Hmmm, the only time I've seen that light come on was just recently after an Upsolute ECU Upgrade (battery disconnect). To clear the error...

Start vehicle > leave in Park/Neutral > Turn steering wheel all the way to the left and hold for 5 seconds > Turn steering wheel all the way to the right and hold for 5 seconds > Then bring it back to center > Light should go off

That should clear the error. Why it is coming on doing 65 is definitely scary!
