For what’s worth… I just picked up a 2022 3500 DRW… I have an Autel TS508 that will change the pressure alert setting, but not on the 22… in the Autel I selected a 2021 SRW and successfully changed the pressure setting… set mine to 65 from the original 80, also the myChevrolet app updated the pressure after about a day…

has this ended up working and keeping the lower pressure threshold parameters programmed?

 

[mjgood]

Has worked with no issues, truck and OnStar have no complaints…

thank you. looks like the 2022 is still supported, but the '21 is. i think i am going to get one and try and use it like you did. looking at the supported tpms part sensor numbers, and the '21 and '22 look the same.

if you have a dually I would recommend setting the valve stems opposite each other rather than lined up, the TPMS tool can’t tell the inner from the outer when the stems are next to each other… not needed for setting the pressures but when using tool for rotating the tires

i have a '22 srw 3500.
any other tips or suggestions?

My rears are set at 65psi, below 50psi will trip the alert, so 15psi drop from set pressure.. don’t know what the upper limit is, I have aired them to 80 for towing a 5th wheel, think I got close to 90 when towing with no alert…

i like to run mine low. i will try and set the thresholds around 50

after thinking about it, I feel that it will work by choosing the 21 model. I have a handheld TPMS relearn tool from Amazon that I used on my '20. It works fine on the '22 as well.

interesting find yesterday. '
so I had a shop attempt to reprogram the thresholds nearly 2 weeks ago. they said they could do it no problem.
they were using an autel scan tool, a big ipad looking one with wireless obd port connectivity.
the tech did the programming, but it didn't work. the rears still showed low, then he went to relearn all of the sensors and they all went blank. we thought they would reset after driving a bit, but they did not. the tech was busy with another job, so they asked for me to come back. work has gotten in the way, so i haven't been back yet.
in the mean time, i relearned the sensors with the cheap amazon tool i have. everything is fine, but the rears are still showing low.

so i have been reading about the autel programmers and all the different functions of each. it seems like the one the shop tech was using was one that has all the features. so it should have worked. but i also noticed that all codes and lights had to be clear before programming. so maybe this is why it didn't work. 🤷🏻‍♂️

I placed an order for the Autel TS508, it says it can reprogram for tire load index. should work, just waiting for it to arrive.

Here is the interesting find: on my chevy app and on my chevrolet.com, both show the recommended front tire pressures for my truck as 50 psi. 🤷🏻‍♂️ I know for a fact the recommended pressure is set at 60 from the factory, I have a 3500. it has always showed 60 until just recently. the app still shows the rear recommended as 80.
so this tells me the shops programming took affect for the front, but not the rear. I wonder why? I wonder if there was a step missed?

I am debating whether to go back to the shop tomorrow and have them reattempt to program, or just wait until the ordered unit arrives and try myself.
it the shop can do it, i can return the order...
what to do...

Well, buying more tools is never a bad thing. If the scanner you bought is a full two way then you can perform some of the advanced relearn tests like on the NOX sensors should you ever have to replace them.
You know the old saying...if you want something done right, you have to do it yourself.
Not trying to slam your shop, just saying that you'll keep at it until it's right.

Sounds like the shop missed something, I attached a screenshot from the Chevy app, my tires were originally all set to 80psi..

 

[kylant1]

so i just got the tool.
decided to just go ahead and use it.
it took quite a while to register it and update it with the latest software.

took it out to the truck and hooked it up. went through all the proper selections. even selected 2022 model. everything populated the way it seems it should.
the tire pressures were indeed set to 50 psi front and 80 psi rear. this confirms the shop did not set the rears.

i reprogrammed the thresholds and confirmed. i disconnected the tool, gave it a few minutes, and then rechecked.
the programmed values were where i programmed them.

i am pretty sure it worked. now I will just have to drive around, then wait and see if the app and mychevrolet show the new programmed thresholds.

if it worked, it took longer to register and update the tool than it did to actually reprogram the truck

 

[flyinhawaiian968]

It will work just fine if your DIC shows it correctly, sometimes it takes the app 24 hours to update it, no idea why.

I went a different route since I already have an OBDLink MX+ dongle, got the Gretio app (iirc, that's @Snipesy 's app) and reprogrammed the sensors for my '22, was quite simple and pretty quick to do, but you do need to be a little bit of a computer techie geek to understand how to change the psi. The Chevy app updated the pressure settings within an hour or two iirc and I've had zero issues with it being like this, including a visit to the dealership who did an update to the truck.

 

[kylant1]

update. it worked. my app shows the new pressures. I am not actually getting a message for the rears stating the pressures are too high 😆
I haven't lowered them yet

 

[DuramaxDanZ71Sport]

Thanks for the feedback. I will be going this route with the TS508.

 

[Snoozer]

I’ve been curious about this for the purpose of selecting a tire that has a load range E or F but requires 65 psi max v.s. 80 psi max.

 

[DuramaxDanZ71Sport]

Picked up a new Autel TS508 for $165. Changed my pressures via the write option. Running max 65 psi load E2 tires and truck wanting 80 in the rear. We shall see how she rides tomorrow. I will report back.

Thanks again for the insight on doing this @kylant1

I would be interested in your process to accomplish this reprogramming on Gretio. When you get some time. By the way, just got back from Kamuela to visit my son and family, and missed the eruption by just a week. Dang! That would have been so cool to see.

 

[DuramaxDanZ71Sport]

Drove into work and no alerts. Reset to 50 psi and lowered actual tire pressure to the same. No issues.

Yes, it would have been cool to see! Had a friend send me some photos from his in-laws house of the flow, it was awesome!

I assume you have a newish truck, an ODBLinkMX+ and Gretio already? If so, then @Snipesy laid out exactly how to do it in this thread HERE

It was pretty simple to do once I had everything together and sitting at the truck to program it! Of course, if you have problems, reply here and I'll try to help you get through it.

Just remember, take the psi you want, say 60psi, multiply that by 110.3, that gives you 6618, then use a hex calc to get 19DB, that's what you'll put into Gretio. Remember, @60psi, it will not alert you until your tires are at 54-55psi, I am guessing here, but the system seems to alert of low pressure when they are 10% lower than the pressure you want (in this case, 60psi).

Make sure to either write down the two hex numbers somewhere BEFORE you modify it if you want to go back to stock! Or just take a screenshot on your phone and save that somewhere.

Let us know how it works for ya!
