Default Traction control, ABS, and Brake lights stay on

Several months ago, my son left the lights on my 05 PT Cruiser on and drained the battery stone cold dead. I jump-started the car from my Dodge RAM truck by connecting the jumper cables to the bolts indicated under the hood for jumping.

The car started right up without any problems; however, immediately the Traction Control, ABS, and Brake lights came on in the instrument panel. They've been on for 4 months now and they come on EVERY time the car is started.

Here's the rub: My Cruiser doesn't have ABS or Traction Control! Did the jump fry my PCM? I loathe taking it to my local Dodge dealer as they are not honest or ethical.

Thanks very much for any input you can offer!!!

Question Re: Traction control, ABS, and Brake lights stay on

Have you tried to pull codes from the OBD system?

Also try resetting everything by taking the negative battery cable off for 5 minutes. Step on the brake pedal. Put it all back together.

OK! Problem solved! After weeks of research and multiple visits to the dealer (yes I broke down and went in), turns out the problem is with the instrument cluster itself. During the jump process, a voltage surge toasted the circuitry in the cluster.

I was sure it was a cooked ECU/PCM, but I was wrong. Guess that's what I get for doing my own thinking.
