Incorrect reverse operation of the lid assembly - sunroof
Check guide rail for foreign particles.
• Incorrect reverse operation of the lid assembly - sunroof while driving on rough road
The lid assembly - sunroof has auto-reverse function. When the lid assembly - sunroof is pushed in the opening direction with a force of 100 N (10.2 kgf, 22.5 lbf) or less, the glass lid moves in reverse and then stops.
Therefore, if you operate (open or close) the lid assembly - sunroof 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.
