Trac is the control that doesnt let your tires spin when they are not making contact with the road. Just by having your emergency brake on will light up the trac light. It also come on with your abs. If you driving on a slick road and you jam on your brakes and the tires slide a little mine will say low track on my car.

trac off abs light , the problem is in one of the wheel bearing, that is where the sensor is.

Hello. The ABS [anti-lock brake system], traction control and service engine soon light are all interconnected. The ABS and traction control each depend on sensitive sensors to send a signal to your car's computer that there is a problem. The problem unfortunately is that the sensors themselves are bad. If your brakes still pump themselves when you stop fast, for example, then your ABS system is still working but one of your sensors is sending a signal anyways.
To check everything out you can take your car to many auto parts stores, or most recently AAMCO transmission stores, where they will scan your computer for free. Once the scan is done you will know exactly why the service engine soon light is on.
In the meantime, you do not need to worry about your brakes because all the ABS system does is pump them for you. You can still pump them yourself, like folks did for years before ABS came along. Same is true with the traction control. As long as you do not drive wrecklessly you need not worry.
So to summarize, call around to auto parts stores, or AAMCO to get a free scan. Once you have those results you can decide on how to proceed.

Have the ABS codes scanned. This will get you started in the right direction. Possibility is that one or more of the wheel speed sensors is not working or intermittent - could be wiring or connectors on these as well. Another possibility is the EBCM, Electronic Brake Control Module. I believe the EBCM will throw 1216 code in many cases. THese can be rebuilt online for about $150.00.
The more likely problem is the wheel speed sensors. THese are an integral part of the wheel hub. About $100.00 each for the part. About $250.00 each to have them replaced. They can be tested with an AC voltmeter by spinning the wheel. Also, they should read roughly 850 ohms resistance. The ABS codes will tell you which ones are not reporting.

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.

BAD WHEE BEARING AND PROBABLY THE PLAY FROM THE WHEEL BEARING HAS DAMAGED THE SPEED SENSOR FOR THE ABS
