The Brake System Control Module (BSCM) monitors the Steering Angle Sensor (SAS). The BSCM Module sets this DTC when it is detected that the SAS has not learned the neutral position. The Electric Power Steering (EPS) Module outputs a signal indicating that the learning procedure has not been performed over the Controller Area Network (CAN) CAN_FD14 bus in the EPS controller.
