PRECAUTIONS FOR INTELLIGENT KEY SYSTEM
In the Intelligent Key system of model Y50, the transponder (the chip for immobilizer ID verifica-
tion) is integrated into the Intelligent Key. (For the conventional models, it is integrated into the
mechanical key.) Therefore, the mechanical key cannot perform the ID verification, and thus it can-
not start the engine. Instead of it, the immobilizer ID verification can be performed by inserting the
Intelligent Key into the key slot, and then it can start the engine.
When registering the Intelligent Key, 2 registration procedures (immobilizer ID registration and
Intelligent Key ID registration) should be performed. The immobilizer ID registration is the proce-
dure 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 is a different procedure.
When performing the Intelligent Key ID registration only, the engine cannot be started by inserting
the key into the key slot. When performing the engine immobilizer ID registration only, the engine
cannot be started by the operation when carrying the key. The registrations of both systems
should be performed.
Operation DescriptionNIS001Y9
SYSTEM DIAGRAM
OPERATION WHEN INTELLIGENT KEY IS CARRIED
Description
1. When the push-button switch is pressed, the Intelligent Key unit signals the inside key antenna and sends
the request signal to the Intelligent Key.
2. The Intelligent Key receives the request signal and sends the Intelligent Key ID signal to the Intelligent
Key unit via the remote keyless entry receiver.
3. The Intelligent Key receives the Intelligent Key ID signal and verifies it with the registered ID.
4. If the ID is successfully verified, the Intelligent Key unit sends the steering unlock signal to the steering
lock unit. Then, it sends each power supply request signal to PDU (Power Distribution Unit) after unlock-
ing the steering lock.
5. If the Intelligent Key unit judges that the engine start condition is satisfied, it sends the starter request sig-
nal via CAN communication to IPDM E/R and turns the starter motor relay ON.
6. The steering lock unit unlocks the steering lock when receiving the signal. PDU starts the power supply
distribution according to the push-button ignition switch operation when receiving the signal. If it enters the
engine start permission mode, the power supply is supplied from PDU to the starter motor relay and the
cranking is started.
CAUTION:
If a malfunction is detected in the Intelligent Key system, the “KEY” warning lamp in the combina-
tion meter illuminates for 15 seconds. At that time, the engine cannot be started.
7. When Intelligent Key unit received feedback signal from ECM acknowledging the engine has been initi-
ated, the Intelligent Key unit sends a stop signal to IPDM E/R and stops the cranking by turning OFF the

starter motor relay. (If the engine initiating has failed, the cranking will stop automatically within 5 sec-
onds.)
CAUTION:
When the Intelligent Key is carried outside of the vehicle (inside key antenna detection area) with
the power supply in ACC or ON position, even if the engine start condition* is satisfied, the engine
cannot be started.
*: For the engine start condition, refer to BL-130, "
PUSH-BUTTON IGNITION SWITCH OPERATION PROCE-
DURE" .
Operation Range
Engine can be started when Intelligent Key is inside the vehicle. However, sometimes engine might not start
when Intelligent Key is on instrument panel or in glove box.
OPERATION WHEN KEY SLOT IS USED
When the Intelligent Key battery is discharged, it performs the immobilizer ID verification between the inte-
grated transponder and BCM by inserting the Intelligent Key into the key slot, and then the engine can be
started.
For details relating to starting the engine using key slot, refer to BL-248, "
IVIS (INFINITI VEHICLE IMMOBI-
LIZER SYSTEM-NATS)" .
PUSH-BUTTON IGNITION SWITCH OPERATION PROCEDURE
The power supply position changing operation can be performed with the following operation.
NOTE:
When an Intelligent Key is within the detection area of inside key antenna and when it is inserted to the
key slot, it is equivalent to the operations below.
When starting the engine, the Intelligent Key unit monitors the engine start conditions (brake pedal operat-
ing condition, A/T selector lever position, and vehicle speed).
Unless each start condition is fulfilled, the engine will not respond regardless of how many times the
engine switch is pushed. At that time, illumination repeats the position in the order of LOCK
