Action required/service messages

Hey guys, just thought I’d see if anyone here has any idea of what could be wrong before I go to the dealership and pay an arm and a leg to get it fixed. So I have 2014 Silverado 1500 5.3l and it was in a collision back in January, had to replace the frame (at home) and ever since then I’ve had messages on the dash for stabilitrack, 4wd, steering assist is reduced, and the lane departure warning doesn’t work and neither does the park assist. My 4wd still works though. I checked every ground connection and checked every fuse and can’t put a finger on it and can only think it’s a computer problem or something along those lines

A scan tool is probably the only way to read all those modules to see where the fault is.

If you take it to a dealer or any other shop, do yourself and the tech a favor and tell them the whole history.
