Default What is that button?

Anyone look under the steering wheel of their Lexus GS 350? Right next to the OBD connector, there is this little black button, what is it?

Do you have PCS? Could it be the TPMS reset? Does it have a little picture by it/can you take a pic of the button?

So, is that how you reprogram the TPMS sensors or something? I know on the passenger side, there's a switch under there, which is switch position 1 and switch position 2, for up to TWO TPMS settings on the car.

Yes I believe this is how you reset it. The switch on passenger side is to swap between (like you said) winter and summer tire sets.

That's the button to reinitialize the tpms system. Basically holding the button for more than 3 seconds will cause the tpms system to reset and recheck all tire pressure and sensors
