|
Panoramic Moon Roof System does not Operate |
DESCRIPTION
The sliding roof ECU (sliding roof drive gear assembly [sliding roof]) and roof sunshade ECU (sliding roof drive gear assembly [roof sunshade]) 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 [sliding roof]) and roof sunshade ECU (sliding roof drive gear assembly [roof sunshade]) 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.
