Default Dashboard goes crazy, check engine light,oil light......

Hi, I hope that you can help. I have a 2006 PT non turbo with 98,000 miles.
About a month or so ago, The whole dashboard lit up. The Check Engine light, oil light, battery light, and the "RND" transmission lights, all came on at the same time. The speedometer and tachometer did not work, and there was a constant "ding". The temperature guage and the fuel guage were the only ones working. I pulled off the road and did visual checks, everything looked fine. I started the car and drove home, about 20 miles, the dash was still acting up, but the car drove fine. The next day, I started the car, I was on my way to an AutoZone Store, about 10 miles away, when the dash returned to normal, except for the Check Engine light. At the AutoZone store I asked for the car to be scanned. The scanner came up with the code U0002. They could not tell me what the code meant. Since then the dash has acted up but the Check Engine light stays on with the "ding". Has this happened to any one?

I don't know PT cruisers too well, yet, but I do know alot of times when Dash lights and Gauges go crazy, it is related to the charging system in some way. Either your battery is shorting out and dying, ground or positive battery lead is corroded or, your alternator is failing.

I can't find anything to do with a PT Cruiser with that fault code. A search did find that code for a Mercedes to do with the electrical system.
