Got an ABS light on. Previously, I cured it by reseating the plugs
behind each rear wheel, and under the front hood.It was OK after that
for almost 2 years. The ABS light came on again. I reseated
everything,I think, but the light won't go out. That means no ABS. Has
anyone troubleshooted this kind of issues themselves with success? Any
other useful ideas to correct this, besides taking it in for repairs?

Thanks.
