I use the OBDLink MX and the OBDLink SX for analysis and active monitoring.  The MX is bluetooth and allows for unlimited vehicle make and models with free updates.  By far the best OBD Scanner and diagnostics aide I have ever used.  Also includes diagnostics for manufacture and vehicle specific systems.

Gangly, sorry for bumping an old thread, do you use the obdlink app or something else?

I use the manufacturers app.  I have not tried to use any other app, but I would be willing to try if I thought it would work.  The OBDLink software still has some limited communication issues with 2020+ GM trucks.

Dumb question - can any of these scan tools allow you access to the TCM to do the transmission relearn?

The TopDon I purchased does offer a TCM relearn function. I didn't mess with it because I like how my truck is shifting currently!

I want to rebuild the valve body in my 8 speed but I have to do a TCM rebuild after. Threw a wrench in my plans that I am going to have to pay for.

I second this. The OBDLINK MX+ allowed for OEM functions. If you have a diesel you can even monitor and force regens.

 

Question if anyone knows. Will it work with the 2022 model GMC? I have looked at many and right now they stop at 2021 most of them. And the ones I am reading on here, such as the MX+, do not state, they just say 1998 and up. I want to make sure since all the other models seem to stop at 2021, will this do 2022? And if it makes any difference it is a half year model. 

 

I have a 2022 GMC Sierra AT4 6.2L

The half year makes ALL the difference. They changed the computer system from Global A to Global B with the refresh in 22.5.

I highly recommend this one because I and my friends have been using it without any problems.

 

Really?  You and your friends all use Caterpillar trucks to drive around in?

I reported it as spam last night when I got the notification.

 

On the actual topic, I ordered a Mucar 892BT scanner and waiting for it to get here. It and the Thinkcar that's the essentially the same model, both made by the same company have gotten great reviews. Got a good deal off ebay plus there was an ebay motors coupon off so getting it for $482.35 shipped. It has lifetime updates so no subscription crap like the TOPDON bluetooth dongle I had purchased. It can still be used as a scanner but to do any actual diagnostics I have to purchase a new one year subscription.

i just got the topdon topscan master, it won't do half of the things they claim on my 2020 silverado. i contacted them and they said it should and to reload the software, still a fail. they claim my truck has a connection problem. funny i can hool up my autel and it works fine.

Why'd you buy another scanner if you already have one?

    • My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page 
    • Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.       
    • We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper. 
    • Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money". 
    • I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.
