Electrical issues 04 Tahoe

well, you need a scan tool that does abs/ airbags etc cuz thats bcm stuff and even then it might not  do bcm data so unless you have access to a fairly high end scan tool such as Snap-on, tech2,etc you may have to pay to get it scanned.

as I've said many times here, codes DO NOT mean replace the part rather thats a starting point for diagnosing a problem flagged by the PCM/BCM. there are trouble shooting trees in the service manual and on Alldata etc that if followed will lead you to the problem. did you replace the correct 02 sensor? there are at least 3 on that vehicle

So a little update. After replacing that one burnt ground (I did go back in and fix it better so it has a good connection) as well as the battery to frame and block to firewall, im still having the same issues. I won't be messing with it anymore. I know when things are out of my league, so ill be having my mechanic chase this down. Thank you for all your help and advice.
