Just click on the radio button that reads "Click for Diagnosis".

They actually put a disclaimer at the bottom.

 

HA! I saw that a week ago or so. Too funny.

 

Amazing! First click was actually my problem.

 

now I know how my dealer finds problems!

 

LMAO Steve
thats how Ford got the bad name for 6.0. using the magic black ball.
lets change HG, or noooooo lets tell the cust that he was running bad fuel, and he needs new engine LMAO....

 

I've got to get one of those to fut next to my EASY button

 

I bet it's true too.
You take your truck into the shop and if your truck isn't fixed one the first diagnosis they're just going to try something else, in this case shake that 8 ball another time around.
too funny not to be true.
