The Remote Function Actuator (RFA) module is a multifunction electronic module that controls many of the vehicle systems. The RFA module communicates on both the Medium Speed Controller Area Network (MS-CAN) and the High Speed Controller Area Network (HS-CAN). Most of the RFA module functions utilize hardwired inputs and/or outputs. The RFA module controls or monitors the following:
- Anti-theft perimeter alarm
- Intelligent Access (IA)
- Keyless entry keypad
- Luggage compartment lid release
- Passive Anti-Theft System (PATS)
- Power door locks
