Found the Engineering test mode

Press the setup and reset keys together with the ignition off and then turn the ignition to the on position while continuing to hold the buttons.

And this gets us the ability to do what?

It displays more options on the dash menus. It’s not like this was a secret....

Well, I didn't know about it. I'll have to check this out. Thanks

I guess some of us are engineers...and others...well...not.

What’s that supposed to mean?

In my opinion..this mode is good for nothing in diagnostics..it wont show you any important DTC like forscan do..
Maybe a half of MS-Can DTC's or less

So..what is it good for?

On Mine I only neeD to hold down RESET before turning on ignition.

I use it sometimes when towing my camper so I can see a digital display of engine temperature, been doing it since 2006 because I already knew about it from the 2005 F450 we had at work back then

does anyone know of a way to enter engineering mode while vehicle is already running? Also any way to change Celsius to Fahrenheit on coolant temperature?
