POWER MIRROR CONTROL SYSTEM Driver Side Power Mirror cannot be Adjusted with Power Mirror Switch

DESCRIPTION

The multiplex network master switch assembly sends the mirror adjust switch signals to the main body ECU (multiplex network body ECU) via LIN communication. The main body ECU (multiplex network body ECU) then sends the received mirror adjust switch signals to the front multiplex network door ECU (driver door) via CAN communication. Upon receiving the signal, the front multiplex network door ECU (driver door) operates the vertical and horizontal mirror motors, which are built into the outer rear view mirror assembly (driver door), to adjust the mirror surface position.
