Operation Description/Trunk Open

When the Intelligent Key unit 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 sends the request signal to the Intelligent Key. And then, make sure 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 sends the key ID signal to the Intelligent Key unit via remote keyless entry receiver.
Intelligent Key unit receives the key ID signal and compares it with the registered key ID.
If the key ID check result is OK, the Intelligent Key unit sends trunk open request signal to BCM (Body control module) via CAN communication line.
Intelligent Key unit sends 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.
