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.

CAUTION / NOTICE / HINT
Note
The power mirror control system (w/ Memory) uses the CAN communication system and LIN communication system. Inspect the communication functions by following How to Proceed with Troubleshooting. Troubleshoot the power window control system after confirming that the communication systems are functioning properly.
Before replacing the main body ECU (multiplex network body ECU), refer to Service Bulletin.
