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 the outer mirror control ECU assembly (front passenger door) via CAN communication. On receiving the signal, the outer mirror control ECU assembly (front passenger door) operates the vertical and horizontal mirror motors, which are built into the outer rear view mirror assembly (front passenger door), to adjust the mirror surface position.
