So I put new wheels, tires, and TPMS sensors. I’ve tried the relearn a couple of times. This morning I did a 50 mile run just trying to do the relearn. No success. Is there a way to do them manually? I have the tool from my c6 days.

The C7 tire pressure sensors transmit their data to the TPMS module on a frequency of 433MHz.
1. start car - actual engine running - not the Acc mode
2. Select the tire pressure display in the DIC.
3. Press and hold the SEL button until the display changes and the horn beeps. It now says it's in learn mode.
4. Now drive just as it says in the manual - 10 min or so above 12 mph.
5. Suddenly, it will find all 4 sensors and show pressure
6. when you shut the car off , the "learn DIC" will show again and horn beeps.
1.5 yrs ago I bought tires, wheels, and sensors all mounted and balanced from Tire Rack. I installed them on the car and went for a test drive. I got back home 30 min later and realized I had never seen any warning lights re; tpms. Since then I swap tires back and forth twice per month to run autocrosses and tpms system works perfectly w/ both sets. I suspect you have the wrong sensors.
Which brings me to ask what TPMS sensor units are you using on your car?

I dont know the name (they were sent with my new wheels) but the tire installer stated they were not OEM. Work fine (so far) and take all the same measurements as OEM.
I have that same tool, WW. When i got home, I set the car to learn mode, went to each tire and activated the tool. After the 4th wheel the car honked once. I think synced them. I haven't driven it yet to verify. Thanks for the replies. I will update when I drive it again.
I don't know the brand name of mine either. Ad says replaces GM part# 13581560 GM part# 13598775

When going to the track I just swap wheels and drive, the car learns the new sensors without doing anything else.
update: I made a few afternoon runs today. I still couldn't get them to sync. So I'll try to see if Discount tire can do it. I'm thinking these may not be for 2019 as stated in the ad.

I talked to our local dealer yesterday. He said they could only program OEM sensors, and recommended a local tire shop. I went there today and they couldn't get then to sync with the car. So I made the 30 mile drive to my nearest Discount Tire shop. They were able to program them. However, on the way home the front left quit working. I made a stop to see my son, when I got back in, the front left was working. But now the front right stopped working. I'll work with them a little longer before I give up and change all the sensors. Does anyone know of a OEM gloss black sensor for the c7?
