The settings for the Intelligent Key system functions can be changed using CONSULT-III (WORK SUPPORT).
Refer to BL-101, "
CONSULT-III Application Item".
NOTE:
Once a function setting is changed, it will remain effective even if the battery is disconnected.
INTELLIGENT KEY REGISTRATION
Intelligent Key-ID registration is performed using the CONSULT-III.
CAUTION:
• After a new Intelligent Key-ID is registered, be sure to check the function.
• When registering an additional Intelligent Key-ID, take any Intelligent Keys already registered and
Intelligent Keys for any other vehicles out of the vehicle before starting.
CONSULT-III can be used to check and delete Intelligent Key-IDs.
For further information, see the CONSULT-III Operation Manual NATS.
STEERING LOCK SOLENOID REGISTRATION
Steering Lock Solenoid ID Registration
CAUTION:
• The method for registering a steering lock solenoid ID depends on the status of the steering lock
solenoid and Intelligent Key unit (new or old unit).
• After registration is completed, press ignition switch with an Intelligent Key in the vehicle so that it
can be turned, and confirm that it cannot be turned even when ignition switch is pressed without an
Intelligent Key in the vehicle.
For further information, see the CONSULT-III Operation Manual NATS-IVIS/NVIS.
