Principles of Operation
WARNING: This page is about a different car, the 2013 Lincoln MKX and 2013 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
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 controls mostly the IA and related entry/anti-theft systems (such as the power door locks and the liftgate release). The RFA module communicates on the Medium Speed Controller Area Network (MS-CAN). The RFA module controls the following functions:
- Intelligent Access (IA) feature
- Keyless entry keypad illumination
- Liftgate release
- Passive Anti-Theft System (PATS)
- Power door locks
- Remote Keyless Entry (RKE) system
