Programming TPMS

What is your question?

Low tire light was on, on the dash. Also said service TPMS. Couldn’t get anything to program. Put vehicle into learn mode and still couldn’t reprogram TPMS. Vehicle wouldn’t honk at each wheel. I bought a different BCM and had it clowned. Also bought a different BCM antenna and installed it. Put in another set of TPMS. Now when I put vehicle into learn mode it will honk after each wheel like it’s supposed to. Low light is still on. I have drove it for multiple miles low light still on. When I use my scanner for live data. It shows the tire pressure on each wheel bouncing around from 12lbs all the way up to 212lbs while driving. I’ve tried 2 different sets of TPMS and still the same thing. Does anyone have any ideas on what I need to do? Thank you for your time.
