Driver Screen Going Blank while driving

Tech working with Ford Engineering
Totally unresponsive while testing the modules. Then restarted the vehicle and everything started working again.
They believe a wiring harness/module type issue. But trying to recreate it while driving to pinpoint which module prior to taking everything apart.
Not sure how long it will take, no loaners available.

That really sucks. I would bust balls to get a vehicle. If they are out of loaners tell them you need a rental. I saw a post in here the other day from someone that mentioned a specific harness connection was found to be a problem in their truck.

Another member mentioned that his seats and console had to be removed because they found a wire harness had come loose, but his screen didn't go blank, it had multiple display errors.

From my post on f150 board
2021 Ford Raptor
IPC cluster keeps resetting
Only has 800 miles
Has been happening since new
Seems mostly random times even though today it did happen as I went over a bump
Sometimes it will reset for as long as 10 minutes
IF the IPC is showing black the AC controls and such also do not work and do not have power
Sometimes shorter resets are almost immediate.
Throws Service Light soon and shows errors
Service vehicle soon
Check 4x4
Check locking differential
Throwing CEL on longer resets for
Powertrain Malfunction/Reduced Power detected a powertrain or a four wheel drive fault
Malfunction Indicator Lamp Regulatory All Terrain Control Module
Malfunction Indicator Lamp Regulatory Fuel Level Sensor
Malfunction Indicator Lamp Regulatory Fuel Level signal indicating a value over full
Malfunction Indicator Lamp Regulatory Lost communication with dash front control interface module
Malfunction Indicator Lamp Regulatory Powertrain control module lost communication with instrument panel cluster for period of time.
Malfunction indicator Lamp Regulatory Powertrain control Module lost communication with the heater ventilation air conditioner module for a period of time.

I think you should read that other members issue, sounds like some of the same.

Found the other thread, see what you and your mechanic think of this:

Got a series of random faults on start-up

Got the following faults on a start-up this evening all at once: Powertain Malfunction / Reduced Power, Restraints Indicator Lamp Warning, Hill Start Assist Warning, Pre-Collision Assist Not Available, and Blind Spot Detection with Cross-Traffic. Shut it down and did a re-start, but they did...

Nothing but headaches from the dealers service department.

They found a loose ground in the instrument cluster. The tech found out it would reset everytime you hit the dash above the ICP. Seems to be working properly now.
