Remote Function Actuator (RFA)

The Remote Function Actuator (RFA) module is part of the remote keyless entry system. The RFA module sends a serial data message to the Body Control Module (BCM) through the Class 2 serial data line. The RFA Transmitter (Key Fob) sends the following commands to the RFA Module:
^ The door lock and unlock control
^ The rear compartment release
^ The panic alarm

The RFA module then sends a serial data message to the BCM in order to perform the appropriate function. For programming of the RFA System refer to Keyless Entry.
