WARNING: This page is about a different car, the 2013 Ford Fiesta. However, it is still accessible from the selected car via links, so may be relevant.
The Remote Function Actuator (RFA) module is only on vehicles equipped with the Intelligent Access (IA) feature. On vehicles equipped with this option, the RFA controls the IA and related entry/anti-theft systems (such as the power door locks and luggage compartment/liftgate release). The RFA module communicates on the High Speed Controller Area Network (HS-CAN) and the Medium Speed Controller Area Network (MS-CAN). The RFA module controls the following functions:
- IA feature
- Ignition states
- Passive Anti-Theft System (PATS)
- Remote Keyless Entry (RKE) system
