Thanks Carl. We did put in the Lift/Lower Pot. The tech said the system would not relearn and he had to set the lift/lower pot to 400 ohms at neutral so it would learn the handle and it still showed a code 81. We never had a problem with the horn sounding and the unit continuing to raise after handle release until this new pot was put in. The Tech is now indicating the unit may need the vehicle manager priced over 2k but he seems very unsure. Looking for other possible solutions. The part installed was NA014981

Thanks
Mike
