Hello and welcome to JustAnswer!

If the traction control light is coming on while still and without pressing the button then it's because the ABS module is seeing an issue that will prevent proper traction control operation and has set a fault code. There are many possible causes including speed sensors, the hydraulic control unit or pump motor, the ABS module itself, or there may be an engine performance related issue turning it on if it comes on at the time the engine runs poorly.

The first step in diagnosing the problem is to use a scan tool or code reader to see what fault codes are setting. Do you know what codes are stored?
