I have found on two occasions that Carista has not done enough homework collecting data of fault codes and their actual meaning, though in both cases, the fault code retrieved by Carista was a valid manufacturer's code, ie the numerical number was correct, just the description was either wrong or not known.
So, if you have retrieved a code 922631, then either that is an error from the car, or ??? Pity you did not email yourself the actual report from Carista when connected to that car as it might have contained some extra info - I always, without exception do that - and from now on so should you.
