Sounds like a bad speed sensor, have the codes read.

Its most likely a bad ABS (anti-lock brake system) speed sensor. ABS pump or modulator assembly. When the light is on, your vehicle does not have the benefit of the ABS and traction control features.

Ice is a big problem. There is very little traction to be had and managed. It is likely that the system is working, but in icy conditions you simply need to be VERY gentle on the gas pedal. The heavier the car the bigger the problem. Traction control systems will work well in wet or even in snowy conditions, but if you are gunning the engine on ice, nothing will help. You will be out of control.

No, your check trac light is used to monitor the traction control system. It is sensing an issue in the traction control system, which is pretty complex. There may be a code saved in the computer that a dealer could pull for you.

Its your traction control, means your traction assist is not working or is turned off

The Enhanced Traction System (ETS) is designed to limit wheel slip during acceleration. This objective is accomplished by cutting fuel to selected cylinders, retarding spark and upshifting the transmission. The EBCM monitors wheel speed slip through the ABS wheel speed sensors and determines the desired torque reduction needed to minimize wheel spin.
the wheel speed sensor may be bad

If you have a switch for the traction control, the stalling of the engine can be reduced or eliminated by turning off the traction control.

The traction control probably has debris inside the rear emergency brakes. The traction control works by counting the speed of each wheel. When the part that counts the speed is blocked with debris, it thinks one wheel is slipping and kills the engine and applies the rear brake to the fastest spinning side.

The motor is suppose to lose rpm until the wheelspin is stopped. Then the motor is suppose to run normally. If the motor is completely dying you have a terrible problem with the sensor on the rear wheels.

The Traction control needs to be looked at, some Brake shops may be able to fix it. A dealer would have the tools. There should be nothing wrong with the engine, its suppose to react to the sensors.

sounds like the brake pads may be metal to metal, that could be the noise problem, but until u have the system tested for the trouble code that is setin the ABS modules memory when the light comes on you are guessing, the Dealer is the only one in most cases that has the scan tool to check ABS trouble codes.

Your traction control comes on when it notices either your rear tires slipping or front tires slipping and it counteracts the slip to control the slide. It should be working all 4 brakes though not just the front. There is a traction control sending unit under the dash that should be looked at to make sure that it is sending the Trac Control the right message. If it is reading the slide wrong then it should be replaced. Sometimes then can just reset the computer and all works well other times you need to replace the sensor. I would see if they can reset the computer first then go from there. Pleae rate if satisfied. Thank you
