As expected, the fuse is fine.
Was going back to disconnect the cables to do a hard reset-- realized that, even with the car shut off, the DVD (for the nav system, I assume, I'd never seen in before) was spinning up then shutting off repeatedly as if it were trying to read a disc. Could THAT be the culprit, in therms of battery drain???

 

Did the touch-the-cables-together hard reset. My screen is back - that's good! - but so are the "Christmas Tree" rotating TPMS warnings, which I hadn't seen in a few days. STILL haven't been back to get the battery checked.

 

Try inflating your tires to 40psi and see if the light disappear. I used to have it all of the time, not once since I overinflated the tires.

 

Yeah, I've done that in the past, may do it again. I'm being stubborn. I hate doing something wrong (overinflating) to make another thing right (the warnings going off). I'm sure there's a Life Metaphor in there somewhere.

 

Or go to Costco, give them $20, they will suck all the air out of the tires and put fresh back in. Worked for me.

 

Try having the batteries checked in each wheel sensor. Usually last for about 7 years so if you have the original sensors they may be at the end. Tire shop can check them with a wireless tester.

 

Good idea. Get the nitrogen and have them go over like 2lbs per wheel. I just hate costco.....

I used to use 100% (or so) nitrogen, now I use 76% nitrogen. It's easier.

 

pk4144,
Over inflate to 40lbs, see if the warning disappears, then slowly deflate to normal pressure. It has worked for me in the past.
