Abs Light Come On

I Have 97 Gtp With 140 000 And It Abs Light Comes On What Should I Do Could It Be The Brake Need Changing

The ABS light has nothing to do with needing to change your brakes. It indicates a problem with the anti-lock system. It could be anything from a bad hub bearing/wheel speed sensor, to a broken/corroded wire, to a bad EBCM. Your best bet would be to have it scanned with an ABS capable scan tool to see what is tripping the ABS light.
IF only the ABS light is on, and the Trac-off light isn't, then it's most likely an EBCM issue. If the trac-off light is also lit, then it's most likely a bad hub or broken wire.

Thankyou For The Info

98 GTP
I have the same thing. It has been raining here a lot. On my way home the abs light came on and so did the tcs light. How would the hub go bad and what price are we talking to get it fixed?

Thank you.

now the abs light has gone off (did nothing to it)
