WARNING: This page is about a different car, the 2010 GMC Terrain and 2010 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.
The remote control door lock receiver is responsible for receiving signals from the keyless entry transmitters. The remote control door lock receiver receives constant B+ and ground and communicates with the BCM via two serial data circuits. When a signal is received by the remote control door lock receiver, a message is sent to the BCM via serial data indicating the function that has been requested.
