2016 Prostar w navistar motor codes

I just bought a 2016 International at auction it has the n13 motor and 600k miles on it. I brought some batteries out and drove it home, drove ok bobtail but felt lacking in power if I were to put a load behind it. The RPMs and speed weren't limited so I thought it wasn't in limp mode but I just bought a cheap scanner and pulled the codes and it seems there is in fact a torque derate.

Here are the codes

SPN 156 FMI 31
Engine protection torque derate
Condition exists

SPN 524 FMI 15
Aftertrestment SCR operator inducement severity
Data valid but above normal operating range, least severe level

SPN 436 FMI 4
Aftertreatment 1 SCR catalyst intake gas temperature
Voltage below normal or shorted to low source

SPN 322 FMI 10
Aftertreatment 1 outlet NOx
Abnormal rate of change

Then there is a body code I'm not worried about and I am curious what module this code is from SPN 655 FMI 14

My other question is if anyone knows of any common problem areas to check with the SCR system short of just replacing the whole thing. I am not the type to just start throwing parts at something.

 

Thanks Heavy, I was wondering about this scanner I thought the codes were supposed to be 4 digits. I think i will just go ahead and get an adapter for my laptop like a nexiq or something and try to find a copy of ned. Or a more generic software like jpro. (Edit: you say I can't use a generic scanner but I believe a full functioned diesel software like jpro may be able to clear hard codes?)

I was leaning towards replacing the sensors too but I saw a whole SCR unit on ebay with all the sensors attached to it for $1000 and was wondering what the chances were the actual SCR was bad.

Oh yeah and Merry Christmas guys thanks for the help.

 

Looking at pro's coverage page or looks like it will not reset Aftertreatment on the n13, only the older maxxforces, guess that leaves NED. I'm going to look into my options there

 

So it looks like I have a good running copy of NED, anyone recommend which cable/adapter to get? It looks like according to the manual NED works with nexiq usb link 2, noregon dla 2, and dpa 5. I have heard the drivers for nexiq can be troublesome so the Chinese clones are almost unusable. Haven't heard too much about the other adapters or their clones.
