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.

How to reset Chevrolet Traverse LTZ 2012 TMPS with EL-50448

Today, I’ll chip in words of experience of EL-50448 TPMS reset on my Traverse LTZ 2012.

TPMS Reset Tool:

EL-50448 from http://www.obdii365.com/wholesale/el-50448-tpms-activation-tool-oec-t5.html

Car: 2012 Chevrolet Traverse LTZ

TPMS: (this part for newbies only; skip this part if you’re experienced)

– what is TMPS & why do you reset TPMS?

The tire pressure monitor system (TPMS) of the Chevrolet Traverse, model years 2007 – 2013, alerts the driver when a large change in the pressure of one tire exists while the vehicle is being driven.

The system will also display individual tire pressures and their locations on the driver information center (DIC). The TPMS uses the engine control module (ECM), body control module (BCM), instrument panel cluster (IPC), DIC, remote control door lock receiver (RCDLR), a radio frequency (RF) transmitting pressure sensor in each wheel/tire assembly, and the serial data circuit to perform the system functions.

When the vehicle is stationary, the sensors go into stationary mode. In this mode, the sensors transmit once every 60 minutes to minimize sensor battery consumption. As vehicle speed increases, the sensors go into drive mode, in which they transmit once every 60 seconds.

NOTE: The sensor’s pressure accuracy is about 2 psi (14 kPa) at temperatures from 14 degrees Fahrenheit to 158 degrees F (-10 degrees Celsius to 70 degrees C). The RCDLR receives and translates the data contained in each sensor transmission, then sends the tire pressure and tire location data to the DIC. When the TPMS detects a significant loss or gain of tire pressure, a “CHECK TIRE PRESSURE” message will appear on the DIC, and the low tire pressure warning indicator is displayed on the IPC.

The RCDLR has the ability to detect malfunctions within the TPMS. Any malfunctions detected will cause the DIC to display a “SERVICE TIRE MONITOR” warning message.

– when do you reset TPMS?

When the TPMS detects a significant loss of tire pressure, the “CHECK TIRE PRESSURE” message is displayed on the DIC and the low tire pressure indicator is displayed on the instrument panel. Both the message and indicator can be cleared by adjusting the tires to their recommended pressures and driving the vehicle above 25 mph (40 km/h) for at least two minutes. If the warning indicators are still on or the display shows dashes instead of a value, there is a problem in the TPMS. The RCDLR has the ability to detect malfunctions within the TPMS.

Any malfunctions detected will cause the DIC to display a “SERVICE TIRE MONITOR” warning message. See appropriate manufacturer service information.

Review: how to reset TPMS with EL-50448

Remember when you could relearn the tire sensors with nothing more that the DIC and a user’s manual? Well, apparently GM decided that was too much freedom for the owner of one of their vehicles so what was their solution? Make it so the dealer would have to be consulted- and quite possibly for a fee. Well, my troubles are over! I used this on a 2012 Chevrolet Traverse LTZ and following the user’s manual, the horn beeped at the appropriate times and the tires were sensing in the proper position (as tested by releasing air to see a visible change in the DIC). This may seem trivial- until you have a small non-visible leak on a tire and right front is actually left rear!

This was my procedure for those who want to know, and as outlined by the user’s manual starting on page 10-46.
1. Set the parking brake.
2. Turn the ignition to the ON/RUN position with the engine off (the second click before the cranking spot but one click after the acc).
3. Press the Remote Keyless Entry (your key Fob) Transmitter’s LOCK and UNLOCK simultaneously for about five seconds. The horn will beep twice to signal the receiver is in relearn mode and TIRE LEARNING ACTIVE will be displayed on the DIC.
4. Start with the driver side front tire.
5. Place the relearn tool against the tire sidewall, near the valve stem. Then press the button of your very handy dandy VXScan EL-50448 (after you install a 9-volt battery of course) to activate the TPMS sensor. A horn beep confirms the sensor ID code has been matched to the tire and wheel position.
6. Proceed to the passenger side front tire and repeat the procedure in step 5.
7. Proceed to the passenger side rear tire and repeat the procedure in step 5.
8. Proceed to the driver side rear tire and repeat the procedure in step 5. The horn will beep two times to indicate the sensor ID code has been matched to the driver side rear tire and the TPMS sensor matching process is no longer active. The TIRE LEARNING ACTIVE message on the DIC goes off.
9. Turn the ignition to LOCK/OFF.
10. Set all four tires to the recommended air pressure levels as indicated on the Tire and Loading Information label.
11. Enjoy your liberation from the GM dealership!
