How can I fix my car?

So I went over the pass and had to put chains
on my tires for the first time. I drove not even
three miles before I had to pull over because
my check engine, ABS, low tire pressure,
traction control and electronic power steering
warning lights all came on! I am getting a
code of P2159 but does that explain my
electronic power steering? Could it be as
simple as maybe the chains got loose and
pulled something loose on the tire and I just
need to connect it? The car was in great
condition before this and no indication that
any of these problems would arise.
