Not a very good dealer , you have to use IDS to unlock the adjusters electronically , all it is doing is recovering its "set" position as it sees it , the snap on scanner does not have this option in its menus , think the only one you can use is a IDS , unless there is an update for your scanner online , just a thought .

One cheat you could try is to jack the back end of the car up to kid the system that it is nose down , allow the lights to find their new level then disconnect battery for an hour , drop back end down again and reconnect battery , that would be my only shout without a scanner at hand .
