General Information: Structure
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 lighting control sensor*2 , the power window main switch, the theft-alarm siren (via LIN cutoff control unit*3 )*4 and the theft-alarm sensor*4 . 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 lighting control sensor
- *3 : 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.
