    Hello - My truck is having issues. I have attached the pics. There are 3 ACM codes (3216, 520372 & 5841). We tried to force regen it but it won’t.

    I would shut the truck off,turn the master switch off,then back on to see if the codes clear.If they don't clear then you have bad def, bad sensor ,or electrical wiring issue.

    No idea on that.You might need to hook it up to a computer to get it to regen.

    I am tried the manual regen, It wouldn’t let me. The nearest repair shop is 25 miles. I might have the driver start driving there. It is also not going 55MPH

    I would call the shop,see if they can come over to the truck.Probably cheaper than a tow.

    I do have DDDL. 520372 can only be cleared with DDDL. SCR closed loop at max. Good and bad news. First good. usually only need DDDL to fix. No tools or parts. Bad. You need DDDL to fix and it could take up to 3 hours.
