my abs , service brake system light is on and my door dinger goes off with key on and door shut. What's causing this?

I'm having the exact same problem.Checked grounds thought I had it,drove for 15 mins. and the lights came back on,then all the warning lights came on.I think I screwed mine up by trying to start with a battery charger.IDIOT

I just fixed the problem now. It was a body ground problem,add a extra ground from body to block and it should fix your problem.
