VEHICLE SECURITY (THEFT WARNING) SYSTEM
Revision: 2006 January2006 M35/M45
VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by
opening a door
opening the trunk
opening the hood
detection of battery disconnect and connect.
The vehicle security system will be triggered once the system is in armed phase,
when BCM receives a ground signal at terminals 12 (passenger side door), 13 (rear RH door), 57 (trunk), 62
(driver side door), 63 (rear LH door), or receives a signal from the IPDM E/R (hood switch).
When the vehicle security system is triggered,
ground is supplied intermittently to both headlamp relay and horn relay.
When headlamp relay and horn relay are energized, then power is supplied to headlamps (LH and RH) and
horns (HIGH and LOW).
The headlamps flash and the horn sounds intermittently.
The alarm automatically turns off after 50 seconds, but will reactivate if the vehicle is tampered with again.
VEHICLE SECURITY SYSTEM DEACTIVATION
To deactivate the vehicle security system, a door or the trunk must be unlocked with the key, Intelligent Key.
When the key is used to unlock a door, BCM terminal 22 receives signal
from the power window main switch (door lock and unlock switch) terminal 14.
When the BCM receives either one of these signals or unlock signal from key cylinder switch or Intelligent Key,
the vehicle security system is deactivated. (Disarmed phase)
PANIC ALARM OPERATION
Intelligent Key system may or may not operate vehicle security system (horn and headlamps) as required.
When the Intelligent Key system is triggered, ground is supplied intermittently to both headlamp relay and horn
relay.
When headlamp relay and horn relay are energized, then power is supplied to headlamps (LH and RH) and
horns (HIGH and LOW).
The headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off after 25 seconds or when BCM receives any signal from Intelligent Key.
CAN Communication System DescriptionNIS001ZV
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

IVIS (INFINITI VEHICLE IMMOBILIZER SYSTEM-NATS)
Revision: 2006 January2006 M35/M45
System DescriptionNIS0020D
DESCRIPTION
The IVIS (NATS) is an anti-theft system by registering an Intelligent Key ID in to the vehicle and prevents
the engine being started by an unregistered Intelligent Key. It has a higher protection against auto thefts
that duplicates mechanical key.
It performs the ID verification when starting the engine in the same way as the Intelligent Key system. But,
it performs the IVIS (NATS) ID verification when inserting the Intelligent Key and performs the Intelligent
Key ID verification when carrying the Intelligent Key.
The Intelligent Key system of FUGA (Y50) is not the same as the conventional models. The mechanical
key integrated in the Intelligent Key cannot start the engine. When the Intelligent Key battery is dis-
charged, the IVIS (NATS) ID verification memorized to the transponder integrated with Intelligent Key is
performed by inserting the Intelligent Key into the key slot. If the verification results are OK, the engine
start operation can be performed by the push-button ignition switch operation.
Locate the security indicator and apply the anti-theft system equipment sticker, forewarn that the IVIS
(NATS) is onboard with the model.
The security indicator always blinks when the Intelligent Key is removed from the key slot and when the
power supply position is in LOCK position.
Intelligent Key can be registered up to 4 keys (Including the standard ignition key) on request from the
owner.
The specified registration is required when replacing ECM, BCM or Intelligent Key. The registrations pro-
cedure for IVIS (NATS) and registration procedure for Intelligent Key when installing the Intelligent Key
unit, refer to CONSULT-II Operation Manual NATS-IVIS/NVIS.
Possible symptom of IVIS (NATS) malfunction is “Engine cannot start”. In FUGA (Y50), the engine can be
started with the Intelligent Key system and IVIS (NATS). Identify the possible causes according to “Work
Flow”, Refer to BL-272, "
Work Flow" .
If ECM other than Genuine NISSAN is installed, the engine cannot be started. For ECM replacement pro-
cedure, refer to BL-252, "
ECM Re-Communicating Function" .
PRECAUTIONS FOR KEY REGISTRATION
The key registration is a procedure that erases the current IVIS (NATS) ID once, and then re register a
new ID operation. Therefore the registered Intelligent Key is necessary for this procedure. Before starting
the registration operation collect all registered Intelligent Key from the customer
When registering the Intelligent Key, 2 registration procedures [IVIS (NATS) ID registration and Intelligent
Key ID registration] should be performed. The IVIS (NATS) ID registration is the procedure that registers
the ID stored into the transponder (integrated into Intelligent Key) to the BCM. The Intelligent Key ID reg-
istration is the procedure that registers the ID to the Intelligent Key unit. Each registration procedure
should be done separated.
When performing the Intelligent Key system registration only, the engine cannot be started by inserting the
key into the key slot. When performing the IVIS (NATS) registration only, the engine cannot be started by
the operation when carrying the key. The registrations of both systems should be performed.
SECURITY INDICATOR
Warn the outside that the vehicle is the model with IVIS (NATS).
The security indicator always blinks when the Intelligent Key is removed from the key slot and when the
ignition switch is in LOCK position.
NOTE:
Because security indicator is highly efficient, the battery is barely affected.
