tcs not working & abs not working either

On my 1999 mazda millenia the tcs & abs warning lamps are on ,does anyone know what is wrong ?

I have a 2002 Pontiac Grand Prix that's doing the same thing. Let me know if yours blows up before mine so I can get mine checked out. I wrecked mine over the summer though. I figure it stems from that. I think I pressed the breaks too hard and may have crystalized them. LMK. *G*
