El-50448 Reprogram 2019 Chevy Impala TPMS sensors

 Hi, I’m going to be doing a demo and a quick review of this Augocom El-50448 TPMS relearn tool, so this will work for GM vehicles that are approximately 2011 and newer and I’ll be doing this procedure on my 2019 Chevy impala.

 

So the way these cars work every time you change tires or change TPMS sensors, you have to do a re-learn and you do require an external tool. On some of the older cars, I think there was some sort of memory, but on the newer cars, you’ve got to use a tool.

 

I bought this El-50448 from China and there’s a number of identical looking units, I’d actually originally bought a different identical one but it didn’t work, so I returned it and bought this one, this has got some branding on it “Augocom”, this one works really well I did it when I put on my snow tires.

 

So anyways I’ve just taken off my snow tires and put my all sensors back on, so we’ll do a bit of a demo.

So, another thing which is kind of cool about this El-50448 that the other one I got didn’t have is a little manual it’s not really required, but you know.

 

So the tool itself is pretty small, it’s got a nice little cover on it and it’s powered with I believe it is a single 9 volt battery which is not included.

 

And it comes with just a single button. And even though it looks like you should just be touching it, and then letting go. What I found is you actually have to be holding the button until each tire learns.

So, before I start I’m just gonna turn on the car just so that you can see that nothing’s programmed right now, so there’s a service tire pressure monitor system warning and you can see that there are no pressures shown. So I’m just going to turn that off.

 

And let’s enter learning mode, so in my 2019 Chevy Impala and I’m assuming many similar GMs to do that. All you have to do is hold the start / stop button for five seconds.

but do not press down the brake during this time.

                                

So now it goes into this diagnostic mode and just a couple other things to point out when I had the other sensor that didn’t work I was trying to troubleshoot. Some people were saying that you want the wheels to be facing relatively straight for it to work, so that’s just a tip I guess and the other thing is I put my key fob in the car so that when I go out to do the re-learn, the car isn’t confused that the key fob is gone I don’t really know if that’s required but I figure I might as well.

So now we’re in here and all I’m going to do is hold the check Mark until it goes into re-learn mode.  So now we’re doing tire learning and we’ve got to start with the front left (tire), so you just put this right beside the valve stem and hold until the car beep.

Then we’re gonna go to the front right tire and same deal.

so you can see, it’s not consistent timing, sometimes you have to hold it for a little while before it registers.

 

Then the rear right, and then the last is the rear left. Okay, and so those last two beeps.

 

We’re just saying that it was successful and if I get in the car I can see that I’m getting readings.

Now to finish everything, we can just hit the stop / start button.

 

And then we should be good to go. So I’m just gonna start the car.

And we can see the tire pressures are all shown there and I’m just gonna shut it off because I’m inside the garage and that’s all you have to do.

 

Now one last thing I just want to mention no matter what brand you get, make sure you put this Augocom El-50448 somewhere that you can find it. It’s fairly small and it took me an embarrassing amount of time to find before making this demo and review.

 

So I mean El-50448 is obviously a pretty simple device, it sells for $12 dollars here:

If you have one of these GMs with the TPMS, and you change your tires, it’s definitely worth the investment.

Autel MaxiTPMS vs. Bartec Tech TPMS tool

Being a tire and service technician for several years, I sometimes encounter several vehicles (Toyotas included) with problems related to the sensors in their tire pressure monitoring systems. I saw them with broken valve stems, dead batteries, no sensors inside the tire (unless they're indirect or they're not equipped with TPMS in the first place since Canada doesn't make it mandatory like the United States and several countries worldwide since 2008) and, once in a blue moon, one sensor that self-destructed to pieces inside the tire. Fixing them is easy, once you know what you're doing with the right replacement TPMS sensor and diagnostic tool to pinpoint the faulty sensor and perform a proper relearn. The shop I work with uses a dual-band Schrader EZ-Sensor (#33500) and a Bartec Tech 400SD TPMS tool with OBD-II capability. They're great to have, but the software support for the tool ends on December 21, 2020.

Looking at the options to replace the tool, I saw one that attracts the interests to tire shops and suppliers: the Autel MaxiTPMS TS508. Being a combination TPMS tool with OBD-II capability, it has all the right features for the shop to activate and diagnose TPMS sensors, plus free lifetime software updates. Of course, that comes with a catch. With any TPMS tool with free lifetime software updates, you're stuck with programming one kind of universal TPMS sensor. In the case with the TS508 (or any Autel TPMS tool), the tool can only program Autel's MX-Sensors. Whereas with the Bartec (along with Ateq's VT-56 and its derivatives), you can program a variety of aftermarket replacement TPMS sensor, but you have to pay a hefty subscription fee to keep your tool up to date. Drawbacks aside, I gave the latest MX-Sensor a try. I was impressed with the highest vehicle coverage, the ability to change valve stems from rubber snap-in to metal clamp-in at the push of a button, and the capability of programming up to 16 MX-Sensors at once.

Which Tool to Pair 2019 Toyota rav4 TPMS Sensors?

Car model and year: 2019 Toyota rav4

Purpose: looking for an aftermarket or OEM device that would allow me to pair my TPMS on my winter tires.

Advice:

Toyota uses a proprietary system, Honda, and Chrysler for example don’t and I understand if you install an unprogrammed module itself programs with those makes, I just updated the TPMS from some winter tires on a 17′ Rav4 to a 19′ Rav4 and the TPMS sensor had to come out and be placed in the TPMS programmer to accept the new car data, I looked for one to buy, read here somewhere someone bought one from Tire Rack, called them, they disagreed, they had nothing, so.

Find a friendly tire jobber and try your luck, I understand Toyota can do it, but then you have to reprogram every winter summer wheel switch.

Background:

After the TREAD Act was mandated in 2007, all vehicles manufactured in the United States beginning in 2008, must be installed with direct or indirect TPMS systems.

The Toyota RAV-4 is installed with a direct TPMS system, which means there are TPMS sensors in the wheel. If one or more tires indicate low tire pressure, the TPMS sensors will transfer the information to the vehicle’s ECU. An indicator light (low-line TPMS system) or each tire pressure will show on the dash (high-line TPMS system).

A TPMS relearn is recommended after a sensor replacement or tire rotation. When services are performed, such as a tire change or TPMS sensor replacement, in one or more tires of a Toyota RAV-4, a TPMS relearn must be performed to transfer the sensor information to the vehicle’s ECU.

Type of TPMS system:

Direct TPMS, sensors are installed in the wheel

Sensor Frequency:

315MHz

Type of TPMS tool required for TPMS reset:

Option 1: Techstream and mini VCI interface cable ($20-$30) on a laptop will work fine.

Techstream can program the car and is essentially free but not the easiest to use. It also has a ton of other uses (e.g. program key fobs).

Option 2: Autel MX-sensor TPMS sensors can be cloned to match the IDs of your existing sensors – no need to then program the car when swapping wheels. Sensors are ~$25 each, the programmer/reader is another $50. I am running this setup on a Lexus, Rav4.4 and a Nissan.

Option 3:  Carista Android/iOS app can program the car. I got mine for $40/lifetime but they since changed to subscription model ($9 per day IIRC). The good thing is that it is possible so likely someone else will come up with a cheaper alternative soon.
