B10C4 Description

 

The Remote Function Actuator (RFA) Module interprets radio frequency signals from the Remote Functions Receiver (RFR) Module and Intelligent Access (IA) key transmitters. The RFA module receives input signals from various modules and other components. Based on this information, the RFA module generates an output signal to control various components such as the door locks and the liftgate. The OBDII code sets when the RFA module detects the right rear unlock sensor activated for more than 5 minutes.
