Emergency retract is activated automatically when the emergency brake is released and the ignition is on, if the jack system looses "hold-up" pressure. Modern Level-Up jacks use system pressure to retract the jacks and hold them up. Thus you have a leak in the jack up system.

So you are saying that the jack system is always on and sensing the hydraulic pressure? So when the pressure falls below a certain threshold, the system comes on and pumps the system back up to hold the jacks in the up position?
Seems like a strange design. I would have thought, that the jacks would be in a "locked - up" position such that if you disconnected the hoses the jacks would not fall.
