Front And Rear Switch Cannot Operate Rear Sunshade

INTERIOR: REAR SUNSHADE SYSTEM: Front and Rear Switch Cannot Operate Rear Sunshade
- Front and Rear 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 outer mirror switch assembly through LIN communication. The outer mirror switch assembly then sends the signal to the luggage room junction block assembly (rear junction block ECU) through CAN communication, and the rear sunshade operates. For the curtain switch assembly, a rear sunshade signal is sent from the rear power seat switch to the luggage room junction block assembly (rear junction block ECU), and the rear sunshade operates.
