    All I could dig up woth a quick google is that the first code means that there is no data recieved to the switch field unit.
    check fuses behind glove box to start with, do a little research about the SFU and see if you can find more on it

    Apparently the second poster must have had piggybacked onto this old thread with codes of his own.

    I would not know how to reply to this. It will only confuse the situation even though it is not too difficult to google codes in general.
