOSIS >

[WITHOUT INTELLIGENT KEY SYSTEM]

NVIS (NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS)

• Possible symptom of NATS malfunction is “Engine cannot start”. Identify the possible causes according to

“Work Flow”, Refer to 

SEC-120, "Work Flow"

.

• If ECM other than Genuine NISSAN is installed, the engine cannot be started. For ECM replacement proce-

dure, refer to 

SEC-124, "ECM RE-COMMUNICATING FUNCTION : Description"

.

PRECAUTIONS FOR KEY REGISTRATION

• The key registration is a procedure that erases the current NATS ID once, and then re-registers a new ID.

Therefore the registered key is necessary for this procedure. Before starting the registration operation collect

all registered Keys from the customer.

• The NATS ID registration is the procedure that registers the ID stored into the transponder (integrated in

mechanical key) to BCM.

The key ID registration is the procedure that registers the ID to the BCM.

• When performing the key system registration only, the engine cannot be started by inserting the key into the

key cylinder. When performing the NATS registration only, the engine cannot be started by using the ignition

key.

SECURITY INDICATOR

• Always flashes with ignition key in the OFF position. 

MAINTENANCE INFORMATION

CAUTION:

It is necessary to perform NATS ID registration when replacing any of the following part.

If it's not (or fail to do so), the electrical system may not operate properly.

• BCM

• ECM

• IPDM E/R

• Ignition key

• NATS antenna amp.

• Combination meter

System Description

INFOID:0000000005259042

DESCRIPTION

The security system provides an audible and visual alarm when an unauthorized access to the vehicle is

detected while the system is in armed phase.

The security system consist of the BCM managing the audible alarm (horn) and the visual alarm (headlamps).

OPERATION FLOW

Disarmed Phase

When the vehicle is being driven or when doors are open, the theft warning system is set in the disarmed

phase on the assumption that the owner is inside or near the vehicle.

Pre-Armed Phase And Armed Phase

The vehicle security system turns into the pre-armed phase when ignition switch is in OFF position, all doors

including glass hatch are closed and locked (using keyfob, doorlock/unlock switch, driver key cylinder or auto

relock function). The system automatically shifts into the armed phase.

Condition of Activating The System

When the following condition is performed in armed phase, the system sounds the horns and flashes the

headlamps for about 50 seconds.

• Any door is opened.
