DESCRIPTION
A switch signal of the outer mirror switch is transmitted to the selected outer mirror control ECU by way of the main body ECU RH. Then, the outer mirror control ECU activates the mirror motor to move the mirror UP, DOWN, RIGHT or LEFT in response to the input.
Mirror control switch and memorized mirror position signals (from the front power seat switch (position control ECU)) are sent to the mirror control ECU. The mirror control ECU moves the selected mirror UP, DOWN, LEFT or RIGHT in response to the input.
