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 theft-alarm siren (via LIN cutoff control unit^*4 )^*5 and the theft-alarm siren^*5 . The master ECU requests these slave ECUs to communicate each other via communication lines.

NOTE:

^*1 : ETACS (Electronic Time and Alarm Control System)
^*2 : Vehicles with sunroof
^*3 : Vehicles with auto light function
^*4 : The LIN cutoff control unit is a relay circuit to turn ON/OFF the LIN communication of theft-alarm siren. An ECU is not incorporated in the LIN cutoff control unit.
