VEHICLE SECURITY (THEFT WARNING) SYSTEM
Revision: 2006 January2006 M35/M45
Diagnostic Procedure 3NIS00207
FRONT DOOR KEY CYLINDER SWITCH CHECK
1. CHECK KEY CYLINDER SWITCH OPERATION
Check if door key cylinder switch using mechanical key.
Do doors lock / unlock when using the mechanical key?
YES >> Front door key cylinder switch operation is OK.
NO >> Check door key cylinder switch circuit. Refer to BL-42, "
Door Key Cylinder Switch Check" .
Diagnostic Procedure 4NIS00208
VEHICLE SECURITY HORN ALARM CHECK
First perform the “SELF-DIAG RESULTS” of “BCM” with CONSULT-II, then perform the trouble diagno-
sis of malfunction system indicated in “SELF-DIAG RESULTS” of “BCM”. Refer to BCS-15, "
CAN Com-
munication Inspection Using CONSULT-II (Self-Diagnosis)".
1. CHECK HORN OPERATION
Check if horn sounds with horn switch.
Does horn operate?
Yes >> GO TO 2.
No >> Check horn circuit. Refer to WW-53, "
HORN" .
2. CHECK IPDM E/R INPUT SIGNAL
Check voltage between IPDM E/R connector and ground.
OK or NG
OK >> Replace IPDM E/R.
NG >> GO TO 3.
3. CHECK HORN RELAY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R and horn relay connector.
3. Check continuity between IPDM E/R connector and horn relay connector.
OK or NG
OK >> Check harness connection.
NG >> Repair or replace harness.

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.
