Section 12 (Keyless Entry System - Remote): Description

WARNING: This page is about a different car, the 1997 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

Remote Keyless Entry (RKE) system is controlled by Remote Function Actuation (RFA) system. RFA system allows transmitter remote control of various vehicle systems without physical contact of switches on vehicle and Tire Pressure Monitoring (TPM) system functions.

RFA system consists of a transmitter located on drivers key fob, a remote control door lock receiver, and an integral antenna. The RFA system does not directly control system functions. RFA system uses one of the following systems to perform driver commands:

Body Control Module (BCM) for Universal Theft Deterrent (UTD), hatch release, horn and vehicle light control.
Door Control Module (DCM) for all door lock functions.
Instrument Panel Cluster (IPC) for RFA system programming and vehicle personalization functions.

When RFA system receives a transmitter command, a message is sent through the serial data line to applicable system module.

RFA system should be used as a supplement to vehicles conventional operated lock/unlock system. It is not meant to replace, but should be used in conjunction with door lock key. RFA system could disable due to radio frequency interference or a low transmitter battery. Always maintain vehicle access with a door key. The remote control door lock receiver is located over left rear wheelwell. The receiver receives and transmits information to other vehicle systems to perform specific functions.
