As per DAP831 to clear the service reset message…
Press mode until Odometer Appears / THEN press Set until Service appears / THEN Press&Hold Set until “reset service interval” clears (Approx. 10 seconds)
To turn off ABS and get the not legal! message, after you have broken 4 mph and the abs cycles on. Stop the bike and you hold mode and the blank button for 10 seconds until you see the release button message. Then take your illegal bike and back it in all you want.
