I recently received my new 2022 F250 SuperDuty XLT 4x4 truck with pro trailer backup assist. The purchase included the trailer camera and trailer TPMS kit, part number LC3Z-1A189-A which I have installed per the Ford instructions. The trailer camera works but the trailer TPMS does not.
When I start up the truck with the trailer power and 12 pin trailer cable attached, the truck software knows the trailer is connected and it goes thru the menu to configure the various trailer items but not the TPMS. Selecting trailer TPMS or trailer tire temperature gives the following message:

Trailer Tire Status Monitor Capability Not DetectedThe Ford manual says this means “The system cannot detect the trailer tire pressure monitoring system” (not much help). I get the same message if I leave the 12 pin trailer cable unplugged from the bumper connector. I’ve tried the following changes but nothing has made a difference or allowed me to get to the TPMS setup screen shown in the installation instructions.

1. I moved the TPMS RF receiver part number HC3T-1560-AA1 back as far as the cable would go so it’s only 3 feet away from the trailer tires. I did this because I’ve got Goodyear Endurance ST225/75R15 trailer tires with steel belts. The Ford instructions say to not use steel belted tires (really?) but lots of people have said their Ford TPMS works fine with them. If I could make it to the trailer TPMS setup screen, then I can see if the steel belts make a difference. Discount Tire installed the Ford TPMS valve stems and used their RF handheld tool to verify all 4 were transmitting.

2. I Added a second trailer in the menu because the Ford manual says this will reset the trailer TPMS. I set up the Pro trailer backup assist using the sticker for the first trailer and left it not set up for the second trailer but nothing made a difference.

3. I searched for a different wire harness under the truck near the back bumper/license plate in case I’m using the wrong one. The only other possible cable is not long enough to reach the back of the 12 pin bumper connector (see below).


4. A relearn tool was used on the trailer tire valve stems. I also tried letting the air out of the tires but neither of these things did anything because I need to get to the TPMS setup screen so it will watch for activity at the tire.

5. I thought I might have a defective kit so I borrowed a second trailer TPMS kit for testing. The new cable, new TPMS RF receiver, and new valve stems (activated with the relearn tool but not installed) made no difference.

6. I made sure my truck has the latest Sync3 software and FORScan shows the trailer TPMS is enabled (see below).


7. I’ve also used FORScan to look at the TRM – Trailer Module. It shows it is connected to the medium speed CAN bus. I can reset the TRM so it runs its self-test and it shows no errors. I’m a new FORScan user so let me know if there are other things I could look at.

The fact that the camera works tells me that I have correctly installed the 12 pin connector and wiring harness but just to make sure, I measured the voltages on the Truck 12 pin connector. I can see the power and ground pins, the camera video pins, and the TPMS CAN bus pins. These pin numbers match the connector pinout found on the web.

I also measured the TPMS signals on the 4 pin connector at the end of the cable that plugs into the TPMS RF receiver. It has power and ground plus the 2 CAN bus signals so it should be working if the truck software is configured correctly.


It sure seems to me like a software issue but I have zero faith that the Ford service department will have any idea how to debug this problem. If anyone has any thoughts or has solved this problem, please let me know.

 

Following. I have the TPMS kit (no camera), but haven’t fully installed it yet. I have only installed the new plug in the bumper and made those connections on the back side. My next step is to get the sensors installed in the tires. I’m a little worried about the steel belted tire issue, so hopefully it won’t be a problem. I’m not sure if my current trailer tires have steel belts, but I would eventually replace them with the Goodyear Endurance.

 

Maybe an obvious question, but, are the tpms sensors frequency-matched to your truck? They make several different ones. I had this issue once before, worth asking your dealer to check for you.

 

It's certainly worth asking the question. Thanks

 

Following….
I have a 2022 350, just installed the TPMS / backup camera kit (don’t need the camera) TPMS, comes up, truck lets me add and setup, no problems.
once trailer is disconnected, and then reconnected, TPMS will not pick up anymore….. driving me nuts!
Also, my truck came with the pro backup kit, which has the module, instead of the stickers, but module does not seem to work. I’m assuming the superdutys still do not work with the modules?? Found the stickers in the glove box, but they will not work with trailer setup (Propride)…..

 

I feel your pain. Your TPMS problem sounds different than mine since you were able to get to the menu to do the setup. When you say the "TPMS will not pick up anymore", do you mean the screen that shows the trailer tire pressure just gives dashes instead of psi numbers? Have you tried moving the TPMS receiver as close to the tires as possible to improve the RF reception? You're probably running steel belted trailer tires which apparently block some of the RF. The Ford directions say to mount the TPMS near the hitch but that seems too far away for a big trailer.
I'm not familiar with the Propride/Hensley hitch and how it affects Ford's Pro backup assist but I see some posts that discuss ways to improve visibility of the sticker using black tape. It would seem that using the Yaw backup box would eliminate the camera problems but I don't understand how this box is actually detected by the truck.
Maybe others on this forum know how this Yaw backup sensor works????

 

My Airstream Propane tank cover basically block any view of the trailer yoke beams. Also, where the ball sits, the numbers won’t allow the distance (I think question A ) to be input. The Ford menu seems to want a traditional ball hitch within about 12” of your tag. Mine is about 19” off……
As for the TPMS, yes… I just get the tick marks next to the PSI on the dash of the trailer menu….
mid I set up “new” it picks up the tire, let’s me go through the programming menu (let air out of tires until horn beeps) and set things up. Then even after re-airing the trailer tires to required PSI (seems you have to let out about 10 PSI when programming) things are all good. I even let the trailer stay hooked up with truck running for a few hours, but once you park and unplug your standard trailer plug and 12 pin plug, it never picks things back up once you hook the trailer back up….. I’m starting to think this is possibly a Ford software issue? Who knows with the world wide “chip” issue, how well software issues are working, plus this is sync 4, but menus still look just like sync 3….???
Also, seems like the F-150’s of 21 and 22 have updated menus, which also allow the Pro Backup module to work, but the Superdutys have not been updated….. on the F-150’s you can see all your trailer and towing info of the 12” main screen, but superdutys are still all just in the dash LCD….. frustrating….. and Local Ford service, basically has no idea that Trailer TPMS kit exist…..

 

It is my understanding the stickers have to be used for trailers. The module or yaw sensor part is for a 5rh wheel or gooseneck.....I don't think there is getting around the stickers for a trailer set up. I can't set mine up because my bike rack at the jack doesn't allow the sight for the sticker. Unless Ford had changed the system and I am not aware of it.

OP, I would see if the dealer can help, because it almost seems like the software isn't there! You shouldn't have to struggle that hard to get it to work!

 

Ford knows the stickers don't work. Since 2016? all the F150's with PTBA all use the yaw sensor - they did away with the stickers. I've gotten my sticker to work one time. The lighting has to be just right and it appears that full sun is not one of the lighting scenarios where it works. I've tried it on the a-frame; I've made an angle iron bracket and mounted it parallel to the tailgate on the tongue jack barrel; I've mounted it perpendicular to the tailgate on the tongue jack barrel; All at various heights and all verified that it can be seen by the camera.

If you have the yaw sensor, you will be light years ahead.

 

Did not realize I could use that on the travel trailer, I will have to check into it. Does the sensor have to be in a certain place?

 

The YAW sensors don’t seem to work on the superdutys…..?? F-150, no problem, but have not found that they work with the superdutys….. would love to know if someone with a 20-22 superduty has got the YAW module to work with no stickers

 

Did you find a solution? I took the next step forward today. Since I was skeptical that it would actually work, I took the spare tire from my boat to the tire shop and had them install the TPMS sensor. I then used this tire as a test tire. I went through the set up process and the truck recognized the tire sensor. For what’s it worth, I did this in my driveway without the boat. I just simulated the distance. I do have steel belted tires. So, this is a good sign. Next step is to have the tire shop install all the remaining sensors and do the complete setup process.

 

This is in reference to the yaw sensor. I have a 2021 SD and installed the yaw sensor, I added it as another trailer and set it up as fifth wheel. I only use it for backing up and have not used it often. I use the trailer setup while traveling, because the fifth wheel setting takes out your blind spot monitor.

 

I finally got it all set up on my boat. TPMS kit only. No camera. Despite the instructions saying not to use this system on steel carcass tires and to only use it on J Flange wheels, it works despite me having steel belts and not having J Flange wheels. So far so good anyway.

 

SUCCESS !
I gave up on West Hills in Bremerton and went to Gillis Ford in Shelton (my new dealer). They had my truck for a week and eventually figured it out with help from Ford's Techline. Their invoice says they updated the Gateway Module (GWM) and ran their configuration routine. Now I get the trailer TPMS setup menu as described in the TPMS kit instructions.
Searching "Ford truck Gateway Module" shows they've had some issues with F150's that needed new software but I couldn't find anything for F250's. It's also become apparent to me that just because your truck's Sync system says it has the latest software and is set up for automatic updates, don't believe it. The technician had to be told to update the GWM so it was apparently not obvious that the truck had an bad software build.
Hopefully this is the last truck problem I'll have for awhile (fingers crossed).
Cheers
