So it seems that there are some very cost-efficient products you can get to read codes and check engine lights for the 5th gen 4runner, but as far as I know, they only work with Android-based apps. There was a thread on this topic, but I never saw anything for iPhones discussed:

Does anyone have any suggestions for scanner tools and/or apps that are compatible with iPhones?
