airbag massage working principle :
Firstly , the driver board giving AC110V to air pump to do working with air and also control the solenoid valve on/off to make the
airbag full air or release air as program requirement . So you should make sure where is the trouble from , air pump or solenoid valve
when the airbag no working. Generally , you can judged by listening and touch , because they are with noise or vibration when
working normally .
