I just put on my snows and the car is not picking up the new tires. The user manual says wait 20 minutes, drive over 12mph for up to 10 minutes to "relearn". My 16 mi, 20 minute commute to work did not find the new tires. Is the manual correct? Anyone else have a problem or did TireRack put the wrong TPMS modules in my tires?

you sure it did not say drive on the new tires BEFORE doing a re-learn ?

and are we talking about the car manual or the tire manual ?

NTB has always been good about doing a quick re-learn.

--------------------

NOW if we could type in the ID number of the TPMS sensor into the car computer --then just driving migh work.
but you still need to input the location.

- Swapped out with new tires before driving


From the car manual. It says
"Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a new
tire/wheel position after rotating the
tires or replacing one or more of the
TPMS sensors. When a tire is
installed, the vehicle must be
stationary for about 20 minutes
before the system recalculates. The
following relearn process takes up
to 10 minutes, driving at a minimum
speed of 19 km/h (12 mph)."

I have the Ateq tool from my 2014, that manual had the procedure as missing important first step when doing in the garage, "put on ear protection" :D, set parking brake, hold the menu button....... Not sure the magic sequence to enter the manual learning mode for my new 2019, if it indeed has one.

Well that's odd. On my 2019 Premier I bought new aluminum wheels and tires for winter and 4 new G.M. tpms sensors to go along with the package. Installed them on the car, and everything worked like a charm.

I was told that the batteries in the TPMS units are rechargeable and this charges them up.

Regardless, you'll need a GM TPMS relearn tool:


In my 2018, there is a proceedure for using this tool and the infotainment system to walk through the relearn process. You have to put the system in a relearn mode and then you walk around the car - LF, RF, RR, LR, using the tool to simulate the sensors at each wheel. As you do this, the car gives you audible feedback. (All that is detailed in the owners manual procedure.)

I use a relearn tool (looks like the one above but different brand name on it) on my 2011 Volt and 2017 Bolt and it's pretty easy. The posted 2019 "let sit and then drive" would be a totally new process.

Chevy.com does not have the 2019 owner's manual online yet, but 2018 is up there and here it is:

TPMS Sensor Matching Process
Each TPMS sensor has a unique identification code. The identification code needs to be matched to a new tire/wheel position after rotating the vehicle’s tires or replacing one or more of the TPMS sensors. The TPMS sensor matching process should also be performed after replacing a spare tire with a road tire containing the TPMS sensor. The malfunction light and the DIC message should go off at the next ignition cycle. The sensors are matched to the tire/wheel positions, using a TPMS relearn tool, in the following order: driver side front tire, passenger side front tire, passenger side rear tire, and driver side rear. See your dealer for service or to purchase a relearn tool. A TPMS relearn tool can also be purchased. See Tire Pressure Monitor Sensor Activation Tool at www.gmtoolsandequipment.com or call 1-800-GM TOOLS (1-800-468-6657).

There are two minutes to match the first tire/wheel position, and five minutes overall to match all four tire/wheel positions. If it takes longer, the matching process stops and must be restarted. The TPMS sensor matching
process is:
1. Set the parking brake.
2. Place the vehicle in Service Mode. See Power Button 0 171.
3. Make sure the Tire Pressure info page option is turned on. The info pages on the DIC can be turned on and off through the Settings menu. See Driver Information Center (DIC) 0 133.
4. Use the DIC controls on the right side of the steering wheel to scroll to the Tire Pressure screen under the DIC info page.
5. Press and hold V in the center of the DIC controls. The horn sounds twice to signal the receiver is in relearn mode and the TIRE LEARNING ACTIVE message displays on the DIC screen.
6. Start with the driver side front tire.
7. Place the relearn tool against the tire sidewall, near the valve stem. Then press the button to activate the TPMS sensor. A horn chirp confirms that the sensor identification code has been matched to this tire and wheel position.
8. Proceed to the passenger side front tire, and repeat the procedure in Step 7.
9. Proceed to the passenger side rear tire, and repeat the procedure in Step 7.
10. Proceed to the driver side rear tire, and repeat the procedure in Step 7. The horn sounds two times to indicate the sensor identification 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 display screen goes off.
11. Turn the vehicle off.
12. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading Information label.

Project Tire Change Update. My first attempt failed using my Ateq AT15 tool. I saw there was a firmware and database update for the unit. With new firmware/database my Ateq and Steverino's process detected the tires. Not sure why there is a disconnect between the user manual and my experience. Joeparaski's experience worked like the manual claimed. Maybe the GM OEM TPMS sensors have extra info to avoid the TPMS tool step. We will see in the spring when I put the OEM summer tires back on. At least the horn blast is shorter plus remembering the hearing protectors up front made the process a little less painful.

Thanks all for the helpful hints.

"TPMS units are rechargeable " NO! at least NOT the batteries.
------------------------------
Aggie non tool learning - snow tire replacement:

put all 4 tires in a row using a pipe : spin each tire one by one while using the" Press and hold V in the center of the DIC controls." step
-------
extra credit for using a cordless drill to spin the tires.

Note: make sure your spin the tires the other way in Australia.

Did you guys ever figure you out if you need a relearn tool for a 2019 or not? I'm also looking for confirmation on the 2019 stock TPMS sensor part number. I'm thinking that it might be part of what could make it auto learn. Thanks,

Easy enough to test. Lower the air pressure on one wheel, rotate the tires. Drive it for half a block or so. Does the lower pressure tire location correctly show it's new position?

The “relearn process takes up to 10 minutes, driving at a minimum speed of 19 km/h (12 mph).”
Our blocks here are a mile long, so about two blocks, :)

Thanks for the added detail, bentbiker!
