POWER MIRROR CONTROL SYSTEM(w/ Retract Mirror) Power Mirror cannot be Adjusted with Power Mirror Switch

DESCRIPTION

When the outer mirror switch assembly mirror select switch is operated, right/left selection signals are sent to the main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) sends the received right/left selection signals to the outer mirror control ECU assemblies via CAN communication.
