DESCRIPTION
The multiplex network master switch assembly sends the auto retractable outer mirror switch signal to the main body ECU (multiplex network body ECU) via LIN communication. 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.
