What Does the B1373 Code Mean?

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 receives no response from the right front door unlock sensor when voltage and ground are applied to the sensor after detecting vehicle speed.
