Master and slave ECUs are connected to the LIN bus lines. The master ECU is the ETACS^*1 -ECU, and the slave ECUs are the column switch (column-ECU), the power window main switch, the sunroof-ECU^*2 and the lighting control sensor^*3 . The master ECU requests these slave ECUs to communicate each other via communication lines.
