Need help with TPMSII

[SC Joe]

Similar. I got my Jayco with a card that said to use TPMSII app (and did NOT get the serial numbers or bar codes of the TPMS systems). I called RV Life and got no help. They directed me to Jayco CS. They directed me to the Tredit app. Trying to use it now, and after granting the location permission (which it automatically asked for), now I am trying to sync my tires and I am getting permission errors ("Permissions have not been granted.") with no clue on what permission might be missing.

I also noted that some pre-mounted TPMS systems may not be 'activated'. I bought a cheap TPMS diagnostic tool from Amazon and will try that too.

Hopefully in the next day or two I will have an update!

Thanks for the update. Sadly it was a month ago today I got similar updates.

Hope to get my trailer out soon too. Home without wheels has been keeping me busy lately.

My update: Little joy.
A. TPSII (On Android phone or Chromebook) never finds any devices
B. Tredit gives me a permission error on Android, and found ONE sensor on Chromebook (even though I tried resetting the TPMS systems and releasing and re-adding tire pressure.
Note: Devices I have tried (with no luck): EL-50448 and EL-50448. They seem to be unique for car manufacturer ($6-$12 ea), but none listed as Jayco. Generic ones cost $125 or so. I guess I will try to contact the dealer that sold me the RV. Some auto stores might have free use of TPMS diagnostic tools also.
Still working.
Almost just want to buy $20 new TPMS system, but would rather use the ones I already paid for.
Tredit app also lists some phone numbers. Guess I will try them on Monday.

Today I got a response from Jayco. They sent a new set of instructions for the TMPS for my 2025 15mrb. It outlines using the Tredit Tire App (not the TMPSII app) for the TPMS system.

I haven't had a chance to test it out yet but will post back as soon as I do.

Can you post those instructions please.

Can you post those instructions please.

The Tredit Tire app is available free online. I haven't tried it yet, but I'm told it works (sometimes) if you release air while pairing because it can pick up the pressure difference. Good luck.

Thank you

Just an FYI on why the air loss makes a difference. Almost all TPMS sensors have a long battery life largely in part to going into sleep mode (like a laptop can do). Two ways to wake up a tpms sensor is to have motion or have a relatively quick pressure change. ~CA

That's exactly were I'm at now. I had an excellent CS rep at Jayco really try to help. She did what she could as far as researching and advising, but it appears the solution is partly (mostly) unavailable.

The instructions for the system are in the app. They reference the special tools you need to make battery changes. I didn't get them. Did you?

No , never did.

On the newer TPM

No , never did.

The TPMS system from Tredit that most of us are discussing is the in-tire TPMS sensor, versus the on the stem version that had the special tool. The in-tire sensor won't some with any tools.

I have a new compressor that can fill tires faster than my old one so I plan on playing with the TPMS stuff this week as I prep for a trip.

Attached is a JPG capture of the instructions Jayco sent me. I added the PDF as well.

Had the trailer home today and tried all the following to get the sensors paired in the Tredit App (iOS):

1) let 10psi out, nothing
2) added 10psi, nothing
3) drove camper around for 5-6 miles, nothing

I called Tredit at their Elkhart location. Customer service (option 1) quickly stated that the batteries must have died while trailer was waiting to be sold (unlikely in my opinion). They are sending me 3 new sensors, and even offering to pay labor for having new ones installed. All stated as warranty coverage.

While that’s pretty nice, I’m not sure I’ll go to the trouble.

I’m thinking I may just get an add on tpms as others have done.
