DESCRIPTION
The multiplex network master switch assembly sends the 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) then sends the mirror retract/return signal to each outer mirror control ECU assembly via CAN communication. Based on the signal, each outer mirror control ECU assembly retracts or returns its corresponding outer rear view mirror assembly.

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.
