Supposed to arrive next Fri'. I'm sure I'll be asking a few questions. I'm not really all that savvy w/ this stuff LOL

As I had mentioned after I had bought mine, the worst part was messing around to get a log in to Autel because I was doing something wrong with their fill in form to create an account, once I got past that and dug up the update and downloaded to my computer and plugged in the 508 to my laptop to then download it to the 508, I was well on my way as it turned out. You probably have already realized that but the 508 MUST be updated before you attempt to use it. I actually plugged in the charger for the 508 to begin with and left it to charge just in case before I did anything else although I think mine was fairly much charged out of the box. The video ( even though there is no sound for a fair bit of it ) that had been posted on this site was what I followed to find the right area and lines to choose to get me to the program for my truck for the front and rear separate axle settings. Only because I had the truck in a garage did I use the "run" mode on the truck without the engine running and had a higher amperage charger on the battery to maintain good voltage for the process but otherwise get the 508 to the right line where it asks to plug it into the obd2 and start the engine and plug it in and then change the numbers to what you want.

 

The pressures you choose to put in don't necessarily have to be quite as low as the lowest pressure you plan on running if you want the trigger point for the tpms alarm to go off sooner, hopefully that makes sense but if not I can elaborate.

From what I understand from elsewhere, you just have to lower the setting enough that when you lower the tire pressure(s), you don't trigger the system.

 

The accompanying info on Amazon (the 1 screen grab) says you can Read/Write Tire Type/Pressure. What do they mean by 'type'? Is that size lost in translation?

Yes that's right, even though the factory placard pressures input into the trucks system were the actual pressures you read on the door frame sticker ( mine did read 60 front / 80 rear on the Autel unit ) and I did try with the rear tires by lowering them to close around 60 to see if that was the point where the alarm would be set and seemed to be in that ballpark as was suggested on here. It may not be exact figuring and I didn't spend a lot of time experimenting but seemed to be around a 25% reduction from the placard set pressure to when the alarm would go off ( pressure reading went from green to orange ) . So from that rough deduction I figured if I wanted to run a an actual minimum physical pressure of 40 pounds in a certain tire I will take a pressure number and subtract 25% and see where I land, so I chose 48 - 25% = 36 . So if correct that would mean it would trigger at around 36 pounds and it did actually seem to be close in there when I lowered a tire down to around that and it triggered the low pressure warning. Of course that means I must set my tires pressure at a cool morning in the shade temp ( coolest ambient temp of that time of year ) in order to avoid the alarm going off or running too low a pressure for that matter. Also doing that means if I put a bit more air in than lets say the 40 pounds to carry more load, its going to take whatever pressure above the inputted 48 pounds to trigger a high pressure alarm. I assume the system won't actually tell me the pressure is high but will just trigger it to go off to alert me something is wrong. I won't claim I nailed exactly the right placard pressures to input and if I start hauling heavier loads I will have to certainly jump up the rear axle placard pressure to avoid triggering the system all the time.

 

As to that wording they used, I believe they used the word "Type" to explain the construction types of tires as an LT type tire for example requires more air pressure to carry the same load as a P rated tire of the same tire size due to the heat that the heavy construction LT tire would produce otherwise from flexing over the wimpy P rated tire. But the reality is that its asking for a tire pressure to set the system at and not a tire "Type". Which reminds me, I believe there is a metric or English setting one can choose for the unit and if that was there I must have chosen the English/USA readout of PSI. That is how the list of pressures to choose from was listed and its by 1 psi increments all the way from 1 psi up I believe. Once one is in that screen to choose the desired pressure to reset the axle in question, its hitting the up or down arrow to scroll to the highlighted psi you want and hit yes to choose it. It could care less what tire type is on the vehicle, that is more a matter of what psi to put into the system if for example a person was taking a half ton that came factory with P rated tires and the door sticker said 32 pounds of air, now you installed LT tires and those tires called for 50 pounds at the same max axle weight rating and wanted to set the vehicle to that pressure. But the tool itself doesn't ask for anything in that way, what tire type it is ... it only wants to know what pressure is desired to reset for the alarm to circle around it for our tailored purpose.

Today for some reason and am guessing because it was a bit colder, plus I had bled just a little bit of air out the other day to set to what I thought was going to be our new cold temp average for these days but it had dipped colder and then I drove it first thing this morning. That was enough to trigger the rear tires as I guess I didn't have the placard set pressure quite low enough. On my way home one of those tires decided to go into the green, it was on the side of the highway facing towards the sun, the other tire read the same pressure but stayed orange. Ok so its not set quite low enough, time to click down the placard setting just a bit as its too touchy, as I said just experimenting to see where its happy place is without triggering for no good reason. That tire which stayed in the orange, I inflated the tire with the truck running after having changed the placard pressures and indeed the horn went off and I stopped the air and checked with the tpms tool for pressure reading and sure enough it had honked right at the new placard pressure setting. However I then lowered the pressure back the few pounds to what I wanted.

 

I must have misread the choices of tire pressures the other day and took the "line numbers" as psi in that moment of scrolling fast as the lowest pressure the unit shows for this vehicle program is 26 pounds.

 

By the way the 508 as I set up the vehicle type etc and go to where it will have to access placard pressures on the vehicle, it says "start vehicle and then plug in unit". I have the cord on the unit already so plug it into the vehicle and it reads the vehicle and then goes from there to either read the existing pressures only or chose the choice of changing the placard pressure figures by axle.

I just got a Thinkcar 869BT, it has free lifetime updates, is bidirectional, can do FCA, force Regens, and etc.

 

This has been a fantastic tool so far, you can read about some of my use here:

My Autel TPMS scan tool arrived today. I have a question which I've asked in a separate thread:

 

 

(The current thread title doesn't differentiate between OBDII & TPMS scan tools)

Yes it help for me

I see this troll added some idiotic link to my prior post, I have sent a request to delete this persons account but in any event everyone can disregard whatever garbage this troll is peddling.

 

Update; thank you to the moderators as that scammer post was deleted promptly.

      2027 GMC Sierra: Official Discussion

      By tararebecca · Posted

      I agree, simplicity and reliability matter more as vehicles get more complicated. A V8 work truck option with fewer electronic features and a stronger warranty would definitely appeal to a lot of buyers who use their trucks for real work. Customizing it with trusted outfitters is often the best way to get exactly what you need.webcrimsNY

      2026 Sierra 1500 Denali - Sound upgrade?

      By artistemorbidity · Posted

      I’ve heard similar complaints from newer vehicles where the factory “premium” systems don’t always live up to expectations. A good installer should be able to improve the sound without turning it into a bass-heavy setup. I’d look into upgrading the front speakers, adding a quality DSP amplifier, and possibly improving sound deadening first—those changes usually make a much bigger difference than just adding a subwoofer. Hopefully someone local can recommend a reputable installer in the Las Vegas/St. George area.

      Do you remember that Harley Davidson was more successful (solvent) when it produced about 60% of the market demand (by design) and forced wait times of up to three years? Even when your turn came around it was, "Take what we are giving you or move to the back of the line and start over". HUGE markup's were 'normalized' and dealer killed. 40% markup and no floor plan? What's not to love? Greed will kill them yet. They have surplus production and customer base is tanking. And still they think nosebleed pricing will work.

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.
