Well I had this very issue after purchasing a new OB2 reader and trying it out on my 2003 4Runner Limited V8 over the weekend. Funny enough I have another code reader that does not trigger this fault code on my 2003... very odd as I used that old reader 10 or so times to clear codes and never had this VSC TRAC and VSC OFF light issue.

Needless to say, I followed the Paper Clip method of sticking the clip into socket TS and then just touching it to CG, no need to physically stick the clip into the socket all the way to get this TSB to work.

Thanks for the great write up! I was able to do this on my own in 5 minutes before a meeting!
