IVIS (INFINITI VEHICLE IMMOBILIZER SYSTEM-NATS)
Revision: 2007 April2007 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-269, "
Work Flow" .

If ECM other than Genuine NISSAN is installed, the engine cannot be started. For ECM replacement pro-
cedure, refer to BL-248, "
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.

CHECKING BRAKE FLUID LEVEL

Make sure that a brake fluid level in reservoir tank is within the
standard (between MAX and MIN lines).

Visually check around reservoir tank for fluid leakage.

If the level is excessively low, check brake system for leakage.

Release parking brake pedal and see if brake warning lamp
goes off. If not, check brake system for fluid leakage.
Checking Brake LineNFS000RW
CAUTION:
If leakage occurs around joints, retighten or, if necessary, replace damaged parts.
1. Check brake line (tubes and hoses) for cracks, deterioration or other damage. Replace any damaged
parts.
2. Check for oil leakage by fully depressing brake pedal while
engine is running.
Drain and RefillNFS000RX
CAUTION:

Refill with new brake fluid “DOT 3”.

Never reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.

Before working, disconnect connectors of ABS actuator and electric unit (control unit) or battery
cable from the negative terminal.
1. Connect a vinyl tube to bleed valve.
2. Depress brake pedal, loosen bleed valve, and gradually remove
brake fluid.
