2010 Prius: It would be nice if TPMS would display the tire pressure, however, is seems that there is 1-bit (on / off) LED indicator. Obviously if the light is on, then tire pressure should be checked. Questions: 1) What is the tire pressure range for the LED to NOT light up? * 2) Is it possible to readout the tire pressure from ODB or the like? * Any reference would be appreciated.
