I purchased a new 2012 Impala LTZ - which is still in the family. We have not had the code you listed.

Here is a GM TSB regarding wiring issues with the 2012 Impala - which can cause a variety of issues: https://static.nhtsa.gov/odi/tsbs/2012/MC-10071203-3639.pdf

You stated that you looked over the harness, but I am posting this link in hopes it may help you (as it has instructions and pictures).

Good luck.
