SLIDING ROOF / CONVERTIBLE  PANORAMIC MOON ROOF SYSTEM(Production Date from 2023/04)  Panoramic Moon Roof System does not Operate  


DESCRIPTION

The sliding roof ECU (sliding roof drive gear assembly) and roof sunshade ECU (sliding roof drive gear assembly) receive each other's position information from the main body ECU (multiplex network body ECU) via LIN communication.

The sliding roof ECU (sliding roof drive gear assembly) and roof sunshade ECU (sliding roof drive gear assembly) receive signals from each switch, and operate their built-in motors.
