Go to C5 General and ask or do a search. I've seen some of those codes. The "TCS" I think refers to wheel speed sensors but the guys in C5 can clear it up for you. Good luck.

Here you go.
A1 RDCM = Right door control module
28 TCS = Traction control system
B0 RFA = Remote funtion actuation
I have no idea what they mean, but this is what they are.

These are problem codes from the DIC:

If you want the build codes, here you go:

Are any of the codes "Current" ( have a C after them)?
Or are they all "History" (have an H after them) ?

Would surely check out any C's.
Might also try clearing all the codes and see if any of them come back.
