Shallow Draft Posted November 2, 2015 Report Share Posted November 2, 2015 I had a message and codes spread. Also a no go until I cleared the codes. It said my transmission was out of calibration and the dreaded SM on the DIC. I cleared all the codes but forgot to write them down. It has not recocurred since and that was 1300 miles ago. Any ideas? Link to comment Share on other sites More sharing options...
hone eagle Posted November 2, 2015 Report Share Posted November 2, 2015 Had the SM 3 years ago driving home from Alberta ,when I got back i cleaned all the grounds and contacts of the batteries and it never reoccurred . Link to comment Share on other sites More sharing options...
Shallow Draft Posted November 2, 2015 Author Report Share Posted November 2, 2015 I will do that. Time to check the batteries, they are 8 years old and maybe getting near the end of their life. Link to comment Share on other sites More sharing options...
Jack Mayer Posted November 3, 2015 Report Share Posted November 3, 2015 Battery issues will do that. Grounds especially, as noted here and elsewhere. It is worth cleaning the battery connections, AND the connections to the starter and any shutoff or fuses you have. My battery isolation switch was pretty groddy and was causing hard starts. Make sure that the buss bar bridging between the batteries is in good shape as well. Not all of this relates to your trans issue, but worth doing yearly (or so). I just did mine because my Batteryminder trickle charger showed "bad battery" and would not complete a full charge (which it always does). A sure indication of a groddy connection OR a bad battery. Cleaning things got it back to a full charge and no faults on the charger. Link to comment Share on other sites More sharing options...
