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.
For the linked functions of the sliding roof and roof sunshade refer to Operation Check.
