Intelligent Key is near the back 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.
• If the verification result is OK, BCM transmits the back door open request signal to automatic back door con-
trol unit via CAN communication.

back door is open.
• When the back door is open, automatic back door system performs waiting operation for next back door
close operation.
