I use a KIWI-3 Bluetooth OBD 2 (pricey, but fast easy connection) but any would work as long as it can pair with the OBD fusion software. Once you download OBD Fusion (free) there is an additional 9 dollar add on "Toyota" package. Once the bluetooth connects you can select which PID network you want to connect to (General, Network A, etc....) there is one labeled "Tire Pressure". IF you select that one and make a new dashboard screen that has the tire pressures for each of the wheels on it you can now access the tire pressures of all 4 wheels. Its accurate as I have deflated each wheel to 20 psi one at a time and checked it. The only issue with this is that when you are in the "Tire Pressure" PID network the only accurate readings are tire pressure and you don't see any of the others (RPMs, Speed, Boost, Oil temp, etc...). You have to log out of that and go into Network A for those to be accurate. So other than that hiccup it seems to work fine. I'll post a few pictures later this evening once I have had a chance to take some screen shots.
