I finally got my car back from having the ground effects touched up. The fiberglass parts were cracking and there were a couple bites from speed bumps.
The Ross-Tech finally was connected and first pass was solid 0010 codes. Cleared and reran. Looked about the same. Cleared again and only two codes now
46 Central Conv 0010

75 Telematics 0010

I checked the thread on code reading. Still do not know which system these codes refer too.
Are these fault codes for equipment I may not have on this vehicle? The telematics sure sounds like it is phone related.
Plan on driving a bit later this week and performing another scan to see if any faults return.
Since replacing the TPM's have not seen a code. Plan on doing the brakes and rotors later this month. The pads look okay, the rotors have a lip at the edge.

Can you post that scan here.

After clearing all codes and driving it sporadically it was rescanned, now 4 codes. The door is known, sometimes the driver window will not roll up on first try. Takes 2 - 15 trys to get it movingf up. The parking is stange, seems to work.

I cleared codes twice. But never left the driveway.

75 is your OnStar backup battery
J529
G254 is self explanatory - likely corrosion/wire issue or dead sensor
Door could be a bad switch

Thanks, I am replacing the driver window controller today. Will clear codes to see what happened to the tilt sensor and the parking.

If they are broken, clearing the code won't make them fixed

You might check the wiring/power to the tilt sensor - it's under the rear seat.
Also check the anti-tilt switch on the door for corrosion, etc.

If you have the graphical display version of the park assist, it might aid in testing.

Many thanks, I will clear to see if they come right back. The parking sensor was fine 250 miles back. And at least on mine the signal is only audio. May be the issue.
Added pics, maybe they will appear this time.
