I just read the codes out of my truck and they are as follows. c0040 and c0201. Can anyone tell me what they mean .thanks. fattkidd

Try this website DTC Code Look-up (http://www.autotap.com/codes.asp)

Looks like C0040 is loss of communication with brake module

C0040 is right front wheel speed sensor circuit malfunction

I found those on a forum search
