If it is both of those and your fluid is fine, I know my buddy has an Oldsmobile Intrigue and his does the same...it's a speed sensor in the wheel well that's lose and needs to be remounted. It sends the speed to the ABS & trac system.
I'd look into that if it's not your fluid...there's a wire harness attached to your wheel area, it's hard to miss.
thanks everyone, it was low brake fluid. what a load off. the last time I got two lights lit one was brake, the other was anti lock. that one cost me a lot. one of the rear elec senders had to be replaced. again thanks. michael
