Tire System Fault - newer system

I have looked at the various threads, but can’t come to some conclusion as to what’s wrong with my TPMS. Most threads relate to the older system.

Stats: 2012 DBS Volante - that I just took out of long-term storage. I usually put in 60psi for storage and once removed, I let pressure back down to spec. 36F & 38R. In the past, the warning would show up and after driving around for awhile it would reset. But not this time, and several attempt, the warning continues to come back on. The car always has a battery tender on it in storage, no other dash lights or warnings, nothing else is acting up. The tire pressure that comes up on the display is the correct pressure in all the tires, so the sensors must be sending a signal and the module reading them correctly.

Things I have tried:
1. Adjusted air pressure twice.
2. Let the car run through the system check before starting.

Does anyone have any suggestions or ideas?

8 year life regardless of mileage. You need new sensors. Aftermarket ones available for a reasonable price. Self learning system, just fit and drive.

The warning on new TPMS appears when the system detects low battery in TPMS sensors regardless of the PSI in your wheels, so it seems you need to replace your TPMS sensors before they are dead.

Input was very helpful. New sensors have been ordered and on the way. Thank you for your quick responses.

Sensors are getting to their end-of-life stage. Battery dying in one of the tire sensors?
