Exclamation 91 LS400 all air suspension problem

I have problems with air suspension. I had parked my car for a couple of month and then I just found out that It is dropped to the almost ground, (all side)
I’m sure It was OK before.
They said when engrain start up; It will pump up, but nothing happen for 30 min.
I cannot believe that the all suspension went bad at same time,
Can anybody help me out???
Is there any checkpoint before I take it to dealer???

dont know how much the following will help but you should give it a try before you take it to the dealership:

is the air suspension light blinking on your dash board? is your air suspension turned on?(check the trunk and air suspension controller to see if it is "ON")

if it isnt blinking then continue to read the following

1st try to put the air suspension on high mode and see if it raises give it a few minutes to pump air into each side....

if no.....then continue to do this

disconnect your car battery for 5 minutes. then reconnect and start the car. see if anything happens

if no.....then

consult the dealership


i hope this will solve the problem. good luck with it
