| run any test or drive it, what does the outlet nox ppm state (if you have JPRO jut click on the SCR pic it will give you ppm)compare it to inlet nox ppm reading if outlet is way off(not dropping or raising ppm ) it will think the SCR is missing and not changing the ppm from inlet to outlet and also give an eff. code , the ecm is seeing everything is working just can't pick out the faulty part (ecm sees the right temperatures and see that def is being dosed so why is the ppm not dropping stuck in range outlet nox sensor |

| from a quick search perform a regen or let idle(not fast idle) for 5 min. what does condition for clearing code state, the ecm must have to see everything working like it should , or maybe OBDII and it needs four drive cycles to clear |

| classic C2 harness failing, or a PDM with bad(green)connections on the underside maybe 3714 was on due to the def level reading, I eplaced a header on a 2014 C2 and it worked for a day and now it reads full all the time, never looked into it driver just adds def when he fuels. |

no way to get calibrations unless you can find someone that can download then email them to you.
what is your calibration and ESN at now i can check and try to send you it, getting it into to your INSITE and being able to do it is the other question
ok found instructions for you , with the ESN i'll need an email to send the calibration to

that ESN comes up as a DT90002 calibration not a DT90373 on quickserve and the latest for that calibration that does anything would be DT90002.37 but if this is what Insite states when hooked up to it I can get that too, you won't be able to change the cali without zap its or not sure what this is called now
That email that is on my account I can access when I get home already forwarded the cali to it if you sent your email to it |

| DT90373.10 is the highest calibration in this package no other updates I'll email it to you , pretty sure you just extract the file to the calibration workspace then from there you can access it by updating the ECM |
