    Abstract: A method for run time zero byte compression of data on a communication bus of a vehicle includes determining a number of zero bytes provided in a data frame. When there are enough zero bytes, an encoding byte is generated that maps the locations of the zero bytes in the data frame. A data length code related to the number of non-zero data bytes and the encoding byte is provided in a device header. The data length code has a value less than an uncompressed data frame. The compressed data frame is transmitted with the encoding byte and the uncompressed non-zero data bytes. To decompress the compressed data frame, the encoding byte maps the locations of the zero bytes for a data frame. The non-zero data bytes are then provided at the proper locations to recreate the data frame.
