You need something like a snapon tools diagnostic tool, or the dealer level SDS computer to put it into "rodeo" mode.

Something like the Foxwell NT624 or Autel Maxidiag MD802 claim they might work. I think there's a sticky thread on the foxwell on the forum, so might be worth reading to see if there's issues with it.
