DESCRIPTION
The outer mirror switch assembly sends the auto retractable outer mirror switch signal to the main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) sends the auto retract/return signal to the outer mirror control ECU assemblies via CAN communication, which then controls the mirrors.
When the outer mirror control ECU assemblies receive a door lock output signal from the main body ECU (multiplex network body ECU) while the auto retractable outer mirror switch is on, the outer mirror control ECU assemblies operate the retract motors built into the outer rear view mirror assemblies to retract or return the outer rear view mirror assemblies.

CAUTION / NOTICE / HINT
Note
The power mirror control system (w/ Memory) uses the CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the power mirror control system (w/ Memory) after confirming that the communication systems are functioning properly.
Before replacing the main body ECU (multiplex network body ECU), refer to Service Bulletin.
As the door control battery is installed between the vehicle battery and main body ECU (multiplex network body ECU), first perform the inspections in On-Vehicle Inspection to confirm that there are no malfunctions in the power source circuit for the main body ECU (multiplex network body ECU) before performing this troubleshooting procedure.*
