^ I have two, one I loan out to friends when needed for a small fee, and my personal one (which can read ABS, the other can't
). Invest in one if you plan on owning a vehicle. They're reasonably priced.
Stop by Auto Zone, Advanced, etc. and get them to read the code for you in the mean time. It's free, and they'll give you a brief description of the problem as reported by the computer. Then, go home and google it. Chances are, there's a solution
somewhere on there (ahem, cough cough, not naming sites).
