My ABS light came on in my Western Star, it claims to have a WABCO ABS system in it. I was just wondering if there are any simple problems that occur, or if I should just take it into the shop. The only reason that I ask is that I can't stand it when "idiot" lights come on. Heck, I was looking to see if there was an easy way to unplug the light and go down the road. I am pretty sure that I don't need the system during the summer, and from what I understand it only affects the one corner that has the problem anyway.
