PO59F-U1511 codes

[16Escalade32]

So I had a PO59F code for active air shudders, I replaced them and cleared the code. Next day U1511 comes in which I believe is associated with the shudders as well? They work as they should, I’ve double checked the harnesses. Does anyone have any ideas?

thats a communicaton error, check the harness, may not even be associated with the shutters

What vehicle are you working on?

Does your scanner show the 2-digit suffix of the code? -01, -02, -31 or the like?
