Q: What does code U013F mean?

Lost Communication With Pedestrian Alert Control Module. U013F is a generic network communication code indicating that the engine control module or another primary module has lost contact with the pedestrian alert control module over the vehicle's controller area network (CAN) bus. The computer has detected that expected periodic messages from the pedestrian alert module are missing, which typically sets a communication fault rather than a direct component failure.
