System DiagramINFOID:0000000003814902
System DescriptionINFOID:0000000003814903
The engine start function of Intelligent Key system is a system that makes it possible to start and stop the
engine without removing the key. It verifies the electronic ID using two-way communication when pressing
the push-button ignition switch while carrying the Intelligent Key, which operates based on the results of
electronic ID verification for Intelligent Key using two-way communication between the Intelligent Key and
the vehicle.
NOTE:
The driver should carry the Intelligent Key at all times.
Intelligent Key has 2 IDs [for Intelligent Key and for NVIS (NATS)]. It can perform the door lock/unlock oper-
ation and the push-button ignition switch operation when the registered Intelligent Key is carried.
When the Intelligent Key battery is discharged, it can be used as emergency back-up by inserting the Intelli-
gent Key to the key slot. At that time, perform the NVIS (NATS) ID verification. If it is used when the Intelli-
gent Key is carried, perform the Intelligent Key ID verification.
If the ID is successfully verified, and when push-button ignition switch is pressed, steering lock will be
released and starting the engine will be possible.
If the door lock/unlock operation is performed when the Intelligent Key battery is discharged, all doors lock/
unlock can be performed by operating the driver door key cylinder using the mechanical key set in the Intel-
ligent Key.
Up to 4 Intelligent Keys can be registered (Including the standard Intelligent Key) on request from the owner.
NOTE:
Refer to SEC-9, "
System Description" for any functions other than engine start function of Intelligent Key
system.
PRECAUTIONS FOR INTELLIGENT KEY SYSTEM
In the Intelligent Key system, the transponder [the chip for NVIS (NATS) ID verification] is integrated
into the Intelligent Key. (For the conventional models, it is integrated into the mechanical key.) There-
fore, the mechanical key cannot perform the ID verification, and thus it cannot start the engine.
Instead, the NVIS (NATS) ID verification can be performed by inserting the Intelligent Key into the key
slot, and then it can start the engine.
OPERATION WHEN INTELLIGENT KEY IS CARRIED
1. When the push-button ignition switch is pressed, the BCM signals the inside key antenna and transmits
the request signal to the Intelligent Key.
2. The Intelligent Key receives the request signal and transmits the Intelligent Key ID signal to the BCM via
the remote keyless entry receiver.
3. The BCM receives the Intelligent Key ID signal and verifies it with the registered ID.
