You still haven't answered my question. Discount Tire installed OEM (sic) sensors you purchased but what did they do? Break the bead and replace the sensor and valve stem... and anything else? Use a TPMS reader to read your new sensors or did you just drive off expecting the owner's manual procedure to pair the sensors with vehicle?

I'm saying someone needs to stand next to each wheel with a handheld TPMS reader to verify you have functioning sensors. Most new sensors need to be woken from their dormant shipping state. Dozens of sub-$20 "clickers" on eBay for this purpose but a full TPMS reader also does the job. That reader will copy the ESN from each sensor, then with cable connected to the OBD-II can quickly write the ESNs into the vehicle in their correct position for the PSI display.

If Ford changed the sensor vendor (OEM is Ford's supplier, not the OE part which belongs on your truck) between 2014 and 2015 but had overlap as has been suggested, then the sensors you have might be incorrect and will never work. If the sensor changed then using a TPMS reader set for 2015 should read your 2015 sensor but would not read a 2014 sensor if set for 2015.

If you had 2014 sensors in your 2015 wheels then that might be how a tire shop told you all sensors were dead. They used their tool set to 2015 and didn't think to try 2014, That still doesn't answer why your truck isn't seeing the sensors and why I say to plug the TPMS reader into the truck and try to read it as a 2014 and again as a 2015. Determine what is in the truck.

 

yes... Installed new sensors...both Discount & Ford used a scanner...both set the scanner for 2015

 

After several attempts at Ford dealership & Specialty Service Shops. All 4 OEM sensors replaced. One sensor was "dead". All service shops wanted too charge over $500 for "BCM" test & replaced (no other sensor or mod issues).
I purchased Autel TS408 off EBay.
Step 1...scanned & retrieved esn from each sensor
Step 2...Loaded ForScan on laptop
Step 3...old sensors esn was still in BCM
Step 4...rewrite all 4 sensors with new esn
Step 5...drove the truck 2 miles... TRUCK RECOGNIZE ALL NEW SENSORS!!!
Saved a lot of money (minus going back & forth too different shops)
YOU HAVE TOO PHYSICAL REWRITE SENSORS ESN IF YOUR VEHICLE DOESNT RECOGNIZE AUTOMATICALLY

 

I don't doubt that some times some people get lucky and the truck automatically detects new TPMS sensors. I don't see in my owner's manual a statement lending me to expect mine will without significant song and dance going around the truck partially deflating tires. But there is nothing like brute force reading the sensor ESNs (Electronic Serial Number) with a real TPMS reader (not just a clicker) then attaching OBD-II cable to write the ESNs into the truck. This also gets puts the sensors in the correct corners for those with tire pressure display. No need for the "horn honk partial tire deflate" procedure. I found it mildly amusing the horn honks and lights flash when the Autel tool did the task to a friend's 2011 F-150.

Autel makes cloneable sensors. The Autel TS408, TS508 (and no doubt other Autel tools) can initialize an Autel MX sensor with the protocol, frequency, and ESN your vehicle requires. You can make a set of winter wheels with identical TPMS ESNs as your summer wheels so nothing else is needed when swapping.

questmoble should not have needed Forscan, his TS408 should have been able to do the job via OBD-II. The tire shops he visited must have been incompetent.

 

You are correct... Im just glad I was able too figure it out... I do like ForScan...more of a behind the scene of your vehicle... I just make sure I backup before I make any things

 

Not to be argumentative but as i pointed out in the other TPMS post, ive now had at least 10 sets of wheels/tires on 4 different 13th gens (just threw a set of 2022's on the other day) and not one of them required anything more then driving for the truck to re-learn. This goes along with a lot of others on the forums/facebook, as well as my local Discount Tire, and my local Ford dealer....local Ford tech actually laughed at me and said, "just drive it brother, truck will fix itself." If i got randomly lucky that many times, i should be a lotto winner by now, lol

The owners manual for both the 2015-2020 as well as the 2021-2022 specifically states that the "song and dance" you mentioned is ONLY if your front and rear tires require different PSI from the factory(even throws in a bold statement), the 2019 owners manual even goes into detail explaining that the low pressure warning is set at different levels for those very specific vehicles and they dont want people relying on that.

I do agree with you that new sensors that are either OEM or Aftermarket do need to be "turned on" so that they arent sitting on a shelf wasting battery life.

 

No, it does not say "only". Nowhere does it say new sensors will be automatically detected. Nowhere does it say it will learn the new positions after a rotate without the "reset procedure". When different pressures are used front and back the vehicle needs some form of reset so that low pressure alerts properly apply for front and rear. Ford doesn't much care if the pressure displayed LF is mounted LR unless different pressures are required front/rear.If you do not care whether tire pressures are displayed in the correct corner after tire rotation then no reset is required. The Autel TS-508 or similar real TPMS reader tool makes this easy.

 

the only time it mentions the “reset procedures” it states this at the beginning:

2021: You must reset the tire pressure monitoring system after each tire rotation on vehicles that require different recommended tire pressures in the front tires as compared to the rear tires.

otherwise, why wouldn’t it just say “you must reset the TPMS after every rotation, why did it specifically call out the different factory psi settings?

2019: Note: You need to perform the tire pressure monitoring system reset procedure after each tire rotation on vehicles that require different recommended tire pressures in the front tires as compared to the rear tires.
Overview
To provide the vehicle's load carrying capability, some vehicles require different recommended tire pressures in the front tires as compared to the rear tires. The tire pressure monitoring system equipped on these vehicles is designed to illuminate the low tire pressure warning light at two different pressures; one for the front tires and one for the rear tires.
Since tires need to be rotated to provide consistent performance and maximum tire life, the tire pressure monitoring system needs to know when the tires are rotated to determine which set of tires are on the front and which are on the rear. With this information, the system can detect and properly warn of low tire pressures.

The 2019 dumbs it down even more with a better explanation, it even explains how if you are running 34 up front and 38 in the back and swap them, you’ll get false readings.

it also doesn’t tell you to do any resets after tire changes, wheel changes, changing from a spare back to a regular tire, or after a regular tire rotation.

The whole section for the TPMS reset starts off with a disclaimer about how the reset needs to be done if there are two separate sets of pressure set per the factory.


and yes, if you read my other post, I swapped wheels around and my truck knew where it was.

it’s amazing that you think I’ve been lucky 10 times on 4 trucks along with the hundreds of other people on all the forums and groups. Again, I even lowered my RR tire and swapped it to my LF this past weekend and the truck swapped.

using a commercial grade tool will work, just stating that per hundreds of posts, my 10 lucky instances, discount tire, and ford…nothings needed.

 

Hundreds of threads just like this:

https://www.f150forum.com/f118/reset...379945/index2/

all is lucky guys with secret fancy alien trucks.

only time people have issues is aftermarket sensors or eBay “ford” sensors.

even the guy you are responding to ended up just getting new sensors and then even stated “if your vehicle doesn’t recognize you have to manually enter….”

 

Then why do you not have anything to contribute other than complain? Your “advice” did not work. Contrarians apparently have no reading comprehension skills, have not comprehended their own copy/paste content. No where does Ford state the vehicle will self-detect new sensors. No where does Ford state the vehicle will correct the sensor locations after rotation. Quite the opposite, Ford states the reset is required for vehicles which need to know where the wheels are mounted. How could this be a more obvious statement that the vehicle can not detect wheel location without help?

The O.P. dutifully obeyed your “advice” to the point he was convinced the BMS controller was defective. Until finally realizing he could buy a used tool on eBay, try it, then sell it or keep it whether it worked or not for much less cost and risk than replacing the BCM. And it worked. The procedure that has worked for all manufacturers since the in-tire TPMS mandate took effect in 2007.

As I have said many times, “Good for you if you are so lucky the vehicle autodetects new sensors.” I think any competent tire shop should use the proper tool from the start so the sensors work the first foot out the door and the kind of thing that happened here is avoided. Only takes a few minutes and is necessary to know if the sensors are working at all.
