ROOF SUNSHADE SYSTEM Door Lock Linked Close Function does not Operate

DESCRIPTION

The roof sunshade ECU (sliding roof drive gear assembly) receives a door lock linked close operation request signal from the main body ECU (multiplex network body ECU) via the LIN communication when the wireless door lock function, key-linked door lock function or entry door lock function is operated with the power switch off. Then, the roof sunshade ECU (sliding roof drive gear assembly) activates the roof sunshade motor to close until it is fully closed.
