Before anyone says read the owners manual, I have already looked there. This morning I had to replace the battery in my Z06. Reindexed windows. Reset clock. No problem. Now my TPMS shows 0 for all tires. Do I need to reprogram or will they reboot once I drive it ? TIA.

My TPMS showed "XX" for all tires. I bought a programer . It would not re-progam. I had new sensors installed. Then the programming tool would work.
I never had all "0" though.
The battery disconnect would have erased and reset the last stored pressure values. That would explain the '0' reading. What's not clear to me is under what circumstances the sensors get polled, and whether or not they actually sleep. Once, after my car had sat overnight, immediately when I started the car, I got a low pressure warning from the RR wheel because there was a screw in it. The car wasn't moved, so nothing I did would have woken the sensors up. And yet the sensors must have been polled at start up to get a reading, and must have been awake to provide one. In the OPs case, doesn't sound like the sensors got polled. Also, if a sensor can't be read, the resulting display is XX, not 0.
They keep changing how they work over the years. In the early years, the tire had to spin in order to transmit the information to the PCM. I do not think it would even show pressures until after the car moved.
Now, in my F250, it just shows the air pressure changes without moving the vehicle. My Prius does the same thing. It shows low pressure. Then I add air and the low tire notification goes away without moving the car.
I guess I could go see what the owner's manuals say.
