Operation Description/Trunk Open

When the BCM detects that trunk open request switch is pressed, it starts the outside key antenna (trunk room) and inside key antenna corresponding to the pressed trunk open request switch and transmits the request signal to the Intelligent Key. And then, check that the Intelligent Key is near the trunk.
If the Intelligent Key is within the outside key antenna (trunk room) 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 transmits the trunk open request signal and sounds Intelligent Key warning buzzer 4 times at the same time.
When BCM receives the trunk open request signal, it operates the trunk lid opener actuator and opens the trunk.
