Failure turn of glass lid |

• Failure turn of glass lid while driving rough road.
Glass lid has auto-reverse function. When specified or more force is applied to the glass lid, the lid turns back and stops. When operating the glass lid (open or close) while driving the rough road, the lid judges vibration as a force and may causes failure turns. When the failure turn is occurred, need to perform the initialize operation with following procedure.
1. Tilt up the glass lid.
2. Release the switch once, and press the tilt up switch again for 15 seconds.
3. When the glass lid is raised a little and returned to tilt up position, release the switch for the moment. (Initialization of position detecting function)
4. Keep pressing the tilt up switch within 5 seconds from releasing the switch. The glass lid will tilt down → slides open → slides close automatically. (When more than 5 seconds pass, the position detecting function is cancelled.)
5. Initialize operation is completed.
