Hi there,

 

Welcome to justanswer.

 

This indicates a fault with your traction control system. This is typically caused by a faulty wheel speed sensor (about $100usd), but in a worst case scenario, could be a failed traction control unit. You will need to have the fault codes read from the car in order to determine which wheel sensor has failed, or if it is perhaps the moudle itself that has failed.

 

Please let me know if you have further questions. If satisfied with my assistance, please press ACCEPT so that I am compensated for my time, effort and expertise. I am not compensated until you press accept. None of the deposit you have paid will be transferred until you press ACCEPT.

 

Cheers,

 

Steve
