2012 freightliner cascadia DD15

Hey guys not quite sure if this is the correct forum, but I can use your expertise if possible. I have the following codes and I cannot seem to find the right information so I came here.

1) Chs 71 spn 524049 fail 31

2) cab 33 spn 524049 fail 31

3) eng 0 59.6 fail 13

4) eng 0 60.2 fail 13

5) eng 0 60.0 fail 13

6) eng 0 97.3 fail 13

My symptoms that I'm experiencing, truck shuts off and on like crazy. I don't have any lights at all. So I'm thinking something electrical? Once again, wasn't sure where to go so I decided to choose this forum. I hope to hear from someone soon. Thanks!

 

Battery switch meaning kill switch?
