Both abs and trac loc lights are on in 1998 park ave

Have vehicle scanned for trouble code and may have a damaged abs sensor/ abs circuit or a hub failing

un related. check into wheel speed sensors for a possible problem.

This means there is a problem with the trac and abs system. the way it works is that when the computer sees a problem with the abs or trac system it turns them both off. also if the check engine light is turnned on due to a problem the computer shuts down the trac and abs system as well due to the computer not being able to control the trac or abs system when there is a engine problem.

The first step here would be to have the computer scanned and get any stored codes out to find out where the problem is. Have the computer scanned for codes first.

Diagnose the ABS Braking System, based on the codes you have

MOST OF THE TIME WHEN ABS LIGHT AND TRAC LIGHT TURNS ON.YOU COULD HAVE A BAD WHEEL SPEED SENSOR.BEST TO TAKE CAR TO DEALERSHIP LET THEM DO CODE SCAN ON ABS BRAKE SYSTEM TO SEE WHAT CAUSING THE ABS AND TRAC LIGHT TO TURN ON.

There is an abs sensor in the left front wheel that is the common culprit on 97-2002 park ave, century and regal

It isn't serious. You can drive the car with it not working. It would however be expensive to fix.

Sounds like you have a ABS system fault. Take it to a mechanic, they can retrieve the ABS fault codes.

i have a 98 buick park avenue
i got a problem running it. it start but when i hit the break pedal some light comes out the direction signal and it shuts off i check all the fuse

It is part of the ABS wheel sensors.So yes it is part of the ABS system.
