Reading Diag code... - Toyota Nation Forum : Toyota Car and Truck Forums

Hey guys,

My check engine light came on this morning while driving in to work. I dont have a reader but I was wondering if there is a way to jump two pins to read the diag code from the check engine light flashing or something?

I was told about this from my friend but I just thought to ask here because he is not a Toyota owner...

Thanks for the response in advance...

Jumper TE1 & E1 on diagnostic connector in engine bay.

Yup, it's like morse code. A specific sequence of long and/or short flashes. Get a helper to jump the terminals under the hood with a paper clip while you watch the flashes on the dash.

The Haynes and Chiltons manuals have a listing of what each code indicates.

The light went away so I will have to do it again a later time. I just wanted to know what it is and now I will not able to do so.

Next time...

unless you unplug the battery every night, the code is still in the computer. jump the diag terminals and see what got stored.
