Remote Function Actuator (RFA) Module

On vehicles with push button start, the RFA receives passive key data and keyless entry lock/unlock requests from the RF receiver via a LIN. It communicates this information to the BCM. For more information, Refer to: Handles, Locks, Latches and Entry Systems - Vehicles With: One-Touch Open Driver Window - System Operation and Component Description .

The RFA also works with the BCM and PCM to control the PATS function. For more information, Refer to: Passive Anti-Theft System (PATS) - System Operation and Component Description .

The RFA module requires key programming when replaced. Refer to: Passive Anti-Theft System (PATS) Parameter Reset .
