Only Front Switch Cannot Operate Rear Sunshade: Description

A rear sunshade switch signal is sent from the integration control and panel assembly (No. 2 console switch) to the combination switch assembly (No. 1 console switch). Then the signal is sent through LIN communication to the outer mirror switch assembly, which then sends the signal through CAN communication to the luggage room junction block assembly (rear junction block ECU), and the rear sunshade operates.
