Remote Control Door Lock Receiver (RCDLR)
WARNING: This page is about a different car, the 2002 Oldsmobile Aurora and 2001 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
The keyless entry system is an internal function of the remote control door lock receiver (RCDLR).
The keyless entry system can arm and disarm the CTD system. When the RCDLR receives a door lock or unlock signal from the transmitter, the RCDLR sends a class 2 message to the rear integration module (RIM) in order to perform the appropriate arm/disarm functions.
