Hello and thanks for your question.
I have enclosed instructions below for removal of the air spring solenoid as if it were non functional. To remove the air spring solenoid functional you need a scanner to vent the bag. This procedure allows you to vent the bag by turning the solenoid to the first detent to release the air pressure. You want the body supported before venting the bag so it does not drop and cause injury. The best bet is to jack up the body slightly higher then settled ride height and support in that position.
