WARNING: This page is about a different car, the 2020 Infiniti QX60. However, it is still accessible from the selected car via links, so may be relevant.

The buzzer for the warning chime system is installed in the combination meter.
The buzzer sounds when the combination meter receives a buzzer output signal from the BCM.
The BCM receives signals from various units and transmits a buzzer output signal to the combination meter with CAN communication line if it judges that the warning buzzer should be activated.
