Signal Path

BCM activates inside key antenna and checks that Intelligent Key is in vehicle, when push-button ignition switch operation is performed while ignition switch position is LOCK.
When BCM does not detect a registered Intelligent Key in vehicle, meter display signal is transmitted by BCM to combination meter via CAN communication.
When combination meter receives meter display signal, key ID warning displays.
After 5 seconds are passed since the key ID warning is displayed, key ID verification information displays.
