3712 and 3714, truck is eating my lunch

[BreakOnThrough]

Big apology if I missed it, but I have searched before posting a new topic. Have a International DuraStar 4300. Cummins 6.7 ISB CM2350 B101 serial #73779980. Low mileage 70k

Truck Was derated to 5 mph because the DEF heater failed,and froze.Found the relay box above tank was full of corrosion and spread terminals, blue fuzz,etc. Replaced the Dosing pump and Harness/relay box from DEF tank to back of cylinder head, and and a new doser valve since it was original . DEF heater wouldn't heat up before repair, now it passes tests and original codes are repaired, but no matter how i try I cannot clear the 3712/3714 codes. Ran a manual regen with Insite. went into Advanced ECM Data and reset the aftertreatment log after reading that could be part of my problem. No dice.

When i try to run the SCR system test, it starts and aborts instantly with a " let exhaust cool down " window. Even on a cold engine. i also read somewhere that an ecm calibration will fix this issue. I have MR-HD PLUS PRO and MR-HD Plus Basic active licenses, but under service tab and related information I dont have the calibration option? Do I Need a different subscription?

I figured I was on my way when i repaired the BASE codes that resulted in the derate, only to find myself getting crushed. I am very new to Insite, and I am sure contributing to my mess. Any advice for a guy that is trying to learn this software? Have an open help request to cummins for info on subscription needed to update calibrations.

If anyone has run into the cool down pop up window on SCR TEST, that may be helpful as I understand if the truck passes the SCR test, the 3712/3714 will go INACTIVE? Then i could clear them. getting beat up over here . Thanks in advance!
