I replaced all 4 tpms sensors recently and now the tpms system wont work.
Sometimes driving the check system for the toms goes away and it works fine but that only lasts like 2 minutes. Only codes up are C2111.

 

What year of the car, what kind of tpms, OEM? lower models are not self-learning so you may need to reprogram them. I just replaced all 4 TPMS of my 08IS350 2 months ago with OEM and they are not the same anymore. Every time I park inside the garage, the low tire alert comes up. But I have a second set inside the garage that are also programmed as 2nd set for this car so it might be sensing them - as soon as I drive away from the garage, the alert also goes away.

 

07IS250. i dont have a second set. they are oem yes. but im not getting a low tire warning. im getting a check system warning.

 

That's exactly what I've been thru after replacing the original set. I got a check system for weeks and had to reprogram them a couple of times. Then one day it just went away. Now, the low tire alert in garage but I'm sure it was just the 2nd set.

There is a step to reset the TPMS system - by holding that circle button for a few seconds while you're in that menu. I can't tell you specifically since I brought my RC today at work. But it's when you are in that TPMS menu.
