BCM (Body Control Module)
WARNING: This page is about a different car, the 2004 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.
The BCM reads the air pressure signal received by the remote keyless entry receiver, and controls the combination meter warning lamp and the buzzer operations as shown below. It also has a judgement function to detect a system malfunction.
