When I installed new sensors/wheel, the serial numbers of the TPMS sensors need to be entered into the cars TPMS system.
My TPMS tool scanned the sensors for their serial nuumbers from outside the tire, I plugged the tool to OBD2 connector and uploaded the serial numbers to the car.
I was informed the Toyota TechStream tool was unable to read sensors off the air, and had to be read manually off the sensor, meaning the tire bead would need to be broken, to get to the sensor. I ran fast from the dealer, as they wanted to charge an ARM and a LEG for that. A real tire store can address this issue much more efficiently. :jump:
