abs light- trac off- serv eng soon

hello forum! would appreciate any info regarding these multiple warning lights that came on as I was driving. It happen once before a couple days before and I turned the car off and later the lights went off. a day later they went on again. Could it be a loose part or something? I had a brake job, but that was just pads. I have a 2000 GR AM GT. The brake job was over three months ago, and I had not experienced any problems.

Welcome to the forum. The lights you're describing indicate one of two things 1) that you have a bad wheel bearing hub assembly(s) or 2) that you have a bad wheel speed sensor in one of your hubs, so your car thinks that is has a bad hub. My guess would be the 2nd, due to the fact that it reset itself when you turned your car off. Did you recently hit a bump or drive in adverse conditions?

GA's have finicky brake systems. If you drive 6 feet with your hand brake on it will set off the codes (off topic)

You have a simular problem as me. When they replaced the pads did they service the rotors? Warped rotors on new pads will make your abs light come on and off. When your abs light comes on it means the abs is turned off. The service Vehicle Soon light will come on aswell. Take your wheels off and see if the pads are excessively wearing one side more than the other. If thats all ok then go with Ridenours diagnosis. My step should be checked before his as a money saving thing. Ridenours advice is good advice.
