I forget where I saw it, but if you hold in the Trip Odometer Reset Button, start the truck, and keep holding it till "TEST" appears in the display it displays a bunch of information.

I understand the Digital Tach (Which is pretty neat)..but when you toggle through what do all the other displays mean?

Any Help or insight is appreciated!

Thank You,
