Remote Function Actuator (RFA) Module

Principles of Operation

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 (Remote Function Actuator) controls the IA (Intelligent Access) and related entry/anti-theft systems (such as the power door locks and luggage compartment/liftgate release). The RFA (Remote Function Actuator) module communicates on the High Speed Controller Area Network (HS-CAN) and the Medium Speed Controller Area Network (MS-CAN). The RFA (Remote Function Actuator) module controls the following functions:

- IA (Intelligent Access) feature

- Ignition states

- Passive Anti-Theft System (PATS)

- Remote Keyless Entry (RKE) system
