Bests & Worsts Reviews from Amazon

I needed this to diagnose which wheel of my anti-lock brake system needed a hub replacement. All it told me is that I have a stored anti-lock brake fault, not which wheel it was. I had to go to my local auto part store and have their scanner tell me it is the left rear wheel sensor. I am not happy with the fact that it was not able to isolate the problem when clearly the fault code that was stored in the vehicle indicates which wheel sensor is faulty. The vehicle is a 2004 Pontiac Montana AWD.
