RE: CM 871 won’t regen
I completed the trouble shooting in Insite. It ends at replace harness if that doesn’t fix it replace ECM. The harness is a month out so I installed the ECM and it didn’t change. Fails the heater test every time. I did my own harness testing looking for shorts to power, ground and resistance and really don’t see anything wrong with the harness. I’m think about installing new heaters thinking they may fail when power goes to them even though they pass the ohms tests. Any info would be appreciated!!! Cummins tech support literally laughed at me when I asked for operating peramiters of the system. Thanks TIO
