How To Fix Pro Power Onboard Fault on Gen 3 Raptors

[MedCityRaptor]

For all of you Gen 3 owners with the pro power that keep getting ground faults, I may have a solution for you. I was getting frustrated with my Ford dealer after taking it in 3 times for this. Each time they basically stated "wait for an OTA update" but it's been a year since I originally took it in for this. Every time it rained, snowed, or brought it through a carwash, this fault message came up. I am happy to say it has been over 3 weeks since I made this "repair" and I haven't received the message once and we have already had many days of rain and snow here in Minnesota. Above your driver's side exhaust tip is the connector for the pro power box in the bed. Remove the connector and blow it out really well with an air compressor to get any residual water out that may have made its way in to the plug. Add some dielectric grease to both sides of the connector. I also took a second preventative measure and wrapped the hell out of it in electrical tape. NO MORE GROUND FAULTS!

Nice job--I would instead of electrical tape I would use some Dual wall adhesive lined shrink tubing, that water cannot get into--eventually water will find its way into the electrical tape!! Something like these--pick one!!

SHRINK TUBING

I have a 2022 GEN three, it is equipped with the outlets inside the cab and inside the bed. However, it is not equipped with and pro power on board switch, button, of any kind to activate them. Can someone please help me with this problem? Thank you.

If you do not have a big inverter under drivers side rear seat and only have smaller inverter on passenger side, then you don’t have Power Pro. The receptacles you do have, even one in the bed should just work by plugging something into them. I’m assuming engine must be running.

I’ve been experiencing this same issue every time it rains. I’ll give this fix a try and hopefully that’ll take care of it. Thanks for posting!

Thanks @MedCityRaptor I hit a good bump on a rainy day and got this error. I knew it had to be a connector somewhere.

Thanks for this tip. I get the error anytime the roads wet or I’m in a car wash. Going to try this out
