Need Help, multiple module failure
Hey Everyone,
I have been battling with an electrical issue in my 2017 Super Duty Platinum Diesel. Been out of service for over 2 months now, has been to multiple mechanics including Ford dealerships and everyone is at a loss to pinpoint the problem.
Every module on the safety network randomly failures and loses communication with the Gateway module. I am on my 3rd gateway module in 3 weeks right now obviously that is not the issue. Will work for about 50 miles sometimes more sometimes less the wrench comes on with the ABS, hill decent, 4X4, adaptive steering, front cam, navigation, tractions control nothing on the tree works, airbags and more 11 total modules. Now the funny thing is not all of them always fail all the time. Sometime just the ABS and Navigation, sometime is it just the hill decent and traction control. Sometimes they all fail. We have checked all the connectors at the back of the truck and all of the recalls have been done. Sometimes when I restart the truck they all go off and it is ok for a little while sometimes they stay on.
I need some help please
I have attached a video of all the faults
Thanks in advance
RJ

I dont have the codes in front of me, I have to talk to the shop on Monday. they have checked every single pin at every connector on the whole network and all the wires seem in tack and operations as they should. I am thinking it is a alternator or battery. I have a monitor hooked up and running it now watching voltage. right now its at 14.7/.8 and all lights are issues are NOT present and everything is working fine.

I had similar issues and the reason was water intrusion into the main module in passenger foot well. Many contacts were in really bad shape. Three pins were corroded broken and had to be resoldered.
Your symptoms are definitely connection related. Pull all connectors and check them thoroughly.
The connectors in these new trucks are ridiculously small for cost reasons that they truly are a pain in the rear department

Currently I am on the 3rd gateway module in 3 weeks... I told the dealership it was not the issue BUT they insisted it was the issue and of-course it is NOT. I just had the brakes and hubs, done along with the ebrake a couple week before this all started happening so I will deff check that!
Thanks

Ive had those alerts all at the same time
at first I thought it was the big connector by the spare tire....cleaned it then dielectric greased it...but still had the alerts.
then I realized that the alerts started after I fluid filmed everything.....so I presure washered all the connectors and sensors (abs ) with a wide pressure nozzle.
problem solved
apparently the fluid film changes the capacitance of the cables around the abs sensors and then everything that uses the abs sensors goes hay wire.

interesting, I will deff check that out... I did the same went right to the connecters in the back but they were dry as a bone. I did just have the hubs, a speed sensor and brakes done a month before this all started happening.

that speed sensor would be my prime suspect.
