Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

In most cases the ABS as well as the VSC lights come on when the system sees a fault and when this happens the computer will set and store a fault code and or codes. In order to get some idea as to what is causing the problem you are having you are going to need to start with having the system scanned and the fault code and or codes retrieved that should be setting while the problem is occurring. If you can get this done and post back with the results I will see if I can help you determine the cause.
