Principles of Operation

The Remote Function Actuator (RFA) module is only equipped when the vehicle has the Intelligent Access (IA) feature. On vehicles equipped with this option, the RFA (Remote Function Actuator) controls mostly the IA (Intelligent Access) and related entry/anti-theft systems (such as the power door locks and the liftgate release).
