Abstract
The present invention relates to an improved method for transmitting information on a bus assigned to an electrical controller including a main unit and at least one secondary unit. According to the invention, the reliability of data transmission via the bus is enhanced by checking each data transmission for errors. When a faulty data transmission is found, the data transmission is repeated. An error message will not be generated until a faulty data transmission is detected for a predetermined number of successive transmissions.
