Pontiac Problems? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to help with this today.
These lights will come on when a fault is detected with the traction control system.In most cases this can be a wheel speed sensor that is sending an incorrect signal causing this here needing replaced.This disables anti lock brakes when these lights are on but you will still have normal power brakes.The vehicle can be driven like this but it is best to have the fault codes checked with a scan tool that can plug in and communicate with the anti lock brake computer as well as engine computer to see what codes are set.Once this is done any codes set need diagnosed to locate and correct this fault.In allot of cases the scan tool is left connected to the vehicle and the vehicle driven to then use the scan tool to view the wheel speed sensor signal data to check and see which sensor is sending an incorrect signal as this is the sensor needing replaced.The only time these come on like this here is when a fault has been detected needing diagnosed and repaired.
