REAR DOOR SUNSHADE SYSTEM Only Front Switch cannot Operate Right and Left Door Sunshade

DESCRIPTION

A rear door 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. The outer mirror switch assembly then sends the signal to the rear multiplex network door ECU LH or rear multiplex network door ECU RH through CAN communication, and the rear curtain sub-assembly LH or rear curtain sub-assembly RH operate.
