Unable to Charge PCS_a023

[42M3]

So I just had the PCS_a023 briefly flashed for like a second when I opened the passenger car door and the car was waking from sleep. It was so fast I couldn’t even read it. I had just got home so it wasn’t a sleep for very long. The car wasn’t even plugged in though is the strange thing. The notification quickly disappeared and is still in my alerts area. But I plugged in the car and it charged fine and the alert did not reappear. Has anyone else had this message pop up then disappear when waking from sleep?

If you Google PCS_a022 and PCS_a023, there’s a known firmware issue which is resulting in these particular error codes by themselves, even when not attempting to charge (have not seen reported on TMC).

One poster shared Tesla’s response… “This issue will be addressed with a future firmware update. No repairs are needed at this time.” Have seen several folks mention this showed up with 2023.32.

Thanks for the information. That really puts my mind at ease, was really worried as this is my first Tesla and it’s only months old. Thought it was strange to see that error when not even plugged in.

My Dad’s 3 month old model Y also has PCS_a023 errors this AM. He thinks it has to do with scheduled charging set while not plugged in. Definitely a bug.
