Found out today that my TPMS sensors weren't activated.. It was linked with the BCM, but its not reading anything at all (Reads 0 psi).
This is what happened today.
One of my tires was running a little bit flat, so I went ahead to check the tire, and it was under pressure (24-25psi). Then, it surprised me that even at 24-25psi, the TPMS did not trigger any kind of warning, so I got a friend to check on it. Turns out that all of my TPMS sensors was inactive.
I know that no one would purposely check if the TPMS was working or not when they first got the car, but since it happened to me, it could have happened to you too!
Just a heads up
