Principles of Operation: Notes

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
