REAR SUNSHADE SYSTEM Only Front Switch Cannot Operate Rear Sunshade

DESCRIPTION

A rear sunshade switch signal is sent from the integration control and panel assembly to the combination switch assembly. 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.
