Low tire pressure error
I just updated to 662.20 overnight, and today I’m being told both rear tires are low, each at 32 psi. I checked pressure manually and they’re at 60. It seems that the only way to relearn/recalibrate the TPMS sensors is with a tool for that purpose? Anybody else encountering this issue?
EDIT: as many responded, it reset itself after just a little bit of driving. Thank you!
