This could be a number of things but the only way to know for sure is to get the codes that are part of that system. If you can't pull codes then just stop by a parts store as most of them pull them free of charge. Once we know the code we will have a better idea as to what the issue is and can start testing.

Here is a good video on this system if you are interested:

Let me know the codes and we can go from there. Thanks

I attached the information about this system. The fact that he found no codes is odd. As you can see in this description, the traction control light remaining on is indicating the system is disabled due to a DTC.

Were there any DTCs in the system? Any for the ABS system?
