I replaced the battery, but the suspension leveling and other lights turn on!

What is your question?

I just replaced my battery in my 94 740iL. It drove fine for about 2 days, 65 miles worth. However, now on day 3, all the electronic control lights are coming on again, and when I attempt to turn, the anti lock system kicks in and wont allow me to make a sharper turn, its quite scary when your in a lot of traffic. It only happens when I try to turn. When I am driving straight, the suspension leveling warning comes on the dash display, but the other lights stay off. I am completely out of ideas, and I am terrified that it is going to be an extensive fix. Someone please help!!
