6.0 psd p683 code
Hello Folks,
I'm getting an intermittent P-683 (Glow Plug Control Module to PCM Communication Circuit Code). I clear it and with in a few days it returns. It usually does not set the Service Engine Light. While there are a host of things things mentioned in the trouble shooting article it seems that these engines have a quite a few "common" weak points that cause issues. While probably obscure does anyone have any personal expertise with this particular code? Thanks in advance!
