Incorrect reverse operation of the lid assembly front while driving on rough road

The lid assembly front has auto-reverse function. When the lid assembly front is pushed in the opening direction with a force of 100 N (10.2 kgf, 22.5 lbf), the glass lid moves in reverse and stops.

Therefore, if you operate (open or close) the lid assembly front while driving on rough road, the vibration may be judged as a force and the lid may incorrectly move in the reverse direction.

When the incorrect reverse operation is occurred repeatedly, perform inspection around the sunroof frame. If there are no problems, perform the initialization operation with following procedure.
