Our Ford Raptor has a similar learn mode for the TMS sensors that you have to do each sensor 1 at a time and only have so much time between each tire. Maybe it is more for the off road vehicles that this is included as "standard" equipment??

The way I understand it the higher end tools will still work but you won’t have the latest vehicles in it without the update. If you bought it this year in 5 years it would still work on a 2023 or older vehicle but nothing newer.
My 2009 chev truck you could just let a few psi of air out of the tires and they would learn. It had the procedure in the manual. They changed that sometime as my 2016 truck would not do that you needed a learn tool.

Not sure about other makes, but definitely a Chrysler thing.
It will work without wifi, I let the subscription lapse as my stuff is older and it still seems to work, they have the occasional sale, second year half price sort of thing but so far I haven't bothered, but at some point will probably have to. I updated everything just before the "free" one year was up.
I ordered it from Wal mart, they had a sale and beat Ebay and Amazon deals.
It is an MS906, got the number wrong before.
There are other manufacturers that make some similar and powerful tools, one could change the odometer reading, mine won't do that.
The ts401 looks like the one I have, it was $300 when I got it, still figured it has paid for itself vs taking it to the dealer.

My brother has a couple of vehicles that have tpms ( or is that pms ... were not sure ! ) but yet old enough they do not show the actual pressure so it alerts to a low pressure but no idea what that pressure is in the tire so it plays mental games wondering how low is it. He always ends up at one or more different tire shops as they mess around doing a relearn and it doesn't always go so well. While I gather some sensors can have their battery replaced it sounds like its a lot of messing around and I assume tire shops just throw the old sensors and put new ones in when they run out of life ?
I looked up that Autel number and yes I sort of assumed the number was slightly off, they have three variations of the 906 model to make it even more confusing. At least from what your saying the unit still works with the current loaded vehicles rather then it becoming a dud, that is until one would try to work on a newer vehicle and by that point it probably takes a new updated diagnostic tool anyway. Just another money maker by manufactures to rape anyone attempting to work on vehicles and that includes every mechanic and shop out there, a revolving door of making things obsolete. I get the idea some of the diagnostic tools will do tpms as well but in a much more expensive package of course as one of those 906 models will do tpms. That 401, yup that is the one they don't show on the new updated Autel website and is the one that Princess has on a fire sale for 132.00 assuming they even have any now as it won't look it up on their own PA website but if they still had any in stock that would be an option for a unit and a more palatable price.

I have a maxisys diag elite that I got at princess auto, it shows some live data, as well as the codes, and it does read multiple systems, engine, body, abs etc. It has wheel speed live data so you can see if one is not working. It has worked well, and is a lot cheaper than the 906.
The 906 is really a tablet, you can surf the net with the wifi, I wanted it mostly for the bidirectional control.
I see princess auto has the tpms sensors now as well, a lot of tire supply places sell them it seems now.

I don't see anything of that type of diagnostic tool on the PA site now so I wonder if they backed away from handling items like that which start going up in price due to lack of sales, no doubt some reason for the absence. As to the tpms sensors, while I haven't had reason to be seeking them out yet I get the impression that its an item that tire shops would carry some generic brand of some sort as a lot of tires dealt with these days on vehicles have that to content with and batteries that have died and tossing the units for new ones or installing new stems in the old monitor if its still deemed ok I would guess.

Have had to replace a few sensors, they were $170 from Chrysler, kind of expensive. Tire repair supplies place had generics for $35, never tried them yet.
Town & country had the stems corrode out, but could get replacement stems at Piston Ring for $7.
I don't think I could go without a scanner now!

I sure can see why it makes sense even more these days with newer vehicles to have some way of finding out what that stupid idiot light it on for, I can well imagine if one doesn't hold your butt hole just right the light has an excuse to come on !.
On a different topic I came across this handy wheel torque interactive chart and I plugged in some various vintages of vehicles and it seemed to work, its easy to forget what the wheel lug nut torque is on vehicles that don't get worked with that much and all sorts of fun to find the info buried in an owners manual.

You mean you don’t just give it a couple ugga duggas and call it torqued?

I will do that with implements ( and of course over done .. more than two uggas ) and then hand check a couple of them with a flex handle to make sure nothing is under torqued if I have the hand tools handy. But with vehicles and aluminum rims which seem to be more touchy as per loosening up if they are going to, I snug them up on a low setting ( little ugga duggas ) and then the final tightening with the torque wrench and even then sometimes I will get a surprise and find some don't turn as they were torqued a bit beyond. Its so random with impacts I find and I don't own any torque sticks but have watched on the torque test channel and they found they were not accurate as it was the impact that determined a lot of what was going to happen paired with the stick and battery impacts did one thing while air impacts did another due to different impact mechanisms. I still remember from years ago with a 3/4 ton pickup that I had brought to a tire shop to get a couple of tires thrown on and I was even standing there as he was doing some of them up and back in that day no one was made to use a torque wrench in a shop it seemed but it was the irony of it all as he was bragging that he knew the feel of his air impact and no worries about it not being torqued correctly. I couldn't tell from what he did as it seemed ok to watch although his anvil was so worn on his impact and the socket kept on falling off. I get home and I checked the torque just to make sure nothing was loose and one wheel end was tight ( using a beam wrench which is a real pain to use vs a clicker ) and then went to the other wheel and being it was a beam torque wrench it tells you what the torque is when the hardware starts to move and they were all around 60 lb, not the 140 that it was supposed to be at. It can be really hard to tell, all it takes is some threads that are dry and a bit rusty and turns harder for the impact and gives false feedback. And not that I have done anything with cars for some years now but the small cars with the dainty four stud hubs, those rotors/hubs can be warped easy if they are over tightened so I was always careful with that when I did any work on a small car.

I hate aluminum rims for the simple reason they can tend to work loose. My wife’s car has had a couple work loose after I changed over the winter tires, did it myself and cleaned everything good, torqued them then retorqued after a couple days. Dad’s truck at the start of winter ruined all the studs after it worked loose after changing the tires. I now torque them a bit more than they call for and check them with a torque wrench a few times after having removed them. I’m thinking it’s because of the tapered lug nuts, I’ve never had a semi tire come loose after having one off.

Ya. We always torque the wheels on our vehicles. Seems like an impact is hard to get them evenly torqued. Also I tend to go around them all twice as the first couple the get tightened always seem to move more once the others are tight.
Actually I need to find a new 1/2” torque wrench as mine the handle got damaged and is annoying to use.

I remember quite a few years ago Ford was having some issues with the lug nuts loosening on the half ton pickups and I never did know what style of lug nut that was, if it was tapered or not as I was only assuming most lug nuts are tapered on passenger vehicles but I may be mistaken. I feel as well that aluminum rims while good in some ways have issues when it comes to loosening up, some corrosion buildup that doesn't allow the wheel mounting surface to lay completely flat to the hub but then mushing as its driven some, and also a gripping effect while mounting them on that I think caught up with me about three years ago with not being careful enough in snugging up the first nut as in zipping the lug nut on quick although not over tightening and unknowingly set that wheel up for becoming loose. To try and explain my theory, the wheel to hub was centered because of the hub shoulder and the wheel fits snug over that shoulder but I believe the wheel was not "clocked" properly and the first tapered lug nut that tries to center/turn the wheel with its taper didn't as I spun the nut up too fast and gripped/locked the wheel to the hub, then the remaining lug nuts could not overcome that and instead probably only contacted one side of the taper in the rims stud holes. I've swapped winter to summer rims for years on this truck and never once had a problem and then had that one wheel loosen up and I heard something when driving in town, had not rechecked the torque yet and had driven about 250 km which was too far before checking them. I pulled over to a parking lot and started checking and sure enough the one wheel had all loose lug nuts, what a confidence deflator that was. I tightened them up and when I got home took the wheel off to see what sort of damage there was and I had caught it in time, there was a bit of aluminum flakes from the threads on the studs starting to work a bit at the hole but nothing that stood out damage wise and the tapered surfaces were good, put it back on and torqued it up and rechecked it etc a couple of times after and all was good and never had it happen since. So I figure that was all down to operator error, mine !. In reading about lug nut issues when searching the topic online, the theme seems to be aluminum rims and some theorize that some of it has to do with thermal expansion and contraction, I wouldn't doubt that is part of it as well. I've never had issues with older vehicles that had steel rims if put on properly to begin with.
My brother took an suv to a private mechanic in town that I've had work done on vehicles as well as my brother was hearing this noise ... yeah, turned out to be a loose wheel after a tire shop had the wheels off and my brother had even checked them after but still something was not right and one loosened off. That mechanic said he tends to torque aluminum wheels up more than what they call for due to the issues that he has seen over the years, I don't know how much more as that can bite a guy too with stressing the lug nuts if one gets too carried away. Long and short is check the lug nuts at least once after if not more if one is in doubt. There is a reason why tire shops or at least some put on the sticker to say come back to retorque in 80 km.

Here is a tire inflation chart for P series, LT series, LT flotation series and some other strange series of tires in Europe. Its quite helpful if one is not running heavy in a pickup that has E rated tires that could be inflated as high as 80 lb for example but not really know whats a safe level to drop the pressures to after doing a scale weigh in on the front and rear of a vehicle first.
