DESCRIPTION
The multiplex network master switch assembly sends the mirror adjust switch signals to the main body ECU (multiplex network body ECU) via LIN communication. The main body ECU (multiplex network body ECU) then sends the received mirror adjust switch signals to each outer mirror control ECU assembly via CAN communication. Based on this signal, each outer mirror control ECU assembly operates the vertical and horizontal mirror motors to adjust the mirror surface position.
