TPMS

Has Anyone had a lo battery alarm come up on their TPSM? Went to start our Renegade 36vsb today and saw this yellow light above our tire pressure monitor alarm. It showed no tire pressure and a battery symbol with the no pressure alarm. Checked all 6 tires and none are down more than a few pounds. The coach has been setting for a while though. I do have 14.1psi according to my dash indicator and the engine did start right up. Any help appreciated.

Tire pressure monitoring units are notorious for failure, but a pressure differential of 4 PSI between tires will also set most of them to alarm. It could be as simple as the units in the wheels are at the end of their battery life, too. Bring all the tires up to recommended pressure levels and see if the alarms reset themselves. They will not if the internal batteries have gone dead, then it is time for replacement.
