DOOR REQUEST SWITCH : System Description

INFOID:0000000000961092

Only when pressing the request switch, it is possible to lock and unlock the door by carrying the Intelligent
Key.
• The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock/

unlock function) by carrying the Intelligent Key, which operates based on the results of electronic ID verifica-
tion using two-way communications between the Intelligent Key and the vehicle (BCM).

CAUTION:

The driver should always carry the Intelligent Key

• If an action that does not meet the operating conditions of the Intelligent Key system is taken, the buzzer

goes off to inform the driver (Warning chime function).

• When a door lock is locked, unlocked or trunk open with request switch or remote controller button opera-

tion, the hazard lamps flash and the Intelligent Key warning buzzer or horn sounds (Hazard and buzzer/horn
reminder function).

• The settings for each function can be changed with the CONSULT-III.
• If an Intelligent Key is lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can be

registered.

• It is possible to perform a diagnosis on the system and register an Intelligent Key with the CONSULT-III.

OPERATION DESCRIPTION/DOOR LOCK/UNLOCK

• When the BCM detects that each door request switch is pressed, it starts the outside key antenna and inside

key antenna corresponding to the pressed door request switch and transmits the request signal to the Intelli-
gent Key. And then, check that the Intelligent Key is near the door.

• If the Intelligent Key is within the outside key antenna detection area, it receives the request signal and

transmits the key ID signal to the BCM via remote keyless entry receiver.

• BCM receives the key ID signal and compares it with the registered key ID.

Intelligent Key as long as key IDs are different.

The outside key antenna detection area of door lock/unlock function
is in the range of approximately 80 cm (31.50 in) surrounding the
driver and passenger door handles (1).

When an UNLOCK signal is sent from door request switch (driver side or passenger side) once, driver's door
will be unlocked.
Then, if an UNLOCK signal is sent from door request switch (driver side and passenger side) again within 5
seconds, all other door will be unlocked.

HAZARD AND BUZZER REMINDER FUNCTION

gent Key warning buzzer will blink or honk as a reminder.
When doors are locked, unlocked by each request switch, IPDM E/R honks Intelligent Key warning buzzer as
a reminder and transmits hazard request signal to BCM via CAN communication line.
BCM flashes hazard warning lamps as a reminder.
