A: 1.Check the connection circuits of the emergency switch to the sunroof and the front and rear doors. Verify whether the sunroof and the front and rear doors are connected in series and are connected to the control module.
2.Check whether the signal voltage of the roof window circuit and the front and rear door control circuits on the measurement control module is normal (around 12V).
3.If the signal voltage of the skylight circuit is normal but there is still no response, it indicates that the skylight is locked by screws. Remove the screws and it can be used normally.
4.Connect the access control input in the controller above the sliding door and the GND to the ports of control module 70/71.
