    I change it with used ECU , car no start and come up code B2799 , it mean the ECU doesn't match ID box , but I do smart code reset and smart code registration , it doesn't go though and also I do the ECU ID registration, it still doesn't start the car and come up the same code B2799 , anyone could give me some advise?

       I think all you need to do is jump pin 4 and 13 in the diagnostic connector then turn key on for 30 minutes then turn key off remove the jump. But first look thru the forum the info is somewhere. There is a you-tube video from a member of this community.

        I always use tech stream when performing this function in the order mentioned above, never tried it differently and never done it with an autel tool ,so have I no idea if our tool work for this specific function but its worth a try I think.  try jumping 4 and 13 of the dlc, that works in many cases after a pcm replacement as well. I will do it for 45 minutes instead of 30, worked best for me.
