2014 Mack LEU613 came in with active codes P100000, P208E00, P110386. Removed def doser to test and found hardened def build up in pipe. Cleaned out pipe. replaced def doser and the P208E00 became inactive. Performed a scr crystal sublimation test and P100000 & P110386 were still active. I have tried several different test and procedures to clear out code and nothing has worked. Any ideas?

Still struggling to repair this SCR issue if anyone has any ideas. I have even gone as far as reprogramming the ecm and acm. Same active codes are still there.

The dealerships have access to CBR  “ Case Based Reasoning “ .  They can type the VIN in and the fault code and it comes back with the latest fixes for the fault. This newest info is not usually put into PTT Tech Tool until a big update is done . We check for PTT updates daily. See if your local dealer can run the fault code numbers in CBR.

I used this a couple months ago on a Volvo L180H. Was awesome. Machine has a Groeneveld grease system on it that was faulting(actually not). Fault code on machine was blaming the vendors greaser unit for system failure. In fact it was the machine side grease pressure sensor causing the trouble. Volvo engineered the machine software to automatically blame the Groeneveld unit if it’s machine side sensor saw low pressure at the lube rail. Ran the CBR with active code....shop in Denmark had listed the solution this last March. Poor devils had replaced thousands of dollars in parts to find the problem. It wasn’t the vendor greaser, it was the machine side rail pressure sensor failed, but then blaming the vendor greaser via fault code.

If my machine sees a low pressure reading it must be the other engineers junky greaser. Seems like good'ol fashion arrogant logic? The guy writing the software gets to pick and choose.
