My VSC, ABS and VSC OFF lights are on. I also have a pulsing Brake pedal when I hit the brakes. I know what the issue is with the pulsing brake could be but I'm wondering if the ABS error could have something to do with it. How do I diagnose the light errors?

 

Going to need to borrow or obtain a scan tool... Many parts places will have a generic one that will at least pull engine codes. Start there, as many VSC / ABS lights are due to check engine light fault codes.

 

Had one of those scan tool's. Nothing came up. It just said no codes to read

 

Sounds like a broken tone ring on one the axles.

 

Is that the ring that the speed sensor uses to determine speed?

 

Yes it is, I'd also check for build up on the end of your speed sensors.
