Claim 11:
12. A method for error signaling for a message received in a serial bus system, the method comprising the following steps:
creating, using a user station of the bus system, a message which is to be transmitted serially to at least one further user station of the bus system; and
transmitting the created message via a bus line to at least one further user station of the bus system, an ACK time window for an ACK signal and/or a NACK time window for a NACK signal being provided in the transmitted message for a signaling of whether or not at least one further user station has identified an error in the received message;
wherein, in the step of transmitting the created message, no level is driven on the bus line by the user station in the ACK time window and/or the NACK time window, such that a recessive bus level arises with a value between a first bus level value and a second bus level value.
