Service engine soon light comes on , anti lock & track light off

I am assuming its not the service engine soon light it is probably the service vehicle soon light, There are 2 lights service vehicle soon upper left side, and service engine soon upper right side.

When all these come on at the same time it is the wheel bearing sensor. Usually the wheel bearing needs to be replaced which houses the sensor. A sure way to check is to press your sls button by your shifter and see if the light goes out, If it does not, u will need to have a wheel bearing put in.

I just put in new fron pads in my 2000 buick century and the track off and the anti lock brake light and the service engine soon stays on

You will need to have it scanned for codes.

CHECK ALTERNATOR OUTPUT.MAKE YOUR VOLTAGE OUT PUT IS 13.5 TO 14.5 VOLTS.IF NOT ALTERNATOR BAD IF ALTERNATOR GOOD THE DEALERSHIP HAS TO HOOK CAR TO DIAGNOSTIC TO CHECK THE ENGINE PCM CONTROLS AND ABS BRAKES AND TRAC.SYSTEM.REASON I SAID ALTERNATOR BECAUSE I SEEN ALTERNATOR GO BAD UNTIL IT OUTPUT WAS LOW CAUSING CHECK ENGINE LIGHT AND ABS LIGHT TO COME ON.

you need to extract the engine code so you can find out what is wrong with it. you can go to any parts store and they will do it for free

the anti-lock and traction lights will come on together if there is a common problem with the two, since they are closely related. may be a wheel speed sensor or something similar. the service engine soon light indicates a problem with the engine computer, can be anything from an emission system problem or an engine performance problem. all of these lights can come on with no apparent running problems on the car. the service vehicle soon light is basically a maintenance reminder, an oil change light. take the car into a shop and have the codes read for these lights.

You need a new wheel bearing, This also happened to my olds alero, make sure 2 jack up each tire 1 at a time and pull back and forth on them checking for play, once you have found the 1 that has play or wobbles that is the 1 that needs a new wheel bearing

There could be a hundred causes for a check engine light. First step is to hook up a computer scan tool and see what codes the computer has. The next step depends on the codes.

Please go for a scan as it will reveal codes that correspond with whatever problems the car has.

Anti-Lock and Trac Off lights are lit on my 1999 Alero, as well. They usually come on after about 5 minutes of driving, but are not always on when I start the car.
