Signal Path

WARNING: This page is about a different car, the 2018 Infiniti Q60. However, it is still accessible from the selected car via links, so may be relevant.

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.
