That tech article does NOT mention a "diagnosis tool", in any way, shape or form.


If you don't mind me saying so, if you'd have fixed this yourself instead of taking it to a mechanic, you would have learned "relation between cam sensor and cold weather".
yes I read that, but I just don't understand where can I found the codes after I connect those connector, cause I throught I will need a computer thing to plug in the connector, then code will be shown on the screen.

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.

Yes. Again, please read, and re-read, and re-read that tech article until you fully understand it.

No. Please read the tech article. The codes follow one another in a pattern of flashes. The tech article COMPLETELY explains ALL of this!!!

You're welcome. I only wish you would have asked more questions before you assumed that you needed some sort of fancy "diagnosis tool", and sent your car away to someone that may or may not have fixed the problem, and may or may not have charged you for parts that you did not need.

The engine light flashes seem like code 14, from your description.

The OD light flashing seems like code 24, from your description.
