OBD II / OBD2 not ready for smog check

Video 1/2 : OBDII not ready: My 2002 Toyota 4Runner failed smog check readiness. The CATALYST is INCOMPLETE. What solved it is to Rev the CAR @ 3000 while on PARK/NEUTRAL in an open space area for 3 minutes. and then drove it for between 35-45 miles per hour for 15 minutes. I also drove it for 50 miles per hour for 15 mins. Then I tested it again , CATALYST OK after that. Meaning, it’s ready for smog check!
Disclaimer: Please practice safety and caution. It worked particularly for me, I don’t guarantee it in any way that it’s gonna work for every one. This video is to share the experience. This is the one that worked for me. Thanks everyone!
Let me know if it also work for you.
