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 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.

NOTICE:
First perform the communication function inspections in How to Proceed with Troubleshooting
to confirm that there are no CAN communication malfunctions before troubleshooting
this problem.
