This is the power source circuit for the outer mirror control ECU.

A/T models:

After the ECM receives a reverse signal from the park/neutral position switch, the ECM sends a reverse signal to the outer mirror control ECU via the CAN and BEAN communication systems. The outer mirror control ECU activates the mirror motor in response to the reverse signal.

M/T models:

When the seat memory switch M1, M2 or M3 is pressed, the position control ECU & switch (Seat ECU) transmits a signal of the memorized mirror position to the outer mirror control ECU by way of the power window regulator master switch. Then, the outer mirror control ECU drives the mirror motor.
