Communication Method
As shown in the figure, SWS communications connect the ETACS*1 -ECU, the column switch (in the column-ECU), the front-ECU, and the sunroof-ECU. CAN*2*3 communications connect the ETACS-ECU, the powertrain control module, the A/C-ECU, the SRS-ECU, the combination meter, the ABS-ECU, and the middle-grade multi-center display. These two communications groups are connected to form a dedicated network for sending multiplex data.
