I noticed a few days ago the tach and speedo would jump once in a while when u would hit a bad bump in road and 2 days ago the abs light came on but didnt the next day is somthing shorted out or did somthing go bad Quote Link to comment https://www.bigmacktrucks.com/topic/35397-2000-e7-350-code-5-1/ Share on other sites More sharing options...
turckster Posted April 13, 2014 Share Posted April 13, 2014 I'd start with the most obvious, make sure all ground and positive connections are clean and tight. From the batteries to the starter, chassis grounds and cab grounds, ground relay. Also make sure your batteries are in good shape.
