Just an update on my case. I took it in to Tesla, fully expecting to pay for a broken Module. Not only was my TPMS light flashing with the tire pressure no longer working, the radio stopped working too.
My car was in the shop 2 days but in the end they said it was Fuse #236 which gives power to the radio and TPMS module. They replaced the fuse and ran firmware. It was great that they didn't charge me anything on my 2016 Model X which is out of warranty.
The last firmware update seemed to cause the issues or at least I didn't have any issues before it. A good outcome as everything is working as usual. Hopefully this helps someone if your TPMS or radio stops working.
Description on my repair:
Performed inspection and verified concern, Removed old tpms module and test wiring. there's reference voltage and power to ground. Wiring shows no issue. Replaced module and performed firmware update. Checked all fuse and found fuse #236 which gives power to radio and also to the tpms module. Replaced fuse and ran firmware. System pass firmware. Performed tpms programing and re-learn. System is working as design at this time.
