I tried to position the sensors as described and was able to get the front two to acknowledge but timed out at the first rears. New realization came when I started over and the front wouldn’t connect even though they had been woken. The TPMS acknowledged previously so why not immediately when I tried again. They were woken.
I bought a new sync tool this year because I couldn’t find (
remodel house) the one I’ve owned and used twice a year since 2016. The old one synced immediately
each of the nine times I changed the tires.
I looked up the manufacture of the two tools. The one I just bought, and doesn’t work for shit, was made by Shenshengyi and cost $12.65
The previous one, that worked flawlessly, was manufactured by Bosch for GM, and cost $88.63
The problem I had here is the cheap tool.
I bought a new Bosch tool and the sensors acknowledged and synced immediately even with the low battery flashing because I use an old battery

The Bosch tool is on the right. It is larger and the orange surround is soft. Throw the other POS in the trash and buy a new Bosch unit
