WebMar 22, 2024 · The second checksum is calculated just the same as the LIN bus checksum, but over all bytes in the LIN Transport Layer message (starting with 54 01). The checksum byte itself must be set to 00 or be ignored for the checksum calculation. WebFigure 1 shows a typical LIN Protocol configuration. The bus uses a single wire pulled high through a resis-tor with open collector drivers. A Dominant state is sig-naled by a ground level on the bus and occurs when any node pulls the bus low. A Recessive state is when the bus is at V BAT (9 - 18V) and requires that all nodes let the bus float.
