Remote Control Door Lock Receiver (RCDLR)

The remote control door lock receiver (RCDLR) is a module that operates the keyless entry system. The RCDLR has an internal antenna that is used to receive radio frequency (RF) communications sent by the keyless entry transmitters. When an RF message is received from a keyless entry transmitter, the RCDLR interprets this signal and will request via serial data that the body control module (BCM) perform the specific function, i.e. door lock or door unlock.
