POWER MIRROR CONTROL SYSTEM (w/ Memory) Power Mirrors do not Return to Memorized Position

SYSTEM DESCRIPTION

If any of seat memory switches M1, M2 or M3 is pressed, the outer mirror control ECU assembly detects the seat memory switch status and sends the switch signal to the position control ECU and switch assembly through the CAN communication line. The position control ECU and switch assembly operates the power seat motors to move the seat to the memorized position and then sends back a reproduction signal to the outer mirror control ECU assembly through the CAN communication line. When the outer mirror control ECU assembly receives the reproduction signal, the ECU operates the vertical and horizontal motors built into each outer rear view mirror to adjust the mirror surface to the memorized position.
