U0112 BMW Description
This fault code is stored in a control module when communication is lost or a message corrupt. Communication protocols have strict error handling processes for data transfer. If a module or a component that can communicate on the data bus returns a negative acknowledgment an error flag will be set and the module transmitting the erroneous data may become disconnected from the network. The affected module will go to a bus off state if the error count is greater than 256.
