    did you rest the light by the procedure in the owners manual?

  • dockw Jun 05, 2010

    Not that I know of. I don't have an owner's manual for this vehicle. I took it to the dealership I bought the car from for the front hub replacement.

    I even took it back there this morning.

    please clarify what light is on exactly? oil life?

  • dockw Jun 05, 2010

    Hi--thank you for your advice so far. The light that is on says "Service Vehicle Soon". It is NOT the "Service Engine Soon". No "Oil Life" light is on, the oil was just changed at 4000 miles...a little bit over, but not too bad.

    I still do not understand what you mean by "rest the light."

    The tech at the dealership, turned the vehicle off, and waited a few seconds. Pumped the gas, after turning the key to get all the lights to come on without turning the engine over. He said that should have reset it.

    As soon as I put it in gear to drive away--it "Service Vehicle Soon" came back on again.

    Any advice??

If you replaced the rotors you may have the wrong rotors, or you may have dirty wheel sensors, it is easy to clean them with a tooth brush and brake clean, try this first. The reason is metal brake dust can collect on the sensor and stop the sensor from producing the 2.5 volts DC as it turns, this would be seen as a fault by the computer as a wheel not turning as fast as the rest of the wheels. Hope this helps if you need more information please let me know. And thanks for using fix-ya.

    um, the only light on is "service vehicle soon" the other lights went out with the repair of the front wheel hub. and it happened 1.5 days after the repair, during which time I drove errands all around town--thus my confusion. the diagnostic machine showed there were problems with the front wheel hub. so that's what they fixed.

    this could be as simple as a dirty air filter you need to take it back to the dealer and get it fixed at no cost to you.

ABS Light is on, and TRAC off Light on. MIDAS

Either someone damaged a sensor for the ABS/TRAC control, or the replacement parts are not compatible with the ABS system.

My abs,trac off and service vehicle soon lights came on.

You have an ABS issue that need to be addressed with a qualified repair facility.

ABS, TRAC OFF, and service vehicle soon light are all on. Mechanic put new wheel bearing and replaced wires that had been coroded. A week later the lights are all back on.

Sounds exactly like the problem I had on my 2003 grand am. I can almost guarantee you have a bad wheel bearing. The change in pressure on the bearing from turning causes the noise to change. The wheel speed sensor is also integrated into the wheel bearing hub assembly which is sending the signal to turn on your brake light.
I would change both front hub assemblies. Ran around $300 for me to do both and put them on myself. Its a very simple job to do yourself if you have the right tools. Make sure you have a "pulley puller" to pull the hub assembly off the CV shaft. You should be able to rent one from a local parts store like Autozone if you don't know someone that already has one.

Abs/trac off/service vehicle soon lights come on intermittent

its probably a wheel speed sensor or " " harness. if you replace your hub assembly it will take care of the problem. a new hub will run you between $100-$130. its an easy fix if you have a little mechanical knowledge. i dont know what labor would cost but if you know how to change your brakes you can figur it out.

Are you sure of the lights? If it is Service VEHICLE Soon, in addition to Trac Off and Anti Lock, it is most likely one of the four wheel hub assemblies. These are sealed bearing units that feed a signal to the computer for the ABS brakes and the tire pressure system. I had one go out intermittently (seemed to be aggrivated by humidity/moisture). I had it replaced, and another one is going out. It seems like they are a bit prone to failure. My Century has 101K, and I experienced the first one around 75K miles. Unfortunately, to tell which one is failing requires a scan tool above and beyond the simple one that most parts stores use. BTW, there was a problem that was fixed just prior to 2002 that was caused by the signal wires going to the left front wheel hub being worn through and shorting. I believe this problem was fixed by 2002.

Abs light, trac light, service engine soon light

The problem is probably the wheel hub bearings and it is more that likely the front. I had the same problem a few weeks on my 00 grand am gt. Connected the car to the tester it gave me a code for left front wheel bearing. I replace both wheel bearings because i figured what the hell they both have the same amount of miles on them. Taaadaaa no more lights!!! Hope this solves your problem.
