MIRROR (EXT)  POWER MIRROR CONTROL SYSTEM(w/ Memory)  Reverse Shift-linked Function of Power Mirrors does not Operate  


DESCRIPTION

The hybrid vehicle control ECU sends the reverse signal to the main body ECU (multiplex network body ECU) via CAN communication. When receiving the reverse signal, the main body ECU (multiplex network body ECU) sends the reverse request signal to each outer mirror control ECU assembly. Based on the signal, each outer mirror control ECU assembly then performs control.
