Power Mirror cannot be Adjusted with Power Mirror Switch [11/2023 - ]: Description

The outer mirror switch assembly sends the mirror adjust switch signals to the main body ECU (multiplex network body ECU). 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.
