Remote Function Receiver Module
WARNING: This page is about a different car, the 2010 Chevrolet Camaro. However, it is still accessible from the selected car via links, so may be relevant.
The remote function receiver module is connected to the BCM with a dedicated link. When a button is pressed on a keyless entry transmitter, the remote function receiver module receives this signal and sends the request to the BCM. The BCM interprets the signal and performs the specific function, i.e. door lock, door unlock, or vehicle locate.
