IVIS (INFINITI VEHICLE IMMOBILIZER SYSTEM-NATS)
System Description
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 discharged, 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 on-board 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 procedure for IVIS (NATS) and registration procedure for Intelligent Key when installing the Intelligent Key unit, refer to CONSULT-III 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 Work Flow.
- If ECM other than Genuine NISSAN is installed, the engine cannot be started. For ECM replacement procedure, refer to Programming and Relearning.
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 registration 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.
