SYSTEM DIAGRAM

DOOR REQUEST SWITCH OPERATION

Only when pressing the door request switch, it is possible to lock and unlock the door by carrying the Intelli-
gent Key.

OPERATION DESCRIPTION

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

inside key antenna corresponding to the pressed door request switch and transmits the request signal to the
Intelligent 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 locks/unlocks each doors.
• BCM sounds Intelligent Key warning buzzer (lock: 2 times, unlock: 1 time) and blinks hazard warning lamps

(lock: 2 times, unlock: 1 time) at the same time as a reminder.

OPERATION CONDITION

If the following conditions are satisfied, door lock/unlock operation is performed if the door request switch is
operated.

*: Even with a registered Intelligent Key remaining inside the vehicle, door locks can be locked/unlocked from outside of the vehicle with
a spare Intelligent Key as long as key IDs are different.
