OBD II Tool Requirements

Looking at the service manual, there are multiple mentions of an Intelligent Tester...
This is what I have https://autel.com/mk1/3241.jhtml
This is what I think I need https://www.motorpartstore.com/toyota-denso-intelligent-tester-it-2.html

Is what I have good enough or should I get the other tester (at a potentially questionable source) If this one is "too good to be true"... anywhere I can get one if that is what I need?

 

I can tell you the 2nd gen tacoma has limited use for the factory tool, which is called "Techstream"

On any other vehicle from 2005+ theres lots of functionality, but tacoma is very simple and a lot of modules can't even be accessed with the factory scanner.

You autel is more than enough, buy a better scanner if you ever have ABS or SRS issues.

 

I'd at least get something that can read all systems if your budget allows, bi-directional controls would be even better but not needed too often.
