Keffer inc Posted March 20, 2018 Share Posted March 20, 2018 on my way home last night, I got codes for my DEF pump or injector. Codes as follow: Spn 5394 fmi 5 (current below normal or open circuit /possible cause is DEF Doser or Doser pump assembly) Spn 5246 fmI 15. (Data valid but above normal values / no possible causes) So this morning I tried to keep coming home and the truck won't crank. (Key in on position, no gauges key in start, the gauges come on but no crank and then go out two seconds later). Is there something I can do to at least move the truck? My cell is 757-284-5306 thanks, andrew Quote Link to comment https://www.bigmacktrucks.com/topic/52859-2011-mack-cxu613-no-ignition-after-def-problems/ Share on other sites More sharing options...
Keffer inc Posted March 23, 2018 Author Share Posted March 23, 2018 The No Power when Key On was a fuse F7 was blown any causing that problem. Still diagnosis the codes though. I checked the wiring plugs, all are clean, cleaned the battery terminals and checked the 30amp that powers the DEF, it's good. Anyone know what to check next and how to?
