Id have to know what code has triggered the Service Engine Soon light in order to diagnose that. It could be related to the anti-lock and traction control system being off or it could be something separate.

That said, it is common for the anti-lock and traction control to be turned off if one or more of the wheel speed sensors goes bad. In some cases the wheel speed sensors are separate from the wheel bearings but in your case I believe they are integrated with the wheel bearing, so in order to replace the sensor you have to replace the wheel bearing.

In order to know which wheel bearing is the culprit, you'd have to have the car hooked up to a scan tool capable of reading ABS codes.

I had the same problem in my 01 Alero. I took off both front wheels and there was corrosion on the electronic connectors. Once i cleaned off the corrosion and put everything back together it fixed the problem, and no more lights.

There should be a switch near the gear shifter where you can turn the traction on or off

SOURCE: I have an 2001 oldsmobile

you have a problem known to many alero and pontiac grand am cars you have a bad wheel bearing,this is a common problem with these cars and they will not do a recall on this.you need to have your front wheel bearing hubassemblies replaced its not a bad job can be done by a decent backyard mechanic but a lot cheaper then going to the dealer, just save your reciepts in case they do recall your car for this problem they will reimburse you for your cost. If you have service engine light on, trac. off light and the ABS light on the same time, you may be able to get it fixed my reprogramming the power control module (with updated software calibration).

SOURCE: service vehical soon anti lock and trac off comes

The computer system reset every time you turn key off. The system then does a 3 second bulb check to verify all is functioning correctly. If all is well stays off. The reason why it only turns on when moving is because the abs sensors are either not picking up any vehicle speed from one of the wheels or there is a faulty connection in wiring at one of the wheels. Need to have vehicle scanned by a good shop and verify which wheel is causing the problem. If light is on ABS and traction control systems are disabled.

I have a 2004 Oldsmobile Aleroand I would like to know what needs to be done to fix the service vehicle soon anti-lock and trac off light from coming on


First you'll need to take it someplace to get the computer checked for trouble codes. The codes will tell you or a mechanic what to test.
If the check engine light comes on, it will also turn on the other warning lights even if there is no problem with trac or ABS.

Anti lock light and so on , is on


Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the Check Engine, Service Engine Soon, ABS Or TC lights to tell you that there is a problem and you should have the car diagnosed and repaired. I would take it to a service center you trust and let then come up with a solution. Sometimes a problem in one system will turn light on for other systems that communicate with it, but it doesn't mean there is a problem in all of the systems.

Service engine anti lock and trac light


This is related to a problem in the BODY CONTROL MODULE, the GM dealer can test this module and give you some idea of the repair cost, this is a common problem on all newer GM cars.

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.
