2012 JK Unlimited Wrangler Rubicon.
We just finished up two weeks on Martha's Vineyard. We were on the beach everyday, aired down to 15 PSI. At the end of each day I brought the tires back up to about 30 psi for the short drive back to where we were staying.
The TPMS light was on all two weeks. Since I was about 10lbs under, I didn't think anything of it. Before we left to go home, I brought pressure back up to 37 psi. A week later the TPMS light is still on solid. I've checked the tires and they are at 37 psi cold.
The manual states that a solid light after one min flashing on every engine start signals a "malfunction".
Did something get damaged during the two week air down?
