ABS light on...?

95 lumina ls 150,000 km..have had this problem before but it went away for a few months but now its back. While driving the abs light will turn on ..it always starts after a little driving and doesent turn onn untill i shut the car off. Have had it in the garage and replaced, the sensor, and the relay. What else could it be? sometimes it doesent turn on at all!

you might have to do what i did. i went to a local repair garage and had them put on this huge code scanner. just ask if they can get codes for ABS. with mine they pinpointed that i needed a new front left wheel bearing.

yea i did that twice..first it was the relay, it was replaced. The second time it was a sensor...so now its dooing it again..but the abs still works.

You need t get the ABS code with a ABS scanner.
When the light is on ABS is not working.
Post back code for more help.

hey man I know this sounds strange but try flushing your entire brake fluid system, the fluid could be so old it heats up quicker and causes brake failure and/or false readings on scanners. I say this only because you've changed sensors. let me know if that helps any? good luck!
