The keyless entry system has the following main components:
^ The transmitters
^ The Body Control Module (BCM)
^ The Remote Control Door Lock Receiver (RCDLR) which was added midyear to certain vehicles. When you press a button on the transmitter, the transmitter sends a signal to the BCM or to the RCDLR. The RCDLR receives the signal and sends a class II serial data message requesting the appropriate function from the BCM. On vehicles with ONLY a BCM, the BCM receives and interprets the signal and activates the requested function.
When you press a button on a transmitter, the transmitter sends a signal to the BCM. The BCM interprets the signal and activates the requested function.
