System Description

On receiving a reverse signal from the park/neutral position switch, the ECM 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.

HINT: 

The reverse shift-linked function will not activate when the mirror select switch is in the neutral position (off).
