this is the thrird time this happened just wonderin ifu guys have had this problem i go to run the scr test o by the way 2015 thomas c2 6.7 allison trans hydro brakes i go to run the scr test and a window pops up saying let aftertreament system cool down now all three bus where cold only run for like a minute so i backed out of the test and it did it again had to try like 4 or 5 times before it word run finaaly they ran but on the last bus i workwd on i would not run the test keep sayin let aftertreatment cool down anyone run into this before????
I have had this happen to one of my C2's before. I tried several times, while cold, and it wouldn't let me. I checked for updates for Cummins Insite, found and performed updates, tried running test again afterwards and it let me run the test. I haven't had any issues since.
drop down menu ecm tests , the test just times how long it takes to get to operating temp., then its tests the nox efficiency and it looks at something else can't remember what though i use it to see nox into and nox out of the scr
