POWER MIRROR CONTROL SYSTEM Reverse Shift-linked Function of Power Mirrors does not Operate

DESCRIPTION

EV 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. Each outer mirror control ECU assembly then performs control in response to the reverse signal.
