Front and Rear Switch Cannot Operate Rear Sunshade: Description

A rear sunshade switch signal is sent from the front switch (No. 2 console switch) to the outer mirror switch through LIN communication. The outer mirror then sends the signal to the rear junction block ECU through CAN communication, and the rear sunshade operates. For the rear switch (curtain switch), a rear sunshade signal is sent from the rear power seat module switch to the rear junction block ECU, and the rear sunshade operates.
