< 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
