Mode 6 is self monitoring that the car's computer does to detect misfires. After the number of misfires exceed a pre-determined threshold the check engine light will be turned on. Mode 06 access looks at the misfires in a cylinder before the light comes on.
I had Ford IDS Power Balance Test and Mode 6 Data on the car performed today and found absolutely
(NO Misfires) of any kind and all is Good. Z
FYI for anyone interested its surely a great way to troubleshoot any underlying issues related to misfires and i'm sure your local friendly Ford Dealer can have this performed with an applicable Diagnostic fee.
