With a paper clip in the connector, how could you plug anything else into it?

If you read the tech article, and maybe didn't understand part of it, why didn't you ask?

Your "check engine light" is really called a "malfunction indicator lamp" by Toyota. This from the very first paragraphs of the tech article:
"The ECM contains a built-in self-diagnosis system by which troubles with the engine signal network are detected and a malfunction indicator lamp on the instrument panel lights up...
The diagnostic trouble code can be read by the number of blinks of the malfunction indicator lamp when TE1 and E1 terminals on the data link connector 1 or 2 are connected."
Again, this tech article does NOT mention a "diagnosis tool", in any way, shape or form.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
