Help - Dash Board Christmas tree-bad stuff???

[happywhencamping]

Went to take our GT 2015 out for a short weekend trip.
Started up, no issues, started to move from storage lot, lots of lights came on.
Turned off and restarted, no lights, started out again, when I was on the road, same thing happened. Turned around and went back to lot and parked.

Lights on

Wrench
Engine
Battery
Brake(brake was no engaged)
another light that means the brake boost is not working properly.

Manual says that the unit is limp home mode, electrical system has issues and the brake boost is not working(low fluid possible)

Also the engine temp gauge was showing no indication of being hot. It had been setting idling for a bit before starting out.

Does anyone have idea what the issue might be, or is there a common failure here?

I wonder if a serpentine belt went bad. AC did work as best it can.

I would take it to a dealer, but my local ford truck shop has stopped taking RVs.

Unit is under Ford warranty.

Take it to a Ford Dealer.
Sounds like the main computer had a failure.

Could be rodents had dinner on your wire harness. If so, insurance usually covers.

You might want to check your engine battery charge/connections, or alternator.
Don't know about these Fords but I have seen some Chevys that the computer gets power straight off the battery. Even though there was enough power to start the engine the dash would do strange things like idiot lights flashing, speedometer going up and down, ect
Just a thought

I recently had a similar problem with my 2011 Chev Silverado 2500 on a trip to North Carolina. Brought it to my mechanic and he found that the wire to the right rear wheel speed sensor, used for the traction control, had been severed while driving. Once it was severed I had 4 other idiot lights come on. Once the wire was repaired and he reset the ecm all was good.

Not specific to RV wiring harnesses,but we have exterior LED light strings on our rear patio. Worked great for past 2years,then one string went out. Turns out rodents had eaten some excess LED wire that was laid in a gutter. The gutter is covered with leaf shielding,so the varmits crawled up the down sprout and had uninterrupted snacks whenever they so desired.

Wiring looks okay, no rodents I can see
Battery terminals look okay.

I went to restart unit, battery is dead, used the emergency start to get it going. All normal, I did not attempt to drive it. Scan shows no codes.

Repeated several times, had to use the em start, got lights of various types to happen. Got a code for a throttle body report, engine was running rough.

Next time, no issues.

I did see batt voltage go from 9 to 6 very quickly.

My first pass is a bad battery plus another issue.

It is getting towed to a dealer.
