    Fords K-17 versus K-20

    Is it just me or did some thing change here with 12.2. First had an 09 Ford Flex to diagnose, asked for the K-20 key, Thought this would be a CAN vehicle but ok. Then An 06 F150 with the 3 valve 5.4, again the K-20. Today I have an 11 Explorer and it still asks for the K-20 key for the PCM.. I thought the new Fords were CAN communication and in the case of the 06 F150 I could swear that in the past this vehicle used the K-17. Maybe I need a vacation and am just loosing it.

    You're not losing it. Although I don't know the reason why, the required key on those vehicles changed from K-17 to K-20.
    The first time I came across that I thought the same thing and reported it as a bug...but it isn't.
