TK icon 3 stop single opening hydro keeps getting fault 1068. I've done all the usual things removed springs bottomed out the jacks, checked dynamic sensors. I get the fault every 24 hours. It resyncs at 1230pm but it is down by the next morning. Today I noticed in the hoist way set up that I do not get my sensors or top UNL to pass. The car runs all the way to the stop ring during hoist way set up. I can turn it back to auto.. It levels down and it ok run normal until it faults out with 1068. I have had several other cars do this but usually fixed with a hard reset to the jacks. This one isn't. Any thoughts would be appreciated
