Remote Function Actuator (RFA) Module

The RFA  module is responsible for controlling the power door locks and the Intelligent Access (IA) features. It uses the antennas in the front exterior door handles and the liftgate Intelligent Access (IA) antenna and the TPM  module to receive the Intelligent Access (IA) key data. The RFA  module receives direct input from the TPM  module over a dedicated single wire network and is hardwired to the antennas. The power door lock actuators, exterior power liftgate switch, and the keyless entry keypad are also hardwired to the RFA  module. The RFA  module receives the door lock control switch input from the BCM  over the MS-CAN  .
