Gateway Module communication problem

[MichaelJones810]

F150 Powerboost 2022 VIN is 1FTFW1EDXNFB58800

My ford dealer was doing a couple minor recall repairs and they notified me that they are unable to communicate with the gateway module. They said that they are going to have to pull the dash and check for any wiring problems to the module but they won't get to it for several days. I went ahead and brought the truck home and will take it back to them in a couple days. When I got it home I allowed all of the pending OTA updates to run and everything seems to be working fine. Is there any test that I can run to verify that there is still in fact a problem communicating with the gateway? I have a Mongoose connector and a Forscan license. I can also buy a 2 day fdrs license if necessary. Can I test the gateway communication with Forscan?

If dealer is going to mess with it under warranty let them to it.

Does Forscan show any trouble codes?

I'm not sure if Forscan will show it working or not the way FDRS does (gray, red, green, purple).

You can delete profile in Forscan and when you connect see if gateway shows up when it is finding modules. It could have an issue though, and would need FDRS to see that.

The GWM shows up when finding modules. I don't see any trouble codes listed, but I'm not sure if I need to look somewhere other than the module listing to see any trouble codes.

I was able to pull the configuration data for the module and view that. Would that mean that I'm successfully communicating with the GWM?

I think the dealer suggested there was a problem because I was getting a "Trailer Brake Controller Module Fault" message and the dealer said that they could not pull any codes.

As you suggested, I'll probably just take it back to the dealer and let them check it out while it is under warranty. I just hate for them to tear into it if there's not a problem. Thanks for your help.

There are some SSM for trailer brake controller issues so they might be checking some wiring and other things to correct it. I hate dealer service, but if in 36k warranty I'd let them handle it.

There is TSB to update the GWM module for the trailer brake fault error message. I had this done 2 months ago and the error message never came back. Before the the GWM module update the DTCs show the trailer brake was losing communication intermittently with the GWM module..

The dealer is telling me that there is still a problem with the GWM. I have only been able to talk to the service desk and not an actual technician, so I can't get a detailed description of the problem. They are just telling me that they can't "get past the gateway module to the other modules" and this prevents them from getting any codes. They have replaced the gateway module and it made no difference. The truck has been in the shop for 4 weeks and now they say that they are waiting on Ford Engineering to help. There is no discernible problem with the truck for the user, but I am hesitant to just go get it if they claim there is a problem that could affect repair later on. All of the ota updates ran fine. Any advice would be much appreciated. I fear Ford Engineering will not be able to help.

Only thing I can think of is your VIN isn't releasing the update for GWM. That is definitely a Ford engineering issue that is causing problems for lots of owners on here that fell behind on updates end of last year. Nothing critical being missed, but it is annoying. If your truck is one of those then they cannot do what they need to do to fix it until Ford fixes it.

If your truck is drivable they should release it back to you and you get called back in later for it. That is just my opinion. No reason to have it sit around and wait forever.

No way would I let the dealership touch my truck, especially disassemble my dash, if FDRS can perform updates and/or communicate with the GWM.

A malfunctioning GWM would be fairly obvious since it plays a significant role in communications across the various busses between modules.

Unless I'm missing something, I'm sceptical that you have a bad GWM.

Agreed! with @Snakebitten Don't let the dealer butcher your dash to do exploration. There has to be a valid reason as to why they say it not working. It's the main hub to every module in the truck. If something isn't right it would be throwing a lot of DTC's. Are there any associated reported DTC's? The is receiving OTA's, is Fordpass working?
The gateway is like a home internet router, it talks to every module internally. And receives data through 2 external sources. Those sources are the ODB port for FDRS and the TCU module to handle cellular activity, Fordpass and OTA updates. You should message rugedraw and have him check your truck for problems in PTS, he can give you a list of all DTC's reported by the truck for the last 90 days and also check if there are any configuration and communication errors.

I did in fact turn off automatic updates last year and avoided updates since then. Maybe that's the source of the problem. I'll give them a week to see if Ford Engineering responds and then probably just ask them to put the dash back together and pick it up until they are ready with an actual fix. The dealer offered to do this, but I didn't want to slow things down. Is there usually a big delay getting a response from Ford?

I'm sure you're right. I felt that replacing the GWM was a waste because I can't imagine how everything could be working of the GWM was bad. I connected to the GWM with Forscan and a Mongoose connector. I hope nothing was damaged replacing it.

It received and successfully installed all OTAs and Fordpass is connecting to it fine. It is not showing any reported DTCs, but the dealer is saying that is because the GWM can't get the codes from the other modules. I don't think things would be working fine, like the power tailgate, if the GWM wasn't communicating with the other modules. Is "rugedraw" the actual full user name of the forum member that might be able to look up any DTCs for me? I listed my VIN at the start of the thread. Thanks.

Yes, @rugedraw is the guy you would want to have look at your truck, he may be able to shed some light on your situation.

I got your message, but figured I'd respond here. I see they replaced the GWM and seem to have PMI'd it correctly. The truck has not reported any codes that show there are any issues. Without being able to plug into FDRS, I can't see what they're seeing. The only thing I see that is abnormal is in the column to the far right below. They did a network scan with FDRS as recent as two days ago. That forces a sync of all modules with the server. However, as you can see, many modules have not reported themselves to the server on a consistent basis......some dating back to last year.

For comparison purposes, here is my truck that was scanned with FDRS recently. As you can see, the dates are more consistent between when the modules reported themselves. So, it seems like maybe something is wrong, but I can't tell what it is.

This may be a Jesse question more than me. If you have a Mongoose and FDRS and the issue is software related, I am sure Jesse can figure it out.
