When you get this warning, turn the system on, and re-store jacks. Check to be sure all springs are strong; if it take a long time to store, they could be weak. Check and verify that the sensor connection on top of the pistons are good. If one of the jack down lights for a particular jack lights up, this could be a bad sensor, spring tension or a hydraulic line could be too close to exhaust heat, causing some increase in pressure.
