How did you come across this code? I looked for it in the 2020 Service Manual. It shows a range of codes between U2200 and U23FF, in the table of DTCs. In column next to it, with a column header "diagnostic procedures" it simply says "Data Communications" with no further detail. Searching U2209, no diagnostic procedure is found.
