2012 Freightliner Cascadia Code CA8 33 & ABS light on

You sure thats not 'CAB 33' ?

As for the ABS llight, check for missing/damaged cables on each of the wheels since a blow out is a pretty violent event.

 

CAB 33 is a general cabin SAM fault, you need to get a more specific message by pushing the square button next to the display while the truck is stopped. It will go from daig to fault, it was hit or miss when I had a fault on mine, as to whether I could get it to display the specific fault code.

 

I think if he holds the button down while fault is displayed, then it will display the specific fault.

 

I don't think the message on his display has anything to do with the ABS though. Which is what I would be more worried about.

 

This youtube video shows how to get to the specific fault:

 

I had tire chains break and cut the ABS wire. I was able to just splice it with wire crimpers and tape. It would work for a year and I had to do it again. After four years I traded off the truck, never did replace that wire, just kept patching it.
So yours is probably cut from the tire. Try patching it first, if that works then you'll know and can replace the wire at your convenience. Assuming there is enough wire left to fix.
