Engine Controls and Fuel DTCP159F or P15A0
Fuel Economy Mode Switch Circuit LOW or HIGH Voltage 159F is Low voltage
Center Console Switch ( Weather, ECO, Tour, etc) wire voltage is too low.
Seems to say the Multifunction Switch is going bad.

The 2 switches on the lower dash, to the left of the steering column are currently not plugged in. Would it have anything to do with that?

Um.... Seems to ask the question of "Why are they disconnected?" One is alarm related and the other is the rear hatch (I think)???

It temporarily disables part of the alarm system (Intrusion and Inclination Sensors Disable Switch. I think).

Was removing a shifter the other day and turned on accessory mode with some cables disconnected under the console, including mode switch. Think I got this code and others. Put everything together and cleared them with scan tool and then gone. Freaked me out at first. ; )

That's what I figured so I wasn't all that worried.
Just put on a supercharger so theyl clear the codes when I bring it in for a tune.
