Macktruck1 Posted December 12, 2022 Share Posted December 12, 2022 I’m getting an inactive communication code of mid130 psid204 fmi8. When driving the truck it cuts throttle and boost, and the rpm hold steady at 1k. The issues comes and goes every so often sometimes 10 minutes, 30 minutes etc. No active codes just one inactive. No one can seem to tell me how they’ve fixed this issue in the past. Is it a wiring harness, exciter ring, ribbon wire harness? Anything will help so I’m not throwing unnecessary money at this issue. I have video of the issue but it won’t let me load it here. PLEASE HELP!!

Freightrain Posted December 22, 2022 Share Posted December 22, 2022 Easiest way to post a video is use Youtube and paste a link. This forum does not handle large downloaded video files easily.
