Service Mode/ disable ignition on shut off

[VBreithaupt]

I figured it out! To put your expedition in to engineer mode. While holding down OK button on left of steering wheel, push start button. Your accessory lights will come on, hold down until you see ET pop up next to battery symbol then let up on OK button. I assume this works for the 2018 up and to get out of it you hit the ignition button again to turn vehicle off. I don't know if it bypasses the shutoff timer. I'm testing it now. I will update when I find out.

Putting it in Engineer mode does disable the accessory time out feature. so if you are running your hot spot or radio for longer periods of time then here is your solution. Haven't seen a lot of threads on navigating the E.M. but it pulls up some cool things.
