My 1009 Caravan does exactly the same thing. It always happens when the battery is disconnected for a period of time on mine. Unfortunately I don't have an answer for you, except to say that there is a particular sequence of button-pushes that will reset the system. I have posted another question on this site concerning this, so maybe between the two of us we'll get an answer!
