hi. go to maxidas.com and download Toyota coverage functions. ...it should tell you there what the ds708 will/wont do. I have used the relearn/reset function, on other cars, so I can say that it does do it....I just dont know about Toyota.
hope this helps.

 Hi yes  i have been able to do it on this year and model  although i personally like to drive the vehicle for a couple of miles  it  does the same thing it will relearn the new values by it self   another thing you can do is jump pin 4 and 13 of the dlc diagnostic connector for 30 minutes  this will reset and relearn  everything  including the  ignition key if ecm was to be replace  hope this helps post back any results  good luck
