     I have the same problem with my 2013 RAV4 XLE. I have tried both the TS501 and TS508WF. The code shows up immediately even when I send a clear codes. I want to send back my TS508TF.

    Hi, press reset button and just drive your car for a while so the car can recognize and
    learn the sensors, only when you mounted new sensors you need to have a special
    Toyota equipment.
