Adjust time pressures. This should remedy the issue.

Be sure to adjust your tire pressures in the AM, before your drive the vehicle.

IF, your "--" continues, adjust all tire pressures a bit over 37# and give some miles driving and then adjust back down to 37 psi or your preferred psi.

If doing the above does not remedy the "--" you may have a problem with that wheels sensor.

What if you have beadlocks with 25 PSI max? The factory sensors worked fine on my new raceline beadlocks and Nitto 38x13.5R17's at 25 PSI. Worked fine when I dropped all four to 9 PSI. Inflated all four to 22 PSI and they worked, Then one by one I got the red __ on each wheel, then Service tire pressure system

Inflated all four to 27 PSI and they came back online.

BTW, I taser set the minimum pressure to 25 PSI, it won't go lower. I've seen several video's where they go lower. 2021 JLR built in May 2021.

Hopefully the JMR lets you set the low warning for low range driving to 1 PSI if you want.
Here's a pic of __ from another thread where op never learned to google search.
