Hi ! I have Toyota Highlander 2006.Till now
everything was running smoothly. Lately check
engine, trac off, and vsc light went on. My
husband reset those and code 1600 came out.
After a few weeks lights came on again.What is
that. By the way my brakes make a weird noise,like
a whistle, but my front drums are really smooth, so
it's not a brake pads problem. What that can be?
