upsman Posted February 4 Share Posted February 4 Deleting was the first problem. Quote Link to comment Share on other sites More sharing options...
Onyx610 Posted February 5 Share Posted February 5 So the MID 144/PSID 40/FMI 4 is for “daytime running light relay short circuit to ground or open ground” not your issue…Now the MID 140/PPID 278/FMI 9 looks like it very well could be. It’s for “Missing Diesel Exhaust Fluid” 🤔 Quote Link to comment Share on other sites More sharing options...
Onyx610 Posted February 5 Share Posted February 5 (edited) Also your one time code of MID144/PSID230/FMI 5 is something to also look into. It’s for “software failure.” Which is “Incorrect/interruption of the program due to a power failure. There was no power for at least 10 seconds when the ignition is on. Breakage or partial damage to the power cord or ground of the vehicle control unit.” Edited February 5 by Onyx610 Quote Link to comment Share on other sites More sharing options...
