Lost Communication With Heated Steering Wheel Module. U0229 is a generic network communication code indicating that the module responsible for the heated steering wheel has stopped reporting on the vehicle's Controller Area Network (CAN) bus. The computer that monitors that bus, often the body control module, has detected a loss of the periodic messages it expects from the heated steering wheel module, so it flags the circuit as offline.
