POWER MIRROR CONTROL SYSTEM(w/ Retract Mirror) Power Mirror Surface Position is not Memorized

SYSTEM DESCRIPTION

When the seat memory switch is operated, the switch input signal is sent via CAN communication from the outer mirror control ECU assembly LH*1, RH*2 to the main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) then sends the memorization request or recall request signals to the outer mirror control ECU assembly LH and outer mirror control ECU assembly RH via CAN communication. The outer mirror control ECU assembly LH and outer mirror control ECU assembly RH memorize the mirror position when a memorization request signal is received, and move the mirror to the memorized position when a recall request signal is received.
