TPMS reads right, but still shows warning

Did a small search and couldn't find anything, though I'm sure it's out there. Any others have this issue? I'll post a pic as it will be easiest to see. Basically it's telling me to inflate to the pressure it's already at.

No search required. This is a common sense test.
Inflate the rear tires until they're at 3.3 or so, to get them inflated to a pressure above the lower TPMS limit.
See what happens.

Yup, as Steve mentioned, the way our TPMS system works, you need to get the air pressure at or sometimes above the recommended level for the warning to go away. Once it does, it will allow the normal lower variance you had before. I'm not familiar with your truck's spec, is 3.1 bar the recommended pressure or a minimum?

With psi for example on my truck, it requires 45 psi for the rear tires. I can get them down to about 39 before I get the low pressure warning. However, once you set off the warning, you must pump the pressure back to 45 for the warning to go away. After the warning goes away, you can allow it to drop with no warning lights.

3.1 is 45psi. I wish I could get it to show psi instead, but haven't found a way to do that. I'll try the overfill method and see if it works. Thanks.

You can adjust psi to bar in the settings menu
