Got my TPMS trailer setup and working for me

[nkyhunter]

Today after 1-2 years of reading and software updates from ford using FDRS it works!!! Have this installed on my car hauler that I use for my Polaris Utv.

That is a nice addition. Is it only available for Lariat and above? Do you need FDRS to make it happen? Is this a Ford TPMS ? Or is it 3rd party?

I have a tremor and software was there in truck just not updated, do I used ford diagnostic repair software (FDRS) and also with the help of the trailer kit/tpms , if you can select tow in the display of the dash then you have the software, I'm guessing you don't?If not then you would have to update the software and also get the rear end harness for the truck to hook up to the 7 way

Replacing the rear harness and doing some updates with FDRS and edits with FORScan, I successfully enabled a wired camera and TPMS in my '21 Job 1 XLT, as you did. I do not show temps, only PSI. Can you list the FORScan changes you made? I'm hoping I can get temps, too. Through research elsewhere I have determined that temp display is a function of the truck, not the sensor or receiver.

Your Tremor has a digital instrument panel display, where my XLT is analog. That difference may prevent my seeing temps but I want to compare your changes to make sure I've done the same.

I didn't use Forscan I used (FDRS) Ford Diagnostic Repair Software, I used the SW tab and found the trailer software and downloaded it and ran it, other than that not sure what forscan has to show what to select? I have used Forscan since my 19 f250 which I sold in 21.

Forget FDRS. Is there a Ford TPMS trailer kit that works with our trailer technology package?

Can you elaborate on what that trailer software is, or does?

Perhaps but I don't know what the trailer technology package includes.

It is essential that you have a 12-pin connector on the back bumper under the 7-pin connector, and that you have more than 2 conductors feeding into the rear of the 12-pin connector. If you do have the connector but have only 2 conductors, you have to replace that wiring harness. If you don't have a 12-pin connector but there is a plug for it stubbed out from the related wiring harness, it may still work.

I replaced the harness on my '21 XLT that has Co-Pilot 360 Assist 2.0 with part number ML3Z-13A576-PK, as described here and in other threads. That enabled me to install a camera/TPMS kit I bought on ebay for $300. (That's an unusually low price.) The trailer camera requires having 360 cameras in your truck. My camera/TPMS kit also accommodates the yaw sensor (for pro backup) that came with my '21 XLT.

If your truck doesn't have the 12-pin socket, it's included in the camera/TPMS kit. The instructions, which assume an F250, also assume the wiring harness has the required plug for the back of the 12-pin socket in the kit.

I believe there exists a kit for TPMS only but I don't know the part number. I also don't know if it works without 360 cameras. You won't find it if you search ford parts for an F150 truck. It's associated only with SuperDuties but it works on Gen 14 F150s that are suitably equipped.

That’s right. We need to add the harness and the kit for gen14’s with tow technology and 360 cameras. Tow technology package for PB anyway is max tow without the axle, higher rated hitch, and bigger rear brakes I believe. The brake controller and the pro-trailer assist stuff.

I also have an XLT and the temps are not there. It may only be available with the digital gauges.

There is soooo much info on this topic I sure wish that there was a comprehensive detailed single source explanation, with part numbers, either/ or choices, etc.

I agree and am okay with that. At least, I would be if my TPMS alerted me for low PSI. Unfortunately, it doesn't, and I don't know what I've got set wrong.

The '21 user guide does say it will alert for excess temp but does not say what that excess temp alert level is.

There was a setting when I connected the trailer for pressure setting. I set mine for 60psi. I assume it will alarm if pressure drops too low.

I set mine for 80 when I had pressures of 65. No alert. Maybe it has to start higher than the alert level and drop? I'll test that using the spare tire on the trailer. (I bought an extra sensor for the spare. I'll reprogram the system if I have to mount the spare.)

I appreciate everyone sharing their insights. I have a 2021 F150 Powerboost Gen 14 with the towing technology package and 360 cameras. I could see the Trailer TPMS in the towing menu, but like others, I only had the 2-yaw leads on my 12-pin connector. I replaced the rear bumper trailer wire harness (purchased through Ford Parts from Bob Howard Ford - $109+shipping) and installed an F250 trailer camera, TPMS, and yaw sensor on my trailer (purchase on eBay for ~$400). Everything worked perfectly, and I have a wired rear view camera, TPMS monitoring, and backup pro assist working for my airstream travel trailer.
