I used my procal to set the tire pressure to zero. But the computer is saying check TPM system. First time I've seen this. Any thoughts?

Setting it to zero doesn't work. You have to have the option to disable the system on your ProCal
Edited: it should be a free download from Procal.
But why did it just start today? I've had this setup for a few months now.
I set mine to zero and haven't had an issue in 2.5 years.
