INTELLIGENT KEY SYSTEM/ENGINE START FUNCTION
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.

< FUNCTION DIAGNOSIS >[INTELLIGENT KEY SYSTEM]
INTELLIGENT KEY SYSTEM/ENGINE START FUNCTION
4. BCM transmits the steering lock unlock signal to steering lock unit and IPDM E/R if the verification results
are OK.
5. IPDM E/R turns the steering lock relay ON and supplies power to the steering lock unit.
6. Release of the steering lock.
7. BCM transmits the power supply stop signal to IPDM E/R when it confirms that the steering lock is in the
unlock condition.
8. IPDM E/R turns the steering lock relay OFF and stops power supply to the steering lock unit.
9. BCM turns ACC relay ON and transmits the ignition power supply ON signal to IPDM E/R.
10. IPDM E/R turns the ignition relay ON and starts the ignition power supply.
11. BCM confirms that the shift position is P or N.
12. BCM transmits the starter request signal via CAN communication to IPDM E/R and turns the starter relay
in IPDM E/R ON if BCM judges that the engine start condition is satisfied.
13. IPDM E/R turns the starter control relay ON when receiving the starter request signal.
14. Battery power is supplied through the starter relay and the starter control relay to operate the starter motor
and to start the cranking.
CAUTION:
If a malfunction is detected in the Intelligent Key system, the “KEY” warning lamp in the combina-
tion meter illuminates. At that time, the engine cannot be started.
15. When BCM receives feedback signal from ECM acknowledging the engine has been initiated, the BCM
transmits 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 seconds.)
CAUTION:
When the Intelligent Key is carried outside of the vehicle (inside key antenna detection area) with
the power supply in the ACC or ON position, even if the engine start condition* is satisfied, the
engine cannot be started.
*: For the engine start condition, refer to “PUSH-BUTTON IGNITION SWITCH OPERATION PROCEDURE”.
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 NVIS (NATS) 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 SEC-14, "
System Description".
BATTERY SAVER SYSTEM
When all the following conditions are met for 60 minutes, the battery saver system will cut off the power supply
to prevent battery discharge.
 The ignition switch is in the ACC position
 All doors are closed
 Selector lever is in the P position
Reset Condition of Battery Saver System
If any of the following conditions are met the battery saver system is released and the steering will change
automatically to the lock position from the OFF position.
 Opening any door
 Operating with request switch on door lock
 Operating with Intelligent Key on door lock
Pressing the push-button ignition switch and ignition switch will change the ignition switch to ACC position
from OFF position.
STEERING LOCK OPERATION
Steering is locked by steering lock unit when ignition switch is in the OFF position, selector lever is in the P
position and any of the following conditions are met.
 Opening door
 Closing door
 Door is locked with request switch
 Door is locked with Intelligent Key

The BCM records the following condition at the moment a particular DTC is detected.
 Vehicle Speed
 Odo/Trip Meter
 Vehicle Condition (BCM detected condition)
IGN Counter
IGN counter indicates the number of times that ignition switch is turned ON after DTC is detected.
 The number is 0 when a malfunction is detected now.
 The number increases like 1 → 2 → 3...38 → 39 after returning to the normal condition whenever ignition
switch OFF → ON.
 The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.
