System Description

When the shift lever is moved to the R position while the ignition switch is on (IG), the ECM receives a reverse position signal from the park/neutral position switch. After receiving the signal, the ECM sends it to the network gateway ECU via CAN communication. The network gateway ECU sends the signal to the main body ECU via BEAN communication. After receiving the signal, if the rear sunshade is raised, the main body ECU turns on the rear sunshade relay to lower the rear sunshade.
