security light is on and won't start
 

I have a problem that just popped up about an hour ago. To start with it's a 99 bonneville,been running just fine. Tonight my wife went to a party and when she went to leave the car would'nt start,so I got a call and walked 2 miles to see what it was.I'm baffled when i went to start it al the lioghts came on as they should,there was 1 extra light on-the securety light was flashing. Also when I tried to start it the brake light in the car center lit up on the back of the diagram. I'm having a feeling that the abs switch went out,which I really hope it's not that. Any ideas would be great on this matter.It's new to me,I have been working on cars along time and never ran accross this problem.The battery is fully charged and all fuses are good.

Have you checked the error codes?
