DESCRIPTION

If either the M1, M2 or M3 seat memory switch is pressed, the outer mirror control ECU assembly (driver door) detects the seat memory switch status and sends the switch signal to the main body ECU (multiplex network body ECU) via CAN communication. The main body ECU (multiplex network body ECU) sends back reproduction signals to each outer mirror control ECU assembly via CAN communication. When receiving the reproduction signals, each outer mirror control ECU assembly operates the vertical and horizontal mirror motors, which are built into the outer rear view mirror assembly, to adjust the mirror surface to the stored position.
