DOOR REQUEST SWITCH : System Description

INFOID:0000000005146876

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 or unlocked with request switch or remote controller button operation, the hazard

lamps flash and the Intelligent Key warning buzzer or horn sounds (Hazard and buzzer/horn reminder func-

tion).

registered.

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

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.

• BCM sends the door lock/unlock signal and sounds Intelligent Key buzzer warning (lock: 2 times, unlock: 1

time) at the same time as a reminder.
