2001 Buick Century Low Trac, Anti-Lock Light came on

I had spun my tires on wet road and had ran thru some water on the right side of my car. My low trac light & anti-lock light came on. I had turned car off, restarted light went off but has since came back on. This car was bought from a 90 year old Lady and is in Mint condition. Any suggestions would be deeply appreciated. Thanks, Eddie
