Will your scanner show you your steering angle live data?
Also what errors related to abs do you get when that comes on?
If ABS light comes on/off suggestsb your SAS is intermittent fault and clears some of the time.
The TC error says communication problem from what a brief search shows so i would use some deoxit gold on the connectors both sides you can try wd-40 or contact cleaner spray.
Definitely check the TCM / EGS connector in the ebox and confirm all pins and pin sockets are in place correctly.
Very recently a similar error turned out to be a pushed in pin socket in the ebox.

Hi
So, i took your advice and disconnected the TCM and sprayed contact cleaner and then after drying the connector it was reconnected.
What i am noticing the most is the intermittant problem of the waring light and ABS light coming on when it feels like. But ONLY happens when i start the car. It is like you turn the key and wait... hold you breath to see what lights you will have with you today lol
I used two code readers to read the codes on my car. The first one was a bluetooth device connected to my OBD port and read on an app installed on my phone.
These are the results...
