Gen2 OBD2 app review

What about TPMS pairing & smart key pairing?

 

Okay. I'll try to install it and check.

 

its my understanding only techstream can do the key pairing due to the dealer running code thinggy.. where you have to take code from app then put into sixe Y then the site generates a code that you have 60 seconds to enter into techstream... Ive personally only been succesful with a mongoose cable for the key pairing. Also, TPMS is all Techstream.

now I will say, the PCB board I had made thats based on ESP32 with sd card slot, wifi and bluetooth connected to a obd2 port. Its basically a MTM... when I get some time my thought is ill be able to get it to work in techstream wirelessly to perform ALL functions. just no time in the day.

 

Are you saying tire shops have no way to do TPMS pairing?

 

personally, I have yet to have one successfully do it. On the 2013 Plugin, American Tire couldn't do it, on the 2017 Prime, Firestone couldn't do it, I didn't have time to wait for amazon sensor, bought one of theirs and they still couldn't add it.

Just saying in my experience only, I know they have those machines, the only machine non Techstream I have seen work is the one Toyota has and it actually showed the ID of the sensor where as the tireshops I encountered they never could even tell me the id... I had to tell them once while attempting to get the light off when they tried to pair all up.

 

Yes and it is a wireless adapter that works with Ford's factory software. They provide a poorly reviewed app.

Black_j is offering a buy link that gets him a commission and has another wild idea he will make Techstream wireless through it.

Not quite. Autel has several ways to write tpms serial numbers to the TPMS ecus that need help. Some of their tools can directly rf read tpms sensors, something Techstream can not do.


Later gen Toyotas and other cars can automatically read newly installed TPMS sensors.

The "free" hacked Techstream can write tpms sensors to Toyota tpms ecu on models like gen3 that need it. You do need the sensor's unique serial number.

 

I work mainly with Techstream installed on a laptop.

The costs have long since paid off back on Gen2. For daily trips I use ELM327, a simple version of a Chinese manufacturer, which allows you to work with many applications, but more often I use Hybrid Assistant, Torque, Doc. Prius.

The adapter offered by Black_j costs $ 140 and it comes with a free obdlink application.
Call it free? Hardly.
Additional service options from $ 60 to $ 90.
In total, $ 200-290.

This may interest a mechanic from a car service who earns money daily. I am satisfied with what I already have, purchased several years ago and working.

When replacing tire pressure sensor TPMS, I have to use Techstream.
Now I am considering something in the form of a small tablet, which can replace a laptop for about $ 100, but without sacrificing functionality.

 

what I never can comprehend, when people on the internet type out their thoughts as if they were true facts... for example, I have no such discount code... huh? did you do any type of validation? Also, I take it you arent aware of what you can do with an ESP32 right? When its coded properly its basically a j2534 passthrough device. That means, all that's needed next is for me to find the new Mongoose Bluetooth VIM and reverse engineer it to work with my PCB board. hahahahha, its truly hilarious the way you folks try to discredit me because I talk about doing things you clearly have no understanding of how it works, yet you parade around the forums as if you a gift from the gods to be here commenting.

its been said, if you don't have nothing nice to say, don't say nothing at all, ESPECIALLY if you have no clue what you are talking about as evident by your comment.

did you know 315mhz is the frequency of the TPMS sensors? Did you know with a ESP32 and boards like the below you can pull all the info from the TPMS?



this is what the data returned from a TPMS sensor looks like.


time : 2025-05-13 13:53:55
model : PMV-107J type : TPMS id : 0b53e7e5
status : 16 battery_ok: 1 counter : 2 failed : OK pressure_kPa: 200.880 temperature_C: 24.000 Integrity : CRC

But... the way you write your words, I don't know what I am speaking about. heh.. makes me blush to think you and others have so much to say about me and you clearly enjoy writing fiction online.

no.. thats what I keep trying to tell people.. you never have to pay anything extra! Ever! Enhanced Diagnostics for all vehicles is included no extra cost.

Now that Autel... yeah the numbers you list sound about right, every vehicle you go to use it in you pay another $30.

<<<<<<<<<-=-=-=-=-=-=-=- Say what you want about the words of others when they review it, I personally take a reviewers words with a grain of salt and that's if i read it. I mean, here you have folks recommending and buying this Autel here and you have to pay $30 for every other vehicle you use it in and no one can confirm sub codes are returned. I guess, I don't see the logic.... if most of you are sooo against the Sodium and Lithium battery replacements yet give high praise to this Autel or any... I truly makes me concerned for those who read your words as from where I stand, most of the loud voices have no clue what they are talking about. Like that johnny sweet cheeks cupcake guy when he was cleaning his MAF. hahahaha the way he typed his words as if they were 100% facts and had others correct him was classic! -=-=-=-=-=-=-=->>>>>

Oh MAX2, everything above encapsulated by arrows was not directed at you.

 

humor me here... did you even know they make a mongoose that's Bluetooth to Techstream? I suspect you didn't know that and its why you gawked at my words. Did anyone here know there is a bluetooth mongoose for Techstream? Cause if not... :: sipping my tea ::

 

Are updates to the Autel free? I assume new car models may mean new codes. In my case I expect eventually to0 need one for my 2025 Camry.

 

I can confirm the OBDLink SX I own when used with the gen 3 did not have much for functionality other than I recall two general ECU's to access. Like basic Engine and additional hybrid battery ECU I recall. I actually left that reader dedicated to my gen 2 Dodge Ram, though that is another story.

I need to take some stress free time to see what the Autel MAXI AP200 can do, as I read and read prior the functionality is there. Didn't help in my situation having very limited data access, if any, on T-Mobile and literally having to purchase a Verizon network phone with plan to be able to use in the location I attempted using for the fob and TPMS pairing. Awesome for diagnostics, live data and clearing codes. Real game changer in my life.

 

Oh, sigh… here we go again. Why is it that people who think they know what they're doing always write these long-winded posts, filled with so-called "facts," only for those of us who actually know what we're doing to immediately see they have no idea what they’re talking about?

Let’s start with your first incorrect statement—freeze frame data.
You claim the MX+ doesn’t pull freeze frame data. Well, I have proof that it does. Here’s the report that was generated from my vehicle when I was diagnosing an issue. So, explain to me how I can pull this data effortlessly, but you supposedly cannot? Is it possible that maybe, just maybe, you aren’t actually using the device correctly?

Next, TPMS data.
At no point did I say that the OBDLink app itself shows TPMS data. What I said was that you CAN pull TPMS data. That’s a fact. When I use the Torque app, I can add a new module to the dashboard, search for the TPMS sensors, and retrieve the PSI readings. So just because you can’t figure it out does not mean it’s not possible. You assumed I meant the OBDLink app specifically, but that’s your mistake, not mine.

Now, let’s talk ECU selection.
Have you ever manually selected an ECU in the OBDLink app? Do you even know what each ECU and its PIDs represent? Because if you don’t, then it makes perfect sense why you’re clueless about TPMS data. The MX+ can access multiple ECUs, but you have to actually select them. This is why your assumptions are wrong. Instead of just saying, "Oh, it can't do XYZ," maybe actually dig into the functionality?

Oh, and while we’re at it—bi-directional functions.
I never once said the MX+ supports things like ABS bleed, immobilizer programming, or TPS programming. In fact, I specifically stated that those are TechStream functions. TechStream is the software you need for those tasks, and I have yet to find any OBD dongle that can successfully manipulate all of those functions—unless using a direct connection to the OBD port with TechStream. Even the custom PCB-based dongle I had made, which supports J***** passthrough, would still require the proper setup to use those functions correctly.

So let’s be clear—you are misleading people.
You write with authority, yet your information is demonstrably wrong. If you’re going to put out a "review" like this, at least get your facts straight so you don’t spread misinformation.

And finally—before you write another review, maybe try using the device properly first. Just a thought.

link to diag report generated in the obd app.... hahaha no freeze frame data? this person out here spittin straight fictional novel material!

 

Oh, and just so we’re crystal clear—I’ve been using Hybrid Assistant daily with the MX+ without a single issue, even today.

And out of the countless people who have purchased the MX+ based on my recommendation, not one has ever said it doesn’t work with Hybrid Assistant. In fact, they love it. They rave about its features and functionality because it just works.

Heck, even non-Prius gearheads who are die-hard Apple fans have gone out and bought a used Android phone just so they can use the MX+ with Hybrid Assistant—and guess what? They love it too.

So, again, are you absolutely sure about what you wrote? Because from where I stand, everything you typed seems completely made up in your own fictional world.

 

This, folks, is exactly what happens when you cheap out on your vehicle—kind of like hacking up struts from another car to force-fit your own instead of just having a proper strut made to lift it exactly how you want. Cutting corners leads to headaches, not solutions.

Who in their right mind chooses the SX when the MX+ is sitting right there in all its glory? Maybe it’s just me, but I went for the top-of-the-line Plug-in model with every available option—I didn’t settle for a base model Prius. And guess what? That decision paid off tremendously. Unlike non-PHEV Prius owners, you won’t find PHEV owners constantly talking about HV battery failures and replacements. That alone speaks volumes.

So, if you tried using the SX on an iPhone with a Prius and ran into issues… there’s your problem! It’s not the company, it’s not the product—it’s user error, plain and simple.

Reading through these reviews, it’s not the tools that are failing—it’s the people who think they know more than they do. The more I see these so-called "big voices" around here talk, the more I realize they’re just winging it with half-baked knowledge. And honestly? This whole situation is turning into a full-blown circus.

 

and only the Gen 3 Plugin will you see three ECUs when using a OBD2 dongle, there are only two in the non Plugin models... haha THOSE ARE THE TWO MAIN ECUS... ha, general access ecu's... definition of half-baked knowledge in its finest example.

 

What are you talking about? What a show with customer service to prove those words. Those "general access ECU's" again are the only ECU's available to be read with the OBDLink App $49.95 price point. Appears same with the MX+ $139.95 price point. Albeit I am all for others investing in whatever those others want.

Appears like I stated, you only demonstrated with your attachment that the OBDLink App shows the Engine ECU data. I confirm observing the same and the HV Battery ECU data from my experience, that is all. Otherwise, I recall no other ECU's being present as options nor have you presented data from the OBDLink App regarding other ECU's.

OBDWiz doesn't even appear to show more ECU's and is limited to 90 PID's. Nothing regarding ABS anything from what I read. No reference to J2534.

In regards to tangents, how do you have a "2013 Plugin Advanced Package with a 2.0L M20A-FXS engine, a 8.8 kWh Lithium Battery, and AWD with a ~260hp Electric Rear Motor? "

Any references regarding other than you being the source of the information?

The 2.0 L M20A-FXS appeared in the gen 3 Plugin (2023 - present) as well as the following:
2018–present Corolla Hybrid (MZEH12)
2018–present Lexus UX 250h/260h (MZAH10/15)
2020–present C-HR Hybrid (MAXH10)
2022–present Corolla Cross Hybrid (MXGH10/15)
Toyota Dynamic Force engine - Wikipedia

The 8.8 kWh Lithium battery appeared in the 2nd gen Plugin (2016-2022), 1st gen Plugin (2012-2016) only had a 4.4kWh Lithium Battery. Toyota Prius Plug-in Hybrid - Wikipedia

None of the Plugin models have a ~260hp electric rear motor, more like a 7HP electric rear motor.

No need to go off on tangents, berate or play victim. I am, as I am guessing most are, only interested in learning based on facts and or observations-experiences. Nice to stay on a credible sourced basis.

 

Yes, that is why I was having issues using in non T-Mobile serviced locations. I wasn't able to login to the Autel MAXI AP200 app, which after logging in automatically updates for free for the single free or other(s) purchased. Keep that in mind, if you're logged out of the app, you need to have WiFi or cellular service to login and use the app.
