Communication Method

WARNING: This page is about a different car, the 2004 Mitsubishi Galant. However, it is still accessible from the selected car via links, so may be relevant.

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.

NOTE: *1: ETACS: Electronic Time and Alarm Control System
NOTE: *2: CAN: Controller Area Network
NOTE: *3: For details on CAN, see CONTROLLER AREA NETWORK (CAN) .
