My take on this is the bike has lost power, battery flat or loose connection, something like that. Your date & clock would reset , dunno the start date, but something like 2010 & when that happens you will get the service light show up & stay on. Check you date & clock, reset them to the correct time & of course, make sure you've got a charged & well connected battery first. Once your date & time are set correctly the service wrench will go away till the proper mileage or date is reached.
