TPMS Learning Procedure?

[Owl]

You didn't say what TPMS you bought. The above TPMS relearning tool will work for helping your tires relearn what position they are on, but most likely won't "program" them. The Bronco (according to others) does that automatically (i.e. figures out what position the tire is on -- LF, LR, RF, RR).

The Schrader TPMS say you have to program them before an install, but I wouldn't think that'd be necessary (but who knows). How does a TPMS know if its been installed?? I don't know. You might be able to simulate programming before install by letting the air out of the tires. Just a guess.

Again... what TPMS did you install? (Or at least) who installed them? You can probably figure out what type they are by the installer. For example American TIres (Discount Tires out East) I believe do use the Schrader valves. How much did they charge for the TPMS?

Without knowing which TPMS you used... you might be using one that will only work for a Chevy, and that will never work for Bronco.

Again -- which TPMS, and what frequency is it using? I think Bronco uses something like 315 MHz.

This is what I bought (Scrader):

So after plugging a slow leak today, won't reset from 80#! It was hours ago....?

Never updated this, but TRUST your readings! Turns out my mechanic's gauge was broken and I really did have 82# in the fixed tire!!! Immediately after dropping down, TPMS adjusted.

I agree with this.
There are a lot of different TPMS sensors, some will not work with the Bronco.

315 MHz is correct for Bronco
The correct Ford part number should be ML3Z-1A189-B or Motorcraft number TPMS68.

I went with the Schrader oem which was ML3T-1A180 also listed as TPMS68. The truck would not pick them up automatically and I tried the relearn procedure with letting air out of the tires and that didn't work either. So I bought that TPMS19 tool which worked for the relearn. Everything I read said the ML3T-1A180 sensors needed programming but I'm not sure what the definition of "programming" is for sensors. I read that the sensors I bought needed to be activated/initialized/triggered and then learned to the vehicle. It's not really clear how certain sensors work with specific vehicles but I'm thinking that might be on purpose so people will go into a shop or dealer to get it done. I think the Schrader EZ-sensors should get picked up automatically since they don't mention programming, but I'm not 100% sure. spartacus1882, do you know the part # of the sensors used in your wheels/tires?

I went with the Scrader EZ-Sensor, but confirmed with America Tire that they could and would program them before installing. As I remember it was $22 per tire for the install/balance/program. Worked like a champ for me.

They came installed on my wheels when I bought them. They are BH Sens 315mhz

 

[Owl]

Well, if you go to Amazon and type in "BH Sens TPMS" you get a list of them. Some 315/433 MHZ, and for the 315 alone. They all say "programmable", and that it takes 3 seconds (or something like that). Maybe they weren't programmed.

From Amazon..
Programmable - Only take 3 seconds to configure to specific application. Supported by ATEQ, Matco, SnapOn, Mac Tools, Monster Tools, KTool, NAPA Tools, Bartec, OTC branded tools along with many others.

I'd call around to tire shops and see what they'd charge to try and program them with one of the above tools.

But... under the 315 MHz title it has this...
BH SENS UVS3041 ong Electronics (BH Sens) 315MHz Universal Sensor/OE Quality (must be programmed prior to install) with rubber valve

Good luck!

Just adding since I am working on new wheels. I have all the tools for TPMS stuff so I can program them if needed, but Ford Performance also has a kit for the Bronco M-1180-BR5.

Oh let me add to the confusion....

The reason for the confusion is that there is not just one answer, or even one path, to get a TPMS to recognize a signal from the sensor(s).

There is a difference between programming a sensor and a "relearn" of a receiving system. If you buy an aftermarket sensor that will fit multiple systems then you have to program them as to what signal to put out, this takes a special programming tool; and the next step is to relearn the vehicle's receiving system. On the other hand, if you buy sensors that are already puting out the correct signal for your vehicle then you just have to teach (or relearn) the system to what signals to listen for. To compound issues there are multiple ways to teach the vehicle, multiple ways different Ford vehicles will enter relearn mode, as well as some being fully automatic. The automatic way just takes time, entering into a teaching mode is a timesaver or a necessity in an non-automatic system. See clear as mud.

I deal with mulitple fords (explorers, bronco, and superdutys) and use winter tires on some of them as well. What I have found out is the brake pedal and key switch way requires the ford relearn tool. The hazard flasher way requires you to drop pressure in each tire. And, last but not least with the '23 bronco it seems to be the most willing to automatically listen for a signal and go with it. My professional guess is it has multiple receivers, as signal strength is not a reliable way to judge distance.

The good news is as we progress through model years the manufacuters are making TPMS more user friendly as we go, however you still have to know your vehicle and what it takes, or pay someone that does. The reality is the TPMS are just simple eough where info is hard to find, as the people that know understand it and don't think about sharing, yet complex enough to be confusing for the DIY'er. We have been living through the wild west of the TPMS, don't worry civilization is coming.......

EDIT: The 'hazard lights' way to enter relearn mode is only for tire rotation, you cannot add another sensor(s) or number(s) to the car with this method. To add a number or replace a number you have to enter the progamming mode via brake pedal and key switch method.

Bumping an older thread.

Are we sure it's 315 MHz only for the Bronco?

I'm getting conflicting reports online that mid-way through MY2023 Ford started mixing both 315 MHz and 433 MHz (so that some vehicles come from the factory with 315 MHz and some come out of the factory with 433 MHz). This "apparently" applies to at least the Bronco and Bronco Sport (both of which I have) for when I input my VIN at Tasca Parts (for example) I'm getting a "you may have either, so go to your dealer" message.

What's the best way to sort this out? Can I enter my VIN at Ford and get the info? Or do I need to buy a tool? I guess I can go to the dealer (ugh!) or stop by the local tire joint and have them read it, but I'd rather just be able to DIY for these vehicles and all future vehicles....

It used to be soooooo simple!

TIA for any thoughts you might have.

Sent you a PM. Thank you VERY much for checking this out for me.
