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

SYSTEM DESCRIPTION

The multiplex network master switch assembly detects the mirror adjust switch status and sends the 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 adjust switch signal to each outer mirror control ECU (both driver and front passenger sides) via CAN communication. On receiving the signal, each outer mirror control ECU operates the vertical and horizontal mirror motors to adjust the mirror surface position.
